ok i delved into the monitor settings. it does indeed seem that the graphic card has many more resolution settings but the monitor is what is holding it back. it seems you need really big monitors to reach the upper resolutions. i think i have a 17 inch monitor. that's a pity. i was looking forward to seeing my program's renders in high resolutions.
