RE: Custom Resolution Utility (CRU)

Inspired by the communication, I tried to find a workaround to smoothly one-click switch between all the resolutions, and it seems I figured out a viable solution. I put the resolution with highest refresh rate as 1st in the detailed resolution list (the recommended one), and the rest below in descending order (sorted by refresh rates), as well as some more in custom extension block. With this kind of setup the switching went all fine and automatically chose the defined in CRU refresh rates for each new resolution, except for switching from 2560*1920@60 to 1024*768 or 800*600. The latter two were supposed to function at 160 and 170 Hz respectively, but they one-click switched to 60 Hz. Then I tried to uncheck the 60 Hz boxes for 800*600 and 1024*768 in Established resolutions section of CRU, and after that all worked flawlessly.The behavior you're asking about is specific to AMD's resolution switcher and not an EDID issue. It seems to want to keep the same refresh rate when switching resolutions if possible. From what you're telling me, the driver is also adding the native resolution's refresh rate to lower resolutions as scaled resolutions for some reason. Putting the resolution with the highest refresh rate as the first detailed resolution should resolve this. The order of the other resolutions shouldn't matter. |
