My monitor is SyncMaster 920NW(1440x900) till yesterday everything was normal, but this issue occurred, I accidenlty pushed the auto adjust button on my monitor and now it's cut off on the top, I tried to push it again, reinstalled graphic drivers and monitor's but it isn't helping. I also tryed to adjust vertical position manually from the monitor, but it moves only a few mm. On the lower resolution everything alligns normally.
