How to not have horizontal black lines at top and bottom of screen
When watching some movies, thick horizontal lines are at the top and bottom of the screen. Will this cause burn-in? How can I avoid this?
Black bars on the top and bottom appear when movies that are playing on your TV have aspect ratios different from your TV. So try changing your aspect ratio. Also, it will not cause image retention because the black area are not emitting any light through them. Image retention is only caused by static images emitted continuously for a long time.
