my monitor is broken right in the middle, its big enough to hide the crosshair.

the crack is big enough to hide the crosshair and a player from long range, now hiding the player isn't an issue because the map and I can just move around but the crosshair doesn't move, is there any other way to move the whole game a bit to the side other than using windowed mode? I dont' like windowed mode because I play on stretch resolution and I dont think that is possible on windowed (unless it is, if so please tell how)
