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.

I haven't heard of EDID overrides not being applied after turning a monitor off and back on, nor should switching refresh rates cause an EDID override to load. Normally EDID overrides take effect when the driver loads or after a monitor is connected, and in rare cases where it doesn't, the driver has to be restarted. Maybe the settings are actually being applied, but there's another issue causing the memory clock to stay at maximum. You could verify this by adding a refresh rate that doesn't exist by default. If the settings aren't taking effect, the refresh rate won't exist. The second monitor entry in CRU is a side effect of restarting the driver and shouldn't have any effect.

As for Adrenalin custom resolutions, CVT-RB should provide enough blanking already, or you can specify the parameters manually. The total includes the blanking.
