Today I installed new motherboard, RAM, cpu and Graphich card. Graphich card is: R9 280x. My monitor is syncmasetr 2343, native res: 2048x1152 and it's got only VGA connector so I had to use DVI to VGA adapter to connect GPU to Monitor. When I turned up pc I installed AMD drivers and when I wanted to change resolution max was 1600x1200 and Generic non PnP monitor. I changed resolution with AMD Catalyst Control Centar to 2048x1152 but screen is so much shaking and there are black bars on every side. I can set res to 1920x1080 in AMD Catalyst Control Center but it looks blurry because that's not my monitor native resolution.

Any idea what's causing problem and how can I fix this?
