I have a client with a fairly basic Mac Pro setup. He has the standard ATI 2600 graphics card connected to two 26 inch Samsung LCDs. The main monitor is ok, but the secondary monitor has about one inch of the far right side that does not work. The desktop area itself is squished in, and not chopped off. So far we have replaced the monitor with another, he has about a dozen at his disposal, we have replaced the VGA cable, and we have switched ports on the video card and re arranged the screen locations in system preferences. No matter what configuration we use, the screen on the right has it's image squished and makes many things look distorted. Just curious if anyone else has had this issue, and what they've done to resolve it. We've contacted Apple care and they originally blamed the monitor, which is why we replaced the screen completely. At some point in the next couple weeks we may have a chance to bring the system to the Apple store, but then we'd need two monitors to demonstrate the problem.
