1920 x 1200 is fine, but I play a game which don't support widescreen (ie. Battleield 2142) I'd like to play at 1600x1200 and change the screen to 'aspect mode' to change this. I can't though - this part of the menu is now gray out, so it stays in 'full' (wide mode), even though the display is in 1600x1200. Can I change this? TIA!
