To show the webcam image full screen on a TV, the supported path in the available guidance is to use the TV as a second display through a Microsoft Wireless Display Adapter, then adjust the display resolution and scaling if the picture does not fill the screen.
- Connect the PC to the TV or projector through the Microsoft Wireless Display Adapter.
- If the image is not filling the TV correctly, on the PC select Search on the taskbar, enter screen resolution, then select Change resolution of the display.
- For Display resolution, select the resolution marked Recommended.
- Select Apply.
- If parts of the image are still missing or not scaled correctly, open the Microsoft Wireless Display Adapter app.
- Select Personalization.
- In Fit to Display, drag the slider to the right until everything on the PC display fits correctly on the TV.
If video is frozen on the TV, disconnect and reconnect the adapter:
- Open action center.
- Select Connect > the adapter name > Disconnect.
- Unplug both ends of the adapter from the display and plug them in again.
- Open action center > Connect, then reconnect to the adapter.
If the TV supports less than 1080p, the PC will default to that lower resolution while connected.
