I have a samsung 26 inch HD LCD hooked up to my powerbook. The LCD has a res of 1360x768. When I connect it though the left side has about 150px of black bars and the other side is cut off. So there is a big gap where I would drag something from one screen to the other. If i set it 1024-768 it stretches to fit the whole screen correctly, but in 1360x768 it is bumped over bout 150px. Any ideas?
