When I'm using my Nintendo Switch console in TV mode, the display doesn't match the size of the TV screen.

Applies to: Nintendo Switch

You can adjust the TV display size by going to the HOME Menu and opening System Settings ⇒ TV Output ⇒ Adjust Screen Size.

If you set the screen size to 100% and the display is still smaller than the TV screen, please check the screen settings on the TV itself.
