    Miracast connection problems on the wireless screen

    In case of problems, if using the Project key you cannot find the wireless display to connect, then you can go to the Windows 10 settings, to section devices. Under Bluetooth and other devices, click on Add Bluetooth or other device and then, in the window that follows, click on Wireless Display or Dock.

    If still nothing is detected or if the connection to the screen does not work, then you need 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.

    Check if your PC supports Miracast

Here, go to the page dedicated to the screen, look to the right under Driver and look for the Driver Model line: If it is written WDDM 1.3 or higher then it is fine, otherwise the system is not compatible with a Miracast connection.
    Also, still from DXDiag, then press the Save all information button and save the DxDiag.txt file in a folder or on the desktop.
