There are many ways to connect your Windows 11 computer screen to other devices. But now that Miracast is available, it’s never been easier to send your computer’s screen to a smart TV. As long as the technology is built into Windows 11, you don’t have to download and install the app on your own. As long as you have a TV or projector that can show your computer screen, you can wirelessly project your screen there from your computer.
There are a lot of steps in this guide that we’ll show you with screenshots and step-by-step instructions. We’ll show you how to check for Miracast support, set up a wireless connection, and share your Windows 11 desktop screen with other devices.
How to Find Out if Your Windows 11 PC Can Use Miracast
1. Press the Windows Key + P to check.
You can find out quickly if you can share your screen wirelessly this way. Here, we use the projection screen to see if it is possible.
Press the Windows key and P at the same time to open up the projection options in the Windows menu bar.
If you can see 4 different ways to project your screen, it’s very likely that your computer will be able to share your screen wirelessly. Use the next method to see if this is true.
2. Check the Display Settings.
Go to Settings and then Display. Alternatively, you can just click here: Open the Display Settings.
Then, in the Multiple Displays section, see if there’s an option to connect to a wireless screen there. Your computer may be able to screencast using Miracast if it’s available.
3. Check with the DirectX Diagnostic Tool.
This is a more complicated way to find out if your computer can use Miracast. In this case, we are going to use the DirectX Diagnostic Tool to do this.
To open the Run dialogue, press the Windows key and R on your keyboard to get to the Start menu.
Then, type in dxdiag and hit OK to start the process.
In the Diagnostic Tool window, click on the Save All Information button at the bottom to save all of the information.
Choose your Desktop (where you can find the file quickly) as the location and click Save.
Now, go to the desktop and open the file that we’ve just saved, then click on it (DxDiag).
You can look for Miracast in the System Information.
If your computer can handle it, you can see things like this:
Miracast: You can use it with HDCP. It will say “Not Available” if it doesn’t.
In the end, you can delete the DxDiag file.
Check to see if your TV can use Miracast.
To be able to show Windows 11 on the TV, your TV must also be able to connect to the Internet. To see if this is true, we have a few ways to do it.
1. Make sure that your TV settings are correct before you go to sleep at night.
To see if your TV can connect to the internet, look in the TV settings. To do so, follow these steps.
The following TV-related descriptions are only for reference, because the functions of TVs can be different based on the make and model of the TVs you have.
You may be able to find the screen sharing option right away in the settings. Wired display, screen casting, Miracast, Wi-Fi casting, and screen mirroring are all names for this.
If you can’t find it right away, press the Menu button on your TV remote and choose Apps. Then, look for apps that are labelled the way that was above.
In some smart TVs, casting is thought of as a separate input instead of an app, so it’s not the same thing. Choose “Miracast,” “Screen Casting,” or “Screen Mirroring” on your TV remote and then press the Input or Source button on your remote to find and press it.
TVs come in different models, and the buttons and labels on each one may be different as well.
This means that if you didn’t find anything like the steps above on your TV, then it may not be able to use wireless display. To make sure, follow the steps below.
2. Check the Miracast-Supported Devices List to see if your device is on it.
You can see it on the official website of the WiFi Alliance, which is in charge of making sure TVs and other devices can use Miracast.
If you know the brand and model of your smart TV, you can check it against the list of devices that are compatible with it here.
There should be no problems with Miracast now that you’ve checked that it works on both of your Windows 11 PC and your Smart TV. If you found that both of your devices worked well, there’s one more thing you need to think about.
It doesn’t mean that even though your computer and TV both have screencasting technology, you won’t be able to connect them while you try. The Miracast Windows 11 drivers may need to be updated in order for it to work for you.
To be able to connect wirelessly and cast, the system must have the Windows Display Driver Model (WDDM) 1.3 or later. Getting a driver updater tool from a third-party company is the easiest way to make sure your drivers are up to date. To do this, follow the steps below.
Update the Miracast drivers on Windows 11
Download and set up the DriverFix app.
Open the programme and let it find the old or broken drivers for you.
It will show up a list of things that need to be done. Choose the drivers that you need to fix or upgrade from that list.
It will take time for the programme to update and finish the process. If everything is done, restart your computer to see the changes.
Note: For some things to work, you may need to move from the free version to the paid ones.
How to Connect Windows 11 to a Smart TV.
You can wirelessly project your screen from your computer to your TV if both your computer and TV support Miracast. These steps show you how.
The first thing you need to do is install a small app on Windows 11 to make the wireless display feature work. To do this, go to Settings > Apps > Extra features. Or you can just click here [Open Optional features].
Now, click on the View features button next to Add an optional feature and type “wireless display” into the search box (make sure that you are connected to internet).
If you check the box, click Next, and then Install, the app will show up.
Putting the feature on your computer may take a long time. Once you’re done, close the setting.
Now, turn on your TV’s wireless display (or something similar) mode.
To open the screen casting options on your computer, press the Windows key and K on your computer at the same time. Windows will automatically look for devices that can be used for casting.
The name of your TV will show up if everything is good. You may need to click on it to get connected to the TV. When you connect, your screen will be shared right away:
What if Your TV Doesn’t Work with Miracast?
Your best bet is to buy a Miracast adapter for your TV, even if your TV doesn’t have wireless technology built into it. An HDMI port on the TV can be used to connect the adapter to your computer and TV so that you can communicate with each other wirelessly.
You might not be able to use Miracast if your computer does not.
If your computer doesn’t support it, then you may need to use the Actiontec ScreenBeam USB Transmitter dongle to send the video. It can let you use a wireless display on your computer if they don’t already have one.
When you want to show a picture from Windows 11 to a Smart TV, it’s simple to do.
Now that you know how to check if your computer has screencasting support and how to wirelessly stream your computer screen to your TV, you should be able to do these things. Miracast must be built into your computer if your computer came with Windows 11. You might not have it if you’ve upgraded from Windows 7, but it’s more than likely that you will. However, if you follow the steps, you can quickly find any problems with the connection and cast your screen with ease. So, make the most of the feature and use it to its fullest.
