My HDMI screen won`t display 1920x1080p desktop with Radeon HD 7850 2GB

amd radeonamd-catalystgraphics cardhdmiresolution

Specs relevant:

  1. Graphics Card: AMD Sapphire Radeon HD 7850 2GB (should support up to 4096 x 2160)
  2. Screen : BenQ GL2460 (native resolution is 1920 x 1080)
  3. Cable : HDMI cable connected to my graphics card's HDMI slot, and to my screen's HDMI slot.

Well, I know it is unnecessary to point out cable and where it is connected, but now I won't have to answer to that if one would ask me if I did that.

Yesterday I had a TV running with my Radeon HD 7850 2GB on 1360 x 768 @ 60Hz. Today I got my new screen mentioned above, and on catalyst control center (yes, latest version) it says that recommended resolution is 1920 x 1080, so I set it to that. Then my desktop won't use the whole screen. And since my graphics card should be able to support this, I thought it would be something with outdated drivers, so I reinstalled every driver associated with graphics/screen etc.

This did not help. So I found out that the highest possible resolution which uses the whole screen was 1680 x 1050 @ 60Hz which isn't what I paid for.

Since I am not satisfied with working all this summer saving up money for this, I did everything I could do by searching forums and stuff. I saw people having similar problems but nothing which had anything to do with the desktop not filling out the border correctly.

I don't know what else to do. Any suggestions?

Had the same problem and finally solved it. It has to do with overscaling, as @ChrisInEdmonton pointed out in the comments. You have to do the following:

  • Open the Catalyst Control Center
  • Display the My Digital Flat Panels menu.
  • Click on Scaling options (Digital Flat Panel)
  • Turn Scaling to 0%

This will solve your issue.
