Hi everyone....
Having exactly the same problem as mentioned above.
Driving me mental~!
Config:
Ati Radeon 9800Pro 256MB [Sapphire]
monitor: Iiyama Vision Master 502 21" [S102GT]
all resolutions are ok,
exept for 1600x1200 >>
screen shows only 3/4 of desktop;
it moves when cursor is at border of screen.
Tried switching from 85hz to 60hz,
but that makes no difference
anyone who knows how to fix this?
