Im using a Gtx 560 graphics card and a 23" screen (HANNS.G HL231dbp) on windows 7. For some reason windows 7 is only letting me use 1620 x 1200 as my resolution despite the fact that this screen supports 1920 x 1080 as its max. I managed to fix it on my desktop with a nvdia program but the problem is still there for games. If any one knows how to get pass this or fix it please tell me. I am also using a VGA cable for the screen if that would effect it in any way.
