I'm using Catalyst Control Center 13.9 (version 2013.0830.1944.33589) with my Powercolor Radeon HD 7850. I activated "Enable GPU scaling" inside "My Digital Flat-Panels" -> "Properties".
Now I want to deactivate it, because games (like GTA IV) seems to be more blurry with activated GPU-scaling, even if I run the games with the lowest possible graphic-settings.
If I untick "Enable GPU scaling" and click on "Apply" the checkbox is still ticked, even if I reboot or fully reinstall all AMD-stuff installed on my PC.
How can I deactivate the GPU scaling without using CCC? Or how can I get back to "normal" mode
