Settings > Display type -- set it to your set's actual display resolution, not the auto setting.
When you change the Display type to a new setting it runs you through a several screens:
- A screen where you can choose from the available options on that device.
- A screen where it analyzes your choice to be sure your tv supports it, then gives the option of going to that choice if you wish.
- A screen with a countdown timer and two choices:
Yes, screen looks good
No, I will choose a different setting
The "No" option is highlighted by default. To keep the screen resolution you have chosen, you need to arrow up to the "Yes" option and click on it before the timer runs out.
