I just purchased a new Samsung SyncMaster 2333SW monitor. It has a max resolution of 1920 x 1080. I have an ATI Mobility Radeon X1600 display adapter. When I set the screen resolution to 1920 x 1080, the desktop extends beyond the screen right and left. For example, the Start button on the left is completely off the screen.
I installed a second Samsung monitor on another machine and it works fine at the 1920 x 1080 resolution, so I assume that I have some conflict between the monitor and my graphics card. I've gone through the monitor adjustments and the adapter settings, but haven't been able to fix the problem.
