I am using the EDID override driver to set the screen refresh rate. I am trying to set my DELL 2209WA to 75Hz in 1680×1050. This works but it goes back to default 60Hz when waking up from sleep mode. I assume this has something to do with the ATI graphics card. How can I configure it to stay in 75Hz mode?
Specs:
- Dell 2209WA
- ATI Radeon HD 4550
- Win 7 64-bit
Uninstalling ATI Catalyst Control Center solved my problem.
