Problem with monitor native resolution

Ok, so i have an LG W2243S-PF 22' full hd monitor. I have a 64-bit W7 installed with 12.10 catalyst (sapphire hd5850) and with the w2243 driver from LG's website. It works fine on 1280x720, but when I try and set it to 1920x1080 (which is the native res), it gets weird and flickery. Here are two pictures:

Have you got any ideas what this might be? Also, I couldn't find a better place to post this... Is there such place? Thanks in advance!

Not sure, but you could try fully uninstalling the video card drivers and rebooting.
Then go to AMD's website and installing their latest drivers.

Also, if the monitor came with any monitor driver, you should also install that too.

The w7 is a fresh install, the monitor driver and the catalyst is installed freshly.

EDIT: I use a DVI-VGA adapter, because the monitor only has a VGA input. Does that matter?

Uninstalling the monitor driver and disabling the edid recognition and setting maximum possible resolution in amd vision engine control center fixed the problem!
