A:
If you're getting black bars on the side of the screen, it's likely that rather than adjusting the monitor, you should be adjusting your resolution on the video card. Often times, some resolutions have different aspect ratios, and putting the wrong resolution/aspect combination can result in black bars. Black bars are not recommended, so we do suggest changing the resolution so that the picture fills the screen.
A list of recommended resolutions is included in the manual.
Thanks for your interest in Samsung products.
