Black border on full screen gaming/benchmarks

[slyu9213]

Okay so I have an issue where if I try to play on the native resolution (1080p) on the TV there is a black border around the screen. With any lower resolutions like 1600x900 it will stretch/fit the full screen. This also happens to one of the odd resolutions which is between 1600x900 and 1920x1080. Anyone know what the issue is? I have to play on 900P and lower resolutions or use VSR and use high resolutions like 3200x1800 or 16:10 like 1920x1200 and stretch it to the 16:9 shape

put on scaling by gpu and adapt picture to panel size in your gpu seyying black border should go away .

Thanks for the reply but the issue wasn't quite that simple. There is no black borders when if I use the computer normally. By normally when I'm just on the desktop using other programs, web browsing, watching videos at full screen, you name it and the picture is sized just right at fullscreen 1080P. But everytime I try to play game in fullscreen mode on 1080P or run 3DMark at 1080P full screen there would be black borders around the screen. No combination of settings in Catalyst I tried worked (including what you suggested) and I tried every solution/suggestion in similar threads with similar problems.

I did find a fix though. While browsing the web just a few minutes ago I found a blog post about editing registry keys in this situation adding one.

In (HKEY_LOCAL-MACHINE/SYSTEM/CurrentControlSet/Control/Videos/'randomnumbersletters) there are several folders like 0000,0001,0002... In each folder there should be a REG_DWORD named TVEnableOverscan and DigitalHDTVDefaultUnderscan and their DWORD value should be 0. In each folder I had both files/necessary string but in one folder which was 0000 where it only had TVEnableOverscan. Additionally TVEnableOverscan which should have a value of 0 had a value of 1. When I added DigitalHDTVDefaultUnderscan, changed TVEnableOverscan to 0 and reboot the system, I ran a game and initially there was the borders during the introduction of the game but all of a sudden it went to full screen 1080P without borders. After that all other games/benchmarks no longer have borders.
