I have scaling problems with Radeon HD6850 (HDMI) and Acer S222HQL (HDMI).
Before I switch to HDMI I had used DVI with a "crystal clear" image. Today I switch to HDMI and get a washy look. First the image filled only 90% of the screen then I found the "Underscan/Overscan" option within the Catalyst Control Center and have now 100% fully filled. BUT I get this washy look. A few lines are sharp and many are washy and some realy unsharp.
To get the 100% image I had moved the "Underscan/Overscan" option right to overscan.
I am no realy familar with graphic card settings. I thought that HDMI can communicate as well as DVI. So what is the problem with it? A very bad autoconfig happend...
