I switched on my computer yesterday to find that my screen had 2 black borders above and below which was odd, so I tried auto-adjusting my monitor, which didnt solve the problem it stayed the same, I went into the Nvidia CP to reposition the screen and I could only move to replace the border on the bottom of the screen, the top was permanent, any way I solved this problem by adding custom resolutions on both the NCP and Vista properties only to fire up PES 2010, and find it was in 1600x1024, I looked in the PES 2010 settings to find that my native resolution (1680x1050) was not in the list, I also tried COD MW2 and Half Life 2 Ep2 and they also cannot display this resolution, only resolutions that a usual 16:9 monitor can.
1680x1050 is my native resolution and i have been using it for 2 years on 4 different computers including this one so what could the problem be?
It would be great if I could find the problem and not have to resort to manually changing the resolution on all my games in future.
I reinstalled the card manufacturer drivers and it still had the same problem, everything is at the right resolution but the moment I start up a game it cannot go onto the native resolution.
Any help would be appreciated thanks anyone
