Resolution Fail cant play

ok same has been noted for all i can do graphicly.

when i load intop a game or match up my screen starts in just past the middle of my wide screen

my screen is capable of 1680 x 1050 and 1280 x 768.
the game will not load 1280 x 800 giving an error message
800x600 starts at the center of my screen and goes to the one side 1024 x 768 does the same thing even when i bring my resolution down to 1024 by 768 the in match screen starts at the center.

however the menu screens are fine i can get all the way to a match with perfect graphic

P.S. i ran a search and came up empty handed
