I've tried every driver version imaginable, Catalyst 15.7, Crimson 15.12, 16.1 and more. I am trying to set a custom resolution of 1929x1080 @ 120hz on my Radeon Settings. My Sony X850C 4K TV does indeed accept this signal via HDMI and recognizes it. Once I set it, the TV will actually show 1080p 120hz on the top left corner of the screen. People have shown it off running perfectly well via HDMI 1.4 and 2.0 and they did it just by setting a custom resolution in their nvidia or Radeon Settings.
However, I cannot for the life of me set it up. I make the resolution and choose the refresh rate and it fails when it "tests" the resolution. Now Radeon has sooooo many settings that I don't know what to choose for which field. Any help here would be much appreciated
Thank you in advanced!
