Hey guys. I have searched this issue for the past 4 days and cannot solve it. At some point in the recent past, my 1080p tv, which is hooked up to my computer, has stopped being able to display 1080p at 60hz, but instead only gives me a 59hz or 59.94jz option that is not smooth, but looks stuttery. In the recent past, I had tweaked the monitor settings using apps like CRU, and AmdDownsamplingGUI to achieve better graphics while gaming. Also, catalyst and the windows resolution settings report the display correctly as 1080p/60hz, but in game, it only lists 59 or 59.94 as an option for 1080p. Here are the details
My rig: asus m5a99x rev 2.0 motherboard, amd 8350 processor, with a 7970/280x in crossfire running windows 8.1 64-bit (the problem also existed during windows 7).
What I have tried to fix, or pinpoint the source of the issue:
1. Reinstalled catalysis drivers (even uninstalled using various uninstall utilities for amd drivers).
2. Connected second pc to tv to rule out an issue with the TV. My other oc has a 6870 card and it gave me the 1080p 60hz option correctly.
3. Installed the exact same catalyst drivers the 6870 was using to rule out the drivers.
4. Installed latest beta drivers.
5. Switched the order of the top and bottom gpu and reinstalled to rule out crossfire issue.
6. Removed GPUs and installed each one separately to rule out the individual GPUs being the issue.
7. Upgraded to windows 8.1 from windows 7 to rule out OS issue.
8. Double clicked "reset all" on the CRU folder to restore CRU settings in case that was the cause.
9. Tried different cables and ports (hdmi, dvi, vga)
10. Surprisingly, VGA gives me the 1080p 60hz option in games, but VGA is nowhere near as sharp as hdmi or divi, and I wouldn't consider that a solution at all as there would still be an underlying issue.
11. Updated the firmware on mt tv (Sony bravia).
12. Reset my tv.
13. Updated the bios on my mobo
It isn't my tv since my other pc works just fine in 1080p 60z. It isn't the drivers for my gpu. It isn't the video cards since I tried each gpu separately and in either case I couldn't get 1080p 60hz. What else could it be. It seems that I've eliminated everything from being the cause. The only thing I can think of is CRU and/or amddownsamplinggui having changed something somewhere that isn't fixed my merely reinstalling catalysis drivers! or by simply upgrading from windows 7 to windows 8.1. Could it be some bios setting, or some windows registry that was edited by these programs that I need to unedit? Does upgrading from windows 7 to 8.1 count as a clean install, or does it leave registry files as is from the previous windows 7 installation. If upgrading does perform a clean install, then what else could be causing this?
