I can fix this again by going to windows settings, and changing the refresh rate to 60hz and then back to 75hz, WITHOUT using CRU again. Therefore I think the CRU settings are being saved, but not applied automatically.

That can only be a driver bug. The driver is what applies the override. Try creating the custom resolution with AMD's Radeon Software using the CVT-RB timing standard.

Unfortunately it does not work using CVT-RB in AMD Adrenaline, since I cannot specify vertical blanking. I guess you can't do anything if it's an AMD driver issue....

Could this be related to me having the same monitor twice in the drop down? I tried to delete it but it does not work.

Hi ToastyX,

I think I figured it out. I use the same monitor with my work computer and personal computer (separate inputs) and the issue might be caused by the monitor switching inputs. I tested this by turning the monitor off and on again, and it results in the same issue with the CRU settings not applied. The computer was on the whole time so it wasn't actually caused by windows going to sleep.

Is this still an AMD driver issue or is there some way to fix it?

Thanks.
