Project Windows 11 on TV

Cast screen To project the Windows 11 desktop on any Miracast compatible Smart TV, make sure that the computer and the TV are connected to the same network (or better to the same modem).

After carrying out this check, press at the bottom right on one of the system icons (for example volume), press on Transmit and select the Smart TV in our possession to start the transmission. To be safe, we confirm the connection on the TV or follow the onscreen instructions to project the Windows 11 desktop onto the wireless TV.

To change the type of projection we press again on one of the system keys at the bottom right, this time we press on the key Project and choose your preferred type of projection among duplicate (the same desktop between PC and TV) e I extended (to get two separate desktops).

Project Windows 10 on the TV screen

Desktop Windows 10 To project the Windows 10 desktop, the procedure is very similar to that seen for Windows 11, but some keys and the path to be used change.

To proceed we will have to press at the bottom right on the notification center, press on Expand (if present), click on Connect and press on the name of the Smart TV in our possession. After passing the checks we will see the Windows 10 desktop appear on the TV and we can choose the type of projection using the same key seen on Windows 11 (i.e. Projectpresent in the notification center).

Troubleshoot the wireless display

In case of problems, if using the Project key you cannot find the wireless display to connect, then you can go to the Settingsto section Bluetooth and Devices (o Devices on Windows 10) and press on Add device and select the item for wireless displays.

The search should detect the presence of a Miracast-supported device, which you can use to project Windows 10 to your TV or other wireless monitor.

If still nothing is detected or if the connection to the screen does not work, then you have to check if your PC supports Miracast. There is in fact the possibility that the PC is too old and lacks this function or that it is the fault of the video card driver, not updated.

To check that the PC supports Miracast, press the keys together on the keyboard Windows – R to bring up the box and type PowerShell (or look for PowerShell on the Start menu and start it).

In PowerShell we type the command:

Get-netadapter|select Name, ndisversion

After launching the command we check if the item Wi-Fi shows a value 6.40 or higherthen it’s okay, otherwise, if there is a lower value, Miracast is not supported by the PC.

To check that the video card supports Miracast we open the start menu and search dxdiag to open the DirectX diagnostics page; now we open the page dedicated to screenlet’s look right below Driver and look for the row Driver Model.

If we find the voice WDDM 1.3 or higher we enjoy Miracast support, otherwise the system is not compatible with wireless displays. Also, still from DXDiag, then press the key Save all information and save the DxDiag.txt file in a folder or on the desktop.

Open the generated text file and search within the line Miracast; if it is written Available, with HDCPthen it’s okay, if it says it Not Available then the computer does not support Miracast and there is not much to do.

How to reset the wireless screen

To restore the functioning of the wireless screen it is worthwhile update or reinstall network drivers and video card drivers.

To do this you can open, by pressing the right mouse button on the Start button at the bottom left, the Device management; in the new screen we click on Network cards e Video cardspress the right button on the active Wi-Fi card and on the video card and press on Uninstall device.

After the uninstallation, we restart the PC to activate the generic drivers and proceed with the update of the video card driver and network card drivers: for convenience we can use Driver Booster to automatically download updated drivers for our peripherals.


In case the TV does not have Miracast support we can always use Google Chrome and a Google Chromecast connected to the TV to activate the wireless screen, as seen in our guide on how configure wireless secondary display on PC.

Another valid substitute is the Fire TV Stick, which supports Miracast very well; if interested we can read our guides on how to cast screen on Amazon Fire TV Stick and you have best tips and tricks for the Fire TV.
