I'm not saying that it's your program's fault, I suspect Windows (using 8.1 now) and/or AMD Catalyst (14.12 Omega at the moment) have a lot to do with it failing, but I was unable to resolve the issues that I had over the past few months.

What I wanted to do was fairly simple: I wanted to bump my LCD from 1080p@60Hz to 75Hz, and also set my CRT to a custom resolution of 920x690@170Hz. Obviously both of the monitors are capable of achieving this.

LCD: I couldn't get 75Hz to work automatically, I had to manually set it 70-90% of the time after every reboot. Sometimes it did work properly, but I don't know why.

CRT: After every reboot the resolution automatically changed to 1024x768@140Hz. Bare in mind that this is with all other resolutions being deleted from the EDID. I could, however, get a consistent result using 800x600, but only at a refresh rate of 160Hz. I had to set 170Hz manually every time.

I did try manually editing the Windows registry to change the default resolution and refresh rate, but the keys were being overwritten after every reboot, even when I removed all SYSTEM permissions.

AMD's driver has a bug with Windows 8.1 where EDID overrides don't always load properly after rebooting. Restarting the driver with restart.exe will load the override properly, which shows the problem is with the driver and not the override.

I don't know why this only affects some people and not others. Do you happen to have Samsung Magician installed? If so, does removing that make any difference?
