After installing a clean install of Windows 7 professional I can't seem to get the resolution more than 800x600.
I went to the driver section and installed the right Display driver for my NB550D-111: version 8.812.2.2 of the displaydriver.
After a reboot, still nothing happens and I can't change the resolution.
Trying to open Catalyst Control Center results in nothing: i can't seem to open it.
I spent hours and hours trying to fix this issue but need help at this time.
