I am having a strange issue with my new monitor that I just purchased. It is a Samsung SyncMaster 215TW. I see these horizontal lines moving down the screen (at least that is what it looks like). It does not take place everywhere, just in certain spots...it seems like it is only occurring on the far left side, the far right side, and the center. I thought maybe it was the power outlet, so I hooked it up to a UPS and plugged it into a different outlet, still nothing changed. Then I hooked up a different computer and it still did the same thing. So now I have ruled it down to the monitor as the problem, so I am wondering if it is a simple setting that needs to be changed (even though I have the recommended resolution and refresh rate set), or is it just a bad monitor that I need to send back? What could possibly cause this kind of behavior from the monitor.
