How to use screen mirroring on Windows 10 to turn your PC into a wireless display

If you need to expand your screen real estate, and you don't have a second monitor, you can use another Windows 10 computer, and here's how.

Windows 10 screen mirroring feature

Windows 10 includes a screen mirroring feature known as "Project to this PC," which uses the Miracast standard to seamlessly project the contents of the screen to another computer (or supported devices, such as smart TV and streaming sticks like those from Roku) wirelessly within the same local network.

This is a useful feature that can come in handy in many scenarios. For instance, if you have to work from home, and you need a dual-monitor setup to improve your productivity, and you don't have a second monitor. Or you want to connect a laptop to your smart TV (from Sony, Samsung, etc.) to watch videos or play games, but you don't have the required physical connection – just to name a few. It's an invaluable feature that's simple to use.

Whatever the reason it might be, you can use the "Project to this PC" settings along with the "Connect" app to turn a Windows 10 computer into a wireless display without the need for extra hardware or software.

In this Windows 10 guide, we'll walk you through the steps to use another device as a wireless display with the screen mirroring feature built into the system.

How to use PC as a secondary wireless display

If you're looking to screen mirroring on Windows 10, you'll need a source and destination device supporting Miracast technology connected to the same network, and you will need to follow some specific steps.

Destination device (projecting to)

To enable "Project to this PC" feature on the device you want to convert into a wireless display, use these steps:

  • Open Settings .
  • Click on System .
  • Click on Project to this PC . Quick tip: If you see a red message saying: This device doesn't support Miracast, so you can't project to it wirelessly , then it means that you can't use this feature.
  • Use the "Some Windows and Android devices can project to this PC when you say it's OK" drop-down menu and select the Always Off option.
  • Use the "Ask to project to this PC" drop-down menu and select the Every time a connection is required option.
  • Use the "Require PIN for pairing" drop-down menu and select the Never option.
  • Open Start .
  • Search for Connect and click the top result to open the app.
  • Click the arrow button in the titble bar, next to the left of the minimize button, to enter in full-screen mode.

Once you complete the steps, the Connect app will open to accept mirroring connections from another computer.

Source device (projecting from)

To project your screen to another computer on Windows 10, use these steps:

  • Open Action Center . Quick tip: You can use the Windows key + A keyboard shortcut, or you can click the Action Center icon in the far right of the taskbar.
  • Click the Connect button.
  • Click the device you want to project the screen. (It may take a while to appear.)
  • (Optional) Check the Allow mouse, keyboard, touch, and pen input from this device option.

After you complete the steps, the screen from the source device should display in the destination device like a secondary monitor.

Customizing the wireless display

Once the connection is configured, the "wireless display" will be available as a regular monitor in the Display settings, which means that you can change its resolution, scale, orientation, as well as set it as extended or duplicate mode.

To customize the wireless display, use these steps:

  • Click on Display .
  • Under the "Rearrange your display" section, select the wireless display. (Usually, this is the last display on the list.)
  • Under the "Scale and layout" section, select the desired scale. (It's recommended to use the same scale value as the other displays.)
  • Specify the desire screen resolution.
  • Specify the desire display orientation (landscape or portrait).
  • Under the "Multiple displays" section, use the drop-down menu and select the Extend (recommended) or Duplicate option depending on your scenario.

After you complete the steps, you can start working on the display wirelessly as it was physically attached to the computer.

In the device you're projecting from, you'll also notice a toolbar. If you click the Settings (gear) button, you'll have three choices (Gaming, Working, and Watching videos) to optimize the stream.

Disconnecting wireless display

If you no longer need to use screen mirroring, you can click the Disconnect button from the toolbar that appears at the top of the primary monitor, or you can use Action Center or Settings app.

To disconnect a wireless display using Action Center, use these steps:

  • Open Action Center .
  • Under the device, click the Disconnect button.

If you want to disconnect from the Settings app, open the experience, and then, on System > Display , at the bottom of the page, click the Connect to a wireless display option. Under the device, click the Disconnect button.

Method #1. Connect Laptop to TV Using HDMI Cable

If the Laptop has a HDMI Port, it can be easily connected to TV using a basic HDMI cable. If the Laptop only has USB Ports and lacks a HDMI port, you can still connect the Laptop to TV using a USB-to-HDMI Adapter .

2. Select your Smart TV as it appears in the slide-up menu on your computer.

If the TV does not appear in the list, click on the Detect option and allow the computer to detect and bring up the Smart TV for selection.

If the Laptop still fails to detect the TV, it is likely that your computer is not equipped with Miracast technology.

In this case, you will have to use a Miracast Adapter or use devices like Google Chromecast, Amazon Fire TV Stick or ScreenBeam USB Transmitter from Actiontec.

Method #3. Project Laptop to TV Using Chromecast

An easy way to Project Laptop screen to TV is by using Google’s inexpensive Chromecast Device .

1. Plug HDMI End of Google Chromecast Device into HDMI Port of the TV and plug USB End of Chromecast to USB Power Adapter .

Note: On most Remote Controls you can change the Input Source by pressing Input or Source button.

Press the designated button on the Remote Control and make sure the Television display changes to the selected HDMI Port.

3. Setup Chromecast using steps as provided in this guide: How to Use Chromecast on Laptop Computer .

4. Once Chromecast Device is setup, open Google Chrome browser > click on 3-dots menu icon and select the Cast option in the drop-down menu.

How to Use a Laptop as Monitor For Another Computer

Give a purpose to your spare laptop and use its screen as a second display.

Laptop as Monitor For Another Computer

Multi-display computer setups are quite popular these days. You get ample screen space compared to the smaller display on a laptop. But did you know that you can use a laptop as a second screen for another laptop or desktop? Microsoft offers Miracast support in Windows 10 and 11, enabling you to project your desktop over the Internet. 

You can repurpose a spare laptop and use it as a second display. Consider it a cheaper way to build a multi-display setup if you don’t want to purchase an additional monitor. You will need a Windows 10 or 11 laptop with a working Wi-Fi adapter for wireless connection. Both the computers must have a working internet connection. However, they can be connected to different networks. 

We will discuss the preparation process of configuring your laptop to act as a monitor and some settings to make the experience as smooth as possible. If you want to connect your laptop to an external monitor, see our guide on how to close your laptop and use an external monitor . 

How to Configure Your Laptop to Be a Monitor for Another PC

You must configure the projection settings on your Windows laptop to use it as a second display for your main system. 

1. Open Projection settings . You can do this by launching the Start Menu, searching “Projection settings,” and clicking on the first search result.

2. Change the following settings .

  • Some Windows and Android Devices can project to this PC when you allow them to: Select the Always available on secure networks option.
  • Ask to project to this PC: Select the First Time Only option. You won’t get a popup every time you want to project to the laptop.
  • Require PIN for pairing: Select the First time option. Since it is your laptop, there is no need to enter the password every time.

3. Click the Launch the Wireless Display app to project to this PC option.

The Wireless Display app will open.

How to Project Your Main System to the Laptop’s Display

1. Open Display Settings on the main computer (the one that will be doing the projecting). The easiest way to do this is by searching “Display” using Windows Search and clicking on the first search result.

2. Click the arrow icon to expand the Multiple displays section.

3. Click the Connect button next to the Connect to a wireless display option . 

4. Select the laptop display from the list of available displays. 

5. Note down the PIN visible on the laptop’s display.

5. Type the PIN and click the Connect button .

6. Select the Allow mouse, keyboard, touch, and pen input from this device check box . If you ignore this option, you cannot use the input device connected to your main PC. Only the laptop’s trackpad and keyboard will work.

7. Click the Extend option .

8. Select the primary audio output device from the list. If you don’t do this, Windows will use the laptop’s speakers to play audio. After this, your main display will extend to the laptop screen.

9. Hit the Windows key + K and click the Disconnect button . It will disconnect the laptop display and free it up for other tasks.

Projecting your main display to a spare laptop helps you get more screen real estate while not spending a dime on an additional monitor. However, your second laptop will need a stand to adjust its height to match the main display. You won’t be able to use the spare laptop for other tasks unless you close the projection connection.

Screen mirroring in Windows 10: How to turn your PC into a wireless display

Here's how to turn your Windows 10 machine into a wireless display

Turn your Windows PC into a wireless display

Windows 10  has the ability to mirror your screen to any dongle or device (streaming box, TV) compatible with the popular Miracast standard since its launch in 2015. Microsoft's OS now lets your PC become the wireless display, receiving Miracast signals from a smartphone , tablet , or other Windows laptops or desktops.  If you have a small Windows 10-powered laptop hooked up to your TV, it can now double as a wireless display dongle for your phone or laptop. When you're mirroring from a Windows 10 laptop, you can extend rather than duplicate the screen so you can, for example, stream a movie on the receiving display while you send emails on the primary one. Just imagine taking a tablet, propping it up next to your laptop, and using it as a second monitor on the road. Sharing is caring: here's how to share your screen in Windows 10 (with or without the internet). When you're done, check out if it's worth upgrading to Windows 11 . 

How to turn your PC into a wireless display 

While most modern devices with Wi-Fi have the ability to send out a Miracast signal, compatibility is spotty at best. Sometimes you have to try casting your screen three or four times before the process works. So be patient. If you accidentally rotated your screen while attempting to extend your display, we have a quick fix for that.

Looking to do screen mirroring on Windows 10 ? Here's how to turn your Windows 10 PC into a Miracast-capable wireless display:

1. Open the action center.  (It's represented by the speech bubble icon in the lower right corner of the screen.)

2. Click Connect.

3. Click Projecting to this PC. (A settings window will appear.)

4. Select "Available Everywhere" or "Available everywhere on secure networks" from the top pulldown menu. 

5. Select "First time only" or "Every time a connection is requested" under "Ask to project to this PC." (I recommend picking "First time only," unless you're really worried that some rogue thief is going to grab your phone and project to your computer without your permission.) 

I also recommend leaving "Require PIN for pairing" off since you have to grant permission on the receiving computer anyway. You can also decide whether you want your PC to receive projection requests only when it's plugged in.

6. Click Yes  when Windows 10 alerts you that another device wants to project to your computer.

The Windows Connect app will launch in its own window. You can drag, resize, or maximize the window. We found that videos played smoothly in a connection between a Surface Pro 4 and a ThinkPad T440s .  Also, if the sending device is a Windows 10 PC and allows it, you can use the keyboard and mouse on the receiving computer to remotely control the sender.

How to mirror your Windows 10 screen to another Windows 10 device

Here's how to broadcast your screen from the sending device, if it's a Windows 10 computer. ( Android devices have different wireless display menus.)

1. Open the action center.

2. Click Connect.  A list of available receiving devices appears, and your other computer should be on it.

3. Select the receiving device. You may have to wait a minute or longer for the devices to pair. If the connection fails, you'll need to try again.

4. Toggle Allow input to on if you want to let the receiving device control your PC with its keyboard and mouse.

5.  Click Change projection mode and select Extend  from the menu that appears if you want to use the wireless display as a second desktop, rather than a mirror of your current desktop.

6. Click Disconnect when you want to terminate your connection.

How to Share your Laptop Screen to Another Laptop

windows

Windows 10 was released three years ago and It has so many features that users are still discovering today. It has so many hidden features that finding them just makes everyday use of Windows 10 much more wholesome. In-built hotspot, one-touch screengrab, and the one that I recently discovered Projecting your screen to another Windows 10 computer using the Miracast Standard.

This is a very useful feature if you’re someone like me that shuffles work on different computers and then get confused where did I save my presentations. I can just project the other computer on my screen and control that computer to complete my work and then save it on the cloud.  You can use this feature if you don’t have a secondary monitor but you have a spare laptop running Windows 10.   

You can also use  Teamviewer to mirror your screen, but with  this method, you can share your laptop screen to another laptop and use it as an extended display. Also, since it’s a  Windows native feature, it has much higher speeds than Team Viewer.

It can mirror your computer Display to a computer or TVs Windows support Miracast (or using an Intel compute stick) and use it as a second screen with a Windows 10 computer or tablet. And t his works not just as a mirror but also lets you control the projected computer.

How to Share your Laptop Screen to Another Laptop

Before we begin, make sure you have two Windows 10 computer that supports Miracast. To check if your computers are eligible, go to Start , and type in “ Project to this PC “, if you see an option in the Settings menu, it means it’ll work for your system.  The earlier version, Windows 8.1 supports only mirroring. There are apps available to use this feature if you don’t have windows 10. You can install Airserver Universal for Windows and use it to cast or mirror your computer screen, its a paid software though. We have this little tutorial for you on how to share your laptop screen to another laptop, both running Windows 10.

Read: Cast Screen to TV without Chromecast

Make sure you have at least two Windows 10 computers and are connected to the same WiFi network.

Now, take hold of a computer on which you wish to project the computer screen. Let’s call it Computer Blue. The Computer Whose screen will be projected, we’ll call it Computer Orange.

First Computer

Press the Start button on Blue and type “ projecting to this PC ”, you’ll see the icon under settings. Click the icon and a window will appear.

Select ‘ Available Everywhere ’.

Now we’ll move on to permissions.

In the next drop down bar, you can set when a computer should ask for permission to project. We chose ‘ every time ’ but you can choose ‘first time only’ too if you’re going to use this feature often.

Next is the Security pin, you can turn it OFF if you only use it in your home or office but it is recommended so it is best if you leave it ON.

  • Plug an HDMI cable into your laptop and the projector (using an adapter if necessary), then turn on the projector.
  • Open the display settings on your laptop and adjust as necessary.
  • Use mirror display to project your desktop, or extend display for the projector to act as a second monitor.

This article explains how to connect a laptop to a projector to project the desktop or use it as a second monitor.

Do You Need an Adapter to Connect a Laptop to a Projector?

Depending on the ports available on your laptop, you may or may not need an adapter. Most projectors include an HDMI input port, so you probably won’t need an adapter if your laptop has a full-sized HDMI port. The same is true if your projector has a VGA input and your computer includes a VGA port. In most other cases, you’ll need an adapter.

Here are the types of ports your laptop is likely to have and an explanation of the adapter you’ll need to obtain, if any:

  • HDMI Port : If your laptop has a full-sized HDMI port and your projector has the same type of port, you won’t need an adapter. HDMI is the easiest way to connect a projector to your laptop.
  • Mini HDMI Port : Also known as HDMI type-c, these are functionally identical to HDMI, just much smaller. You can use a cable with HDMI on one end and HDMI type-c on the other or an adapter.
  • DisplayPort : These are more commonly on desktop video cards, but your laptop may have one. If it does, then you can either use an HDMI-to-DisplayPort cable or an HDMI-to-DisplayPort adapter.
  • USB-C : If your laptop uses USB-C to output video, you’ll typically need to buy a dock that includes an HDMI port or a USB-C to HDMI adapter. Some projectors do support USB-C video input, though, in which case you can connect your laptop directly to the projector via a USB-C cable.
  • VGA : This is an older video connector that is limited to a resolution of 640x480. If your laptop and projector both have VGA ports, you can connect them with a VGA cable and no adapter. However, you will also need to use an alternate method to send sound from your laptop to the projector, as VGA does not transmit an audio signal the way HDMI does.

How to Use a Projector With a Laptop

To connect your laptop to a projector, you’ll need the laptop, the projector, a cable, and any necessary adapter, as outlined above. Once you’ve gathered all those items, here’s how to hook everything up:

Plug an HDMI cable, adapter, or VGA cable into your laptop and turn it on.

If using an adapter, also plug an HDMI cable into the adapter.

Jeremy Laukkonen / Lifewire 

Plug the other end of your cable into the projector.

Turn on the projector.

Remove the projector cap, and open the projector lens.

Your projector may not require this step. If the projector immediately projects an image on the wall after being turned on, you can skip this step.

Your projector is now ready to use, although additional configuration may be required.

If you haven’t set up your projector yet, the image may be blurry. Make sure the image is clear before you proceed.

Customize Your Projector Display From Your Laptop

While your projector should be ready to use, you may find it isn’t displaying the right image, the image is distorted, or it’s showing your main desktop when you want it to act as a separate display.

Here’s how to customize your projector display on Windows:

Check out how to connect a Mac to a projector for macOS-specific instructions.

Press Windows key + P to bring up the Windows projection menu.

Select the projection setting you prefer.

  • PC screen only : Your projector will not work.
  • Duplicate : Your projector will show the same thing as your laptop screen.
  • Extend : Your projector will act as a second monitor. You may need to change your display settings if the image is stretched or squashed.
  • Second screen only : Your laptop screen will shut off, and the projector image will act as your main screen.

Check to make sure the projected image looks right. If the projected image is stretched or squashed, click Start > Settings .

Select System on the left side, then select Display .

Select scale .

Adjust the scale until the projected image looks right.

You are now ready to use your projector as a secondary or mirrored display.

It might sound obvious, but check your cable connectors and adapters and make sure they're secure and in the right ports. If the cable looks worn or defective, try a different one. Also, make sure your laptop is set up to display on an external monitor.

First, set up your projector by finding a good location for your projector and screen. Then, connect all of your devices and power them up. Once everything is up and running, optimize your picture quality by setting a default aspect ratio, tweaking picture settings, and adjusting audio.

A short throw projector is generally one that casts its image three to eight feet away. The image is about 100 inches, where larger projectors typically create images of up to 300 inches. This makes it a good choice for smaller rooms that don't have a lot of screen space.

How to Project Screen in Windows 11

If you have connected more than one display, you can project the screen in Windows 11 in multiple ways. Here is how to do it.

For most laptop users, it is pretty normal to connect one or more displays to it. That way, they will have a bigger and more comfortable screen to work on. This is especially true when they are working at a desk. Often, the same is valid for desktop users. For example, the dual-display configuration is pretty popular among gamers, streamers, and productivity hunters.

Windows makes it pretty easy to connect multiple displays to the computer regardless of the use case.

That being said, when you connect a second display or projector, you might want Windows to behave in a certain way. For example, you might want to duplicate the main screen, use the second display as an extended screen, use only the second screen, etc. In my case, I close the laptop lid and use the second display as my main screen.

Thankfully, Windows has multiple Project modes to accommodate different use cases. All you have to do is select the Project mode, and you are good to go.

So, let me show you how to project the screen in Windows 11 and the project modes without further ado.

Table of contents:

Project modes in Windows 11

Project screen in windows 11.

Windows 11 offers four project modes. Depending on your use case, you can select the mode of your choice. Here are what those project modes are in Windows 11.

Duplicate these displays : As the name implies, selecting this option will duplicate whatever is on the main screen to the second screen. Put it simply; both screens show the same picture. For instance, if you connected a second display to the laptop and chose this option, you will see what is visible on the laptop screen. As you can guess, this mode is perfect for situations like presentations, seminars, etc.

Extend these displays : Selecting this option will extend the screen. If you need extra screen real estate or set up multiple monitors, you should choose this option.

PC screen only : If you only want to use the PC or primary screen and turn off the secondary screen, you can choose this option.

Second screen only : You should choose this option if you just want to use the secondary screen. As you can guess, most laptop users like to use this option.

There are two ways to project display Windows 11. i.e., you can do it from the Quick Settings panel or the Settings app. I will show both methods. Follow the one you are comfortable with.

Project Windows 11 screen from Quick Settings

Windows 11 Quick Settings panel will make it easy to project the screen with just a couple clicks. Here is how to do it in simple steps.

  • Connect the secondary display.
  • Click on the “Network” icon on the taskbar.
  • Click on the “Project” button.
  • Choose the “Project mode” of your choice.
  • Selecting the option will start projecting the screen.
  • With that, you are now projecting the display in Windows 11.
  • If needed, follow steps 2, 3, & 4 to change project mode.

Same steps with screenshots:

First, make sure the secondary display is connected to the computer. After that, click on the “Network” icon to open the Quick Settings panel. You can also open the same with the “Win + A” keyboard shortcut. After opening it, click on the “Project” button.

This action will show all the available project modes. Select the project mode of your choice to project screen in Windows 11. I’m selecting “Extend” option so that I can use Windows 11 in dual monitor setup.

select project mode in Windows 11

As soon as you select the option, Windows 11 will project the monitor according to the project mode you selected.

Troubleshooting: If you cannot find the “Project” option in Quick Settings, it might be hidden. To add it back, click on the “Edit” icon at the bottom of the Quick Settings panel, click “Add,” choose the “Project” option, and then press “Done.”

Project Windows 11 screen from Display Settings

You can project the screen from the Display options page in the Windows 11 Settings app. This method is helpful if the Quick Settings panel is not working for some reason or to access advanced display settings. Here is how to do it.

  • Open Settings from the Start menu.
  • Choose “System” on the sidebar.
  • Press the “Display” option on the main page.
  • Choose the project mode from the “Multiple displays” dropdown menu.
  • If needed, follow steps 2, 3, 4, & 5 to change project mode.

That is all. It is that simple to project a screen in Windows 11.

I hope this simple and easy Windows 11 how-to guide helped you.

If you are stuck or need some help, comment below, and I will try to help as much as possible.

How to Use a Laptop as a Second Display for Your Desktop

Laptop acting as second display for larger computer monitor

It's fairly standard practice to hook up a laptop to a larger display at home or at the office, but what's less common is to use a laptop as the second screen—even though it's not difficult to set up and can be just as much of a productivity boost.

If you have both a desktop computer and a laptop, you can use the laptop as a second display for the desktop. All the usual benefits of having two screens apply: More space for your apps, more windows and tabs open at once, and easier multitasking.

The only requirement is that the same operating system—Windows or macOS—must be running on both computers. This isn't something you can really do reliably and well with one machine running macOS and the other Windows, at least not right now or without third-party apps to do the work for you.

When it comes to using a Windows laptop as a second screen for a Windows desktop, the secret ingredient is the streaming standard Miracast, so no cables or connections of any kind are required. You're also going to need to have both your Windows desktop and your Windows laptop on the same Wi-Fi network, but that shouldn't be a problem.

You need to start on the laptop that you want to use as your second screen. Choose Settings from the Start menu, then pick System and Projecting to this PC . Under Some Windows and Android devices can project to this PC when you allow them to , choose the Available everywhere on secure networks option . This means you'll be able to see the laptop as a second monitor when you're on a secure network, like your home Wi-Fi.

Some preparation is required on your Windows laptop.

There are a few more options available here. You can decide whether a connection must be confirmed on the laptop every time you connect or just the first time, and you can set up a PIN to confirm the pairing process. You're also able to set up the feature so it's available only when your laptop is plugged in, and you can rename your laptop machine from here too, to make it easier to recognize on the network.

If you don't see these drop-down menus, you should see a prompt asking if you want to install the wireless projection feature: Just follow the prompts on screen to do this. The feature you want is labeled as Wireless Display and shouldn't take long to download and install. Once that's done, go back to the System and Projecting to this PC page, and the options we've mentioned above will then be visible.

Screenshot of Windows display settings

Finally, search for and run the Connect app on the laptop you want to connect to as a second display. Once that's done, you can turn your attention to the desktop that you're going to be projecting from. From Settings, choose System , Display , Multiple displays and Connect next to Connect to a wireless display . Pick your laptop when it appears in the list, and the connection is made.

You can access all of the usual settings for multiple displays under System and Display in the Windows Settings pane—so you can duplicate the two displays, or extend them so you've got twice as much room. Windows can be dragged between the two screens just as if you had an external monitor hooked up. On the secondary laptop, the second display runs in a window by default, but you can make it full screen if needed.

With macOS, you're also using a wireless streaming protocol, in this case AirPlay Display. It enables you to use a Mac or iPad as a second display, so it works with desktops and tablets made by Apple as well as laptops. It functions over both Wi-Fi and USB, so you can pick the wired or wireless solution that works best for your particular setup. You've got a lot of options to pick from.

The big prerequisite is that both Macs must be running macOS Monterey or later, to make sure you've got all the necessary technology built into the software. If that's the case, then your two Apple computers also both need to be online and signed into the same Apple ID account, which we're assuming is the setup that you're most likely to have.

Screenshot of MacOS display settings

AirPlay Display works as a native macOS feature.

AirPlay Display can be accessed from the Control Center up on the far right of the menu bar in macOS—the button looks like two toggle switches on top of each other. Open the Control Center on your desktop Mac, choose Screen Mirroring and if another compatible Mac is on the same network and running up-to-date software, you should see it as an option to connect to.

Another way to get to the same setting is to open the Apple menu in macOS on your main desktop Mac, then select Displays and click Add Display : Choose your MacBook from the list that appears, and the connection is made. It doesn't really matter which method you use, because the result will be the same.

Screenshot of MacOS display settings

macOS treats your MacBook as a genuine second display.

As is the case if you have an external monitor connected to your Mac, you're able to access scaling and other settings by going into Displays and then Display Settings from System Preferences . Windows can be easily dragged between your two screens, then arranged or made full-screen as necessary. It's just like using two monitors, though there may be a very slight lag over the Wi-Fi connection.

Open up Control Center again and choose Screen Mirroring , and you're able to switch between mirroring the displays (so both screens show the same content) and extending the displays (so using them as separate screens). If you have a Mac with a touch bar, these display options appear there as well. To break the connection, click the name of your MacBook Pro in the Control Center.

How to Switch from Your Laptop Screen to the Projector Screen

When your projector and computer are connected together and turned on, both of them should display the same image, whether it’s the desktop, application, or game playing on your PC. If you want to switch laptop screen to the projector screen , you’re actually curious about mirroring the desktop of your laptop screen unto the projector. However, there are times when the notebook or workstation PC will need manual mirroring. Many business projectors do this automatically, however. This is because they’re mainly made for presentations.

They work by toggling screen modes or mirroring the laptop or desktop PC’s screen as you open the slideshow app. You might also need to configure your computer in case the projector screen is using the wrong resolution or something.

Mirroring a Laptop or Desktop Display on Your Projector

Here are the things you need to keep in mind when switching from a laptop or desktop PC display to a projector display.

  • Older Windows Versions Require Projector Screen Switching: It was only recently that screen mirroring became the default option when running a projector with your laptop. The default used to be that there’s no picture on your laptop (it also happened on desktop PCs, by the way). Windows in the 1990s and early 2000s don’t feed images to the screen and video out ports at the same time, so your projector is now your screen. This necessitated screen switches.
  • Hotkey Toggling Between Projector Modes: You can use hotkeys in order to toggle between different projector modes as you go about your presentation and whatnot. Here, you can switch between projector and laptop screen, mirror or duplicate the screen between the two, or extend your desktop to the projected image.
  • How to Use Hotkeys to Toggle or Duplicate The Screen: On your keyboard, hold down the Windows Key then press P to bring up the projector screen. You can instead click “Duplicate” to share the image on your computer screen to the projector, thus mirroring the display. You can click “Extend” to extend the image to your projector as well.
  • Mirrored Display: A mirrored display allows you to play different apps you’d normally access through your computer. Your physical connection can either be HDMI , VGA , DisplayPort, Thunderbolt and so forth. Mostly VGA though since HDMI is a more recent A/V standard from 2002 onwards.
  • Mirrored Displays and Establishing The Physical Connection: If you’re using a modern-day business projector then it’s usually enough to properly connect it to your laptop to mirror their displays automatically. This is because the latest business projectors are supposed to mirror your whole screen, operating system, desktop user interface, and the like instead of merely playing a video or a videogame.
  • Plug & Play: Ever since the 1980s and especially the 1990s, many devices such as projectors were plug & play or automatically recognized by the system, ready to use and mirror your screen. You don’t need to restart your computer or install drivers (or the drivers will be installed for you by the OS through the Internet).
  • Hold The Function Key: If you don’t want to tinker with your configurations, many laptops can switch to the projector by holding down the Function Key or “Fn” on the bottom left of your keyboard and then pressing the button with two monitors on them (usually the F7 or F8 Key, but it varies).
  • Go to Settings: If you still can’t switch to your VGA/HDMI port to start screen duplication or mirroring then you’ll have to go to your settings by right-clicking your desktop and picking the screen resolutions window to either mirror or duplicate your screen when all is said and done. The details on how this is done are outlined below.
  • Windows-Based Computers and Mirroring: Windows makes it easy to configure your projector to mirror your onscreen desktop of your PC or laptop. It ranges from being able to recognize the display device once connected and turned on to manually adjusting settings to allow mirroring. Some Windows operating systems have various display options you have to configure in order to get the mirroring or switching you wish to achieve.
  • Screen Resolution : Go to the virtual desktop of your PC and then right click on the wallpaper. You should get a dropdown menu wherein you can select the “Screen Resolution” option. It controls not only resolution but screen mirroring and other screens (or projectors) connected to your notebook PC.
  • Multiple Displays: From the “Multiple Displays” dropdown box on the ensuing window, choose the “Duplicate These Displays” option. Don’t choose the “Extend These Displays” option, that’s for extended displays on multiple monitors. From there, save the settings and exit the window.
  • Why The Manual Configuration? Your settings or your computer might not recognize the right resolution or display type for your projector, resulting in an “Extended Display” that you can sometimes do with two or more monitors.
  • Apple/iOS Computers and Mirroring:  As for iOS devices and Apple computers, you need to remember the following points. First off, the computer and the projector should be properly connected, whether it’s via HDMI or wireless HDMI as well as Thunderbolt, Lightning, and the like. It depends on your MacBook laptop or Macintosh PC.
  • Ensure Compatibility: As a rule of thumb, use a compatible projector that matches the make, model, and year of your iOS device. Otherwise, you’ll have to tinker with adapters to make things work.
  • Small Monitor Icon: Your Mac or iOS device should detect the projector if it has the right connection via a small monitor at the top of its screen. Click this icon then choose the “Open Display Preferences” selection.
  • Display Preferences Window: Once you get to the Display Preferences window, go for the box named “Mirror Displays” and click it. Now you can mirror your display on your projector.
  • Windows 10 Wireless Mirroring Configuration: If you wish to configure Windows 10 for wireless mirroring, here’s what you need to do. Select the Screen Mirroring Settings on your projector if available. Afterwards, press the LAN button on your projector remote control in order to switch to the Screen Mirroring source. This will prompt the Screen Mirroring Standby Screen.
  • What To Do on The Screen Mirroring Standby Screen: Once you’ve accessed this particular screen, go ahead and select Apps, select Settings, select Devices, select Connected Devices, and then click the Add a Device option. A list of available devices will be presented to you.
  • Pick Your Projector off The List and Enter the PIN Code: On the list, select your specific projector. If your laptop has a PIN entry screen as well, enter the PIN code on the bottom right of the projected image or the Screen Mirroring standby screen then click the “Next” button. This should result in the projector displaying the image from your laptop wirelessly.
  • Be Patient and Don’t Disconnect: When establishing a wireless connection between your laptop and your projector, it might take a bit of time. Don’t disconnect your projector’s power cord while it’s synchronizing its link with your notebook PC. This might make your computer hang or freeze.
  • Mirroring Your Mac Screen Wirelessly with Airplay: You need to activate Airplay or AirPlay for the sake of mirroring your Mac screen on a projector. It broadcasts or streamcasts the signal to any Apple-compatible display device, like a projector or an Apple TV. The Airplay icon is available on the top-right corner of your screen, at the so-called menu bar. Enable your Airplay button in case you don’t see it on the screen.
  • Select the Device: As long as you’re assuredly using a compatible projector for your MacBook Pro or Air, it should be on the list of selectable devices you can broadcast to using Airplay. Otherwise, you might need to connect your projector to an Apple TV via wired HDMI connection to make it serve as your screen mirroring middleman.
  • Enter The Code: You might be prompted to enter the code from your Apple TV or projector display. Input the code in the window that appears on your Mac notebook PC to establish your wireless connection. When everything is said and done, this should result in your MacBook screen being mirrored by your projector (with or without the assistance of the Apple TV).
  • Settings and Proportion Adjustment: You can better configure the resulting projector image by accessing the Airplay button on your menu bar once again. There, you can click the “Mirror Built-In Display” to have your Apple TV match the proportions of your MacBook. You can also click “Mirror Apple TV” to have the display on your Mac mirror your Apple TV and projector as well.

In a Nutshell

Switching your laptop screen to your projector screen can be done in a multitude of ways. It can be as simple as connecting your projector to your laptop (especially if it’s a business projector made after 2010 or so) and as complicated as fiddling with your screen configurations or settings in order to select the screen duplication or mirroring option. However, you usually can’t switch from laptop to projector and back. Usually, both screens are mirrored with each other, with the projector duplicating the screen shown on your laptop

Connecting an external monitor to your PC or Mac laptop is pretty easy. You'll just need to find out what type of output your laptop has, such as HDMI, Thunderbolt, or USB-C. Once connected, you can use both screens at the same time or close your laptop to use the monitor like a desktop computer. This wikiHow article will show you how to find out what cable you'll need to connect your laptop to a monitor, and how to set up your second monitor to mirror or extend your laptop's main screen.

Connecting a PC Laptop to a Monitor

Step 1 Determine your laptop's video output options.

  • HDMI : This is a 6-sided trapezoid-shaped port that's about ¾ of an inch wide.
  • DisplayPort: The size is similar to HDMI, but one of the corners is bent inward while the other forms a 90-degree angle.
  • If you see a lightning bolt with an arrow at the bottom next to the port, the port supports Thunderbolt 3, and you can use a USB-C or Thunderbolt 3-compatible monitor.
  • If you see an icon of a black "D" with a white "P" inside, the port supports DisplayPort, which means you can use a USB-C or DisplayPort-compatible monitor.
  • VGA or DVI: Less common nowadays are VGA ports, which are 15-holed ports with two pins on either side, and DVI ports, which have 24 holes and a gap on one side.

Step 2 Determine your monitor's video input.

  • Once connected, you should see your laptop's desktop and icons (or some variation thereof) appear on the monitor's screen, you can proceed with setting up your laptop's display settings.
  • If you are using a monitor or TV that has multiple inputs, you will need to select the port you connected your laptop to on the monitor.

Using Both Screens on a PC Laptop

Step 1 Open your Windows Settings icon.

  • If you're on Windows 10, click the drop-down menu under "Multiple Displays." On Windows 11, click the drop-down menu to the right of the "Identify" button.
  • Select Duplicate these displays if you want to see the same exact thing on both screens at the same time.
  • Select Extend these displays if you want to use the second monitor as a continuation of your desktop space. This lets you drag windows between screens.
  • Select Show only on 1 if you want to use the monitor labeled "1" as your only monitor. This is your laptop's built-in screen. Choosing this will turn off the external monitor.
  • Select Show only on 2 to only show your laptop's contents on the monitor that's labeled "2," which is the external monitor. This turns off your laptop's built-in screen as long as the external monitor is connected.

Step 5 Choose a main display.

  • Click the Identify button to display each monitor's number each screen it's assigned to.
  • Click the display you want to make your main display.
  • Select Make this my main display under "Multiple displays."

Step 6 Rearrange your screens.

  • If you're extending your desktop, you can test the new setup by moving your mouse in the direction of the other monitor—the cursor will appear on the other screen when moved in the right direction.

Using Your PC Laptop with the Lid Closed

Step 1 Connect a keyboard and mouse to your laptop.

  • If you choose this option for "On battery," the second monitor will stay on even if you close the laptop if you're not plugged in. This could drastically decrease the life of your battery, so it's not recommended.

Step 8 Click Save changes.

Connecting a MacBook to a Monitor

Step 1 Find your MacBook's video output.

  • Thunderbolt 3, Thunderbolt 4, and Thunderbolt USB 4: An oval port with a lightning bolt, found on all MacBook Pros beginning in 2016, and MacBook Airs beginning in 2018. [10] X Research source
  • USB-C : An oval port without a lightning bolt icon. 12" MacBook Pros from 2015, 2016, and 2017 have these. [11] X Research source
  • HDMI: A six-sided tapered port found on 2021 MacBook Pros, as well as MacBook Pros from 2012 to 2015. [12] X Research source
  • Thunderbolt 1, Thunderbolt 2, or Mini DisplayPort: The original Thunderbolt ports both have 6 sides and are not oval-shaped. You'll see a lightning bolt icon near this port on MacBook Air models from 2011-2017, and MacBook Pros from 2011-2015. On MacBook Pro and Air models made between 2008 and 2010, you'll see a square with two vertical lines instead.
  • If you're not sure which port you can use for a monitor, go to https://support.apple.com/specs , select your model, and find the ports under "Charging and Expansion."

Step 2 Find your monitor's video input.

  • Nearly all modern Apple monitors will work with Thunderbolt 3, 4, USB 4, and USB-C. Most of these monitors come with a cable that will fit into these ports and work immediately.
  • Many non-Apple monitors also support Thunderbolt 3, Thunderbolt 4, USB 4, USB-C, and HDMI.

Step 3 Get a cable and an adapter if necessary.

  • MacBooks with Thunderbolt 4: Use a Thunderbolt 4, Thunderbolt 3, or USB-C cable to connect to any of these types of monitors. You can also use an adapter to connect to a DVI, HDMI, or VGA monitor.
  • MacBooks with Thunderbolt 3 and Thunderbolt USB 4: Use a Thunderbolt 3 or USB-C cable to connect to either of these monitor types. You can also use an adapter to connect to a DVI, HDMI, or VGA monitor.
  • MacBooks with USB-C: Use a USB-C cable to connect to a USB-C monitor. You can also use an adapter to connect to a DVI, HDMI, or VGA monitor.
  • MacBooks with Thunderbolt 1, Thunderbolt 2, and Mini DisplayPort : Use a Mini DisplayPort cable to connect to Mini DisplayPort monitor, or an adapter to DVI, HDMI, or VGA monitors.

Step 4 Use the cable to connect your laptop to the monitor.

  • If you are using a monitor or TV that has multiple inputs, you may need to select the port you connected your laptop to on the monitor. Press the button that says "Input", "Source". or "Video Select" or something similar on the monitor or remote.
  • If you don't see your MacBook's screen on your monitor, you may need to detect the display. On your MacBook, click the Apple menu, select System Preferences , click Displays , and then click Detect Displays . [14] X Research source

Using Both Screens on a MacBook

Step 1 Open your Mac's System Preferences….

  • If your plan is to close the laptop and use the second monitor as your only monitor, mirroring is the option you'll want.

Step 5 Choose the primary monitor.

  • If you want your external monitor to be the primary monitor, click and hold the white bar with the mouse, and then drag it to the other monitor. The menu bar will only appear on the primary display.
  • If you want to keep your laptop as your primary monitor, you don't have to change anything here.

Step 6 Rearrange the screens (optional).

  • This makes it so you can easily drag a window from one monitor to another without having to guess which direction to drag it in.

Using Your MacBook with the Lid Closed

Step 1 Connect a keyboard...

  • This is also called "closed lid mode" or "closed clamshell mode."

Step 3 Turn on screen mirroring.

  • Click the Apple menu and select System Preferences .
  • Click the Arrangement tab.
  • Check the box next to "Mirror Displays."

Step 4 Adjust your energy saving settings.

  • Click Battery .
  • Drag the slider at the top all the way to the right (to "Never").

Step 5 Close the lid of your MacBook.

How to use split screen in Windows 10 and 11

W orking with multiple apps simultaneously can be time-consuming and inconvenient at times. Thankfully, Microsoft offers several ways to organize apps on the desktop. The software giant has already delivered a robust multitasking experience on Windows 10, and with Snap assist on Windows 11 , Microsoft took it to the next level. Whether you work on a laptop, or monitor or have a multi-screen setup, here’s how to use split screen on Windows.

Unlike macOS, you don’t need to use third-party apps to view apps side-by-side on Windows. The feature is built right into the OS. Snap assist isn’t entirely new, though. It has been available since Windows 7 days. However, the feature was limited to snapping only two windows side by side. Windows 10 improved the support for up to four apps, and Windows 11 takes it even further with snap layouts and app suggestions.

Method 1: Arrange apps using Snap Assist

Snap Assist offers one of the effective ways to enable split screen on Windows 10 and 11. Let’s check it in action.

  • When a bunch of app windows are open, select an app you want to arrange on the screen. Click on the title bar and move it left or right until you see a blank window taking up half the screen. Release your fingers from the trackpad or mouse.
  • Check the other half of the display with your opened apps. Select an app window to enable a split screen.
  • Move the cursor right in the middle and check the vertical bar . Select and move it to the left or right to resize the window.
  • Based on your monitor size and display resolution, you can also snap three or four app windows side by side. Select the title bar on an app window and drag it to the top/bottom right or left corner. Release your mouse.
  • Repeat the same for other opened apps and drop them to other corners of your screen.

While the trick above gets the job done, it’s not the most user-friendly way to split screen on Windows. Instead, we recommend using keyboard shortcuts to split app windows on the desktop.

Method 2: Use keyboard shortcuts to split screen in Windows

If you don’t want to deal with the drag-and-drop method, mesmerize keyboard shortcuts to snap app windows in no time.

  • Keep an app window in focus and press Windows + left/right arrow keys to pin it on the left or right side of the screen.
  • Check app suggestions on the other side and use the arrow keys to switch between them. Hit enter and check the split screen in action.
  • You can also snap three or four app windows using the keyboard shortcuts. Select an app and press the usual Windows + left/right arrow keys . Then, press Windows + up/down arrow keys to pin at the top or bottom corner.
  • Check the display thumbnail for other apps and click on it to arrange them.
  • Once all four app windows are open, select an app and press Windows + left/right keys to move it to the left or right side.

As always, you can move the cursor over the thin separator between apps and resize the app window to your preference. Once you get used to keyboard shortcuts, you won’t return to the usual drag-and-drop method. This one is quicker and much better than the traditional method.

Method 3: Snap Layouts and Snap Groups in Windows 11

Microsoft has fixed many Windows 10 shortcomings with the Windows 11 update. The company has introduced Snap Layouts and Snap Groups, which are built on top of Snap Assist, giving you a new way to use split screen.

  • Open an app on the desktop and hover the cursor over the maximize icon. The system shows ready-to-use snap layouts.
  • Select a relevant option to arrange the current app window.
  • Check app suggestions for other layouts and click on a relevant window to place it side by side.

You can also drag an app window and move it to the top of the screen. You should notice snap layouts appearing at the top. Drop the app window to a relevant location and add another app in the split view.

Windows 11 also comes with another neat add-on called Snap Groups. It remembers and saves your snap layouts. You can open all your apps in your preferred layout with a single click only. Go over our separate guide to learn more about Snap Groups .

What to do if these options aren't available

If you're not seeing the options above, you may have disabled multi-tasking features in Windows 11. Here's how to re-enable them:

  • Hit the Windows + I keys to open Settings. Select System from the side menu.
  • Scroll to Multi-tasking .
  • Enable the Snap windows toggle and expand it.
  • Enable the checkmark beside all the options.

Now, you are all set to use Snap Layouts on Windows 11.

Get work done in style

If you want more control over your active apps, use FancyZones from PowerToys. It's basically a Snap assist on steroids and offers preset layouts, better customization and more. Developed by Microsoft, PowerToys carries a bunch of tools to elevate your Windows setup. You can check our dedicated guide to learn our top five PowerToys features . Hopefully, Microsoft will implement some of them in the upcoming Windows 12 .

Google’s Gemini is now in everything. Here’s how you can try it out.

Gmail, Docs, and more will now come with Gemini baked in. But Europeans will have to wait before they can download the app.

  • Will Douglas Heaven archive page

In the biggest mass-market AI launch yet, Google is rolling out Gemini , its family of large language models, across almost all its products, from Android to the iOS Google app to Gmail to Docs and more. You can also now get your hands on Gemini Ultra, the most powerful version of the model, for the first time.  

With this launch, Google is sunsetting Bard , the company's answer to ChatGPT. Bard, which has been powered by a version of Gemini since December, will now be known as Gemini too.  

ChatGPT , released by Microsoft-backed OpenAI just 14 months ago, changed people’s expectations of what computers could do. Google, which has been racing to catch up ever since, unveiled its Gemini family of models in December. They are multimodal large language models that can interact with you via voice, image, and text. Google claimed that its own benchmarking showed that Gemini could outperform OpenAI's multimodal model, GPT-4, on a range of standard tests. But the margins were slim. 

By baking Gemini into its ubiquitous products, Google is hoping to make up lost ground. “Every launch is big, but this one is the biggest yet,” Sissie Hsiao, Google vice president and general manager of Google Assistant and Bard (now Gemini), said in a press conference yesterday. “We think this is one of the most profound ways that we’re going to advance our company’s mission.”

But some will have to wait longer than others to play with Google’s new toys. The company has announced rollouts in the US and East Asia but said nothing about when the Android and iOS apps will come to the UK or the rest of Europe. This may be because the company is waiting for the EU’s new AI Act to be set in stone, says Dragoș Tudorache, a Romanian politician and member of the European Parliament, who was a key negotiator on the law.

“We’re working with local regulators to make sure that we’re abiding by local regime requirements before we can expand,” Hsiao said. “Rest assured, we are absolutely working on it and I hope we’ll be able to announce expansion very, very soon.”

How can you get it? Gemini Pro, Google’s middle-tier model that has been available via Bard since December, will continue to be available for free on the web at gemini.google.com (rather than bard.google.com). But now there is a mobile app as well.

If you have an Android device, you can either download the Gemini app or opt in to an upgrade in Google Assistant. This will let you call up Gemini in the same way that you use Google Assistant: by pressing the power button, swiping from the corner of the screen, or saying “Hey, Google!” iOS users can download the Google app, which will now include Gemini.

Gemini will pop up as an overlay on your screen, where you can ask it questions or give it instructions about whatever’s on your phone at the time, such as summarizing an article or generating a caption for a photo.  

Finally, Google is launching a paid-for service called Gemini Advanced. This comes bundled in a subscription costing $19.99 a month that the company is calling the Google One Premium AI Plan. It combines the perks of the existing Google One Premium Plan, such as 2TB of extra storage, with access to Google's most powerful model, Gemini Ultra, for the first time. This will compete with OpenAI’s paid-for service, ChatGPT Plus, which buys you access to the more powerful GPT-4 (rather than the default GPT-3.5) for $20 a month.

At some point soon (Google didn't say exactly when) this subscription will also unlock Gemini across Google’s Workspace apps like Docs, Sheets, and Slides, where it works as a smart assistant similar to the GPT-4-powered Copilot that Microsoft is trialing in Office 365.

When can you get it? The free Gemini app (powered by Gemini Pro) is available from today in English in the US. Starting next week, you’ll be able to access it across the Asia Pacific region in English and in Japanese and Korean. But there is no word on when the app will come to the UK, countries in the EU, or Switzerland.

Gemini Advanced (the paid-for service that gives access to Gemini Ultra) is available in English in more than 150 countries, including the UK and EU (but not France). Google says it is analyzing local requirements and fine-tuning Gemini for cultural nuance in different countries. But the company promises that more languages and regions are coming.

What can you do with it? Google says it has developed its Gemini products with the help of more than 100 testers and power users. At the press conference yesterday, Google execs outlined a handful of use cases, such as getting Gemini to help write a cover letter for a job application. “This can help you come across as more professional and increase your relevance to recruiters,” said Google’s vice president for product management, Kristina Behr.

Or you could take a picture of your flat tire and ask Gemini how to fix it. A more elaborate example involved Gemini managing a snack rota for the parents of kids on a soccer team. Gemini would come up with a schedule for who should bring snacks and when, help you email other parents, and then field their replies. In future versions, Gemini will be able to draw on data in your Google Drive that could help manage carpooling around game schedules, Behr said.   

But we should expect people to come up with a lot more uses themselves. “I’m really excited to see how people around the world are going to push the envelope on this AI,” Hsaio said.

Is it safe? Google has been working hard to make sure its products are safe to use. But no amount of testing can anticipate all the ways that tech will get used and misused once it is released. In the last few months, Meta saw people use its image-making app to produce pictures of Mickey Mouse with guns and SpongeBob SquarePants flying a jet into two towers. Others used Microsoft’s image-making software to create fake pornographic images of Taylor Swift .

The AI Act aims to mitigate some—but not all—of these problems. For example, it requires the makers of powerful AI like Gemini to build in safeguards, such as watermarking for generated images and steps to avoid reproducing copyrighted material. Google says that all images generated by its products will include its SynthID watermarks. 

Like most companies, Google was knocked onto the back foot when ChatGPT arrived. Microsoft’s partnership with OpenAI has given it a boost over its old rival. But with Gemini, Google has come back strong: this is the slickest packaging of this generation’s tech yet.

  • Thursday at 12:07 PM

I don't watch tv but my Thai wife does and when our tv broke down she was really upset. We won't have funds to replace it for some time so as we got wi-fi and a laptop each it seemed good for her to download OBS and use a hdmi cable and usb adapter plugged into the cable box and watch on the laptop. So following sundry YouTube vids she downloaded OBS and installed it but she is not a native English speaker and the various instructions on the how-to vids fail to tell her how to get away from the silly little screen picture and go full screen. I am no help in this respect as it is outside my expertise too. So please folks - can someone give chapter and verse for idiots to make the tv pictures full screen so she can watch?
