How can I fix my Switch's resolution in docked mode?
Solution 1:
Have you tried manually changing the screen size via TV Settings?
- From the HOME Menu, select "System Settings."
- Scroll down the menu on the left-hand side of the screen and select "TV Settings."
- Select Adjust Screen Size. (Dock the console and follow the on-screen prompts to manually adjust the screen size)
Additionally, changing the TV Resolution here may also help.
