A number appears on the screen of the display it's assigned to. Select Settings > System > Display > Identify. To see which number corresponds to a display, select Start, then type settings. Each display will be numbered to help you identify them more easily. You'll see this option when Windows detects more than one display. After connecting your wireless display adapter to your TV, go to your Windows 11 PC, press Windows logo key + K to open Cast, then select your wireless display adapter. Tip: If you're using a wireless display adapter, connect to an HDMI port on newer TVs, then wirelessly connect your PC to it.
