Have you tried upgrading your video driver? That would probably be the first thing you want to do. Quick, easy, and free. If that doesn't do it, then you want to find another computer to connect the thing to so you can see if it's the monitor or something with your computer that's at fault. If it works on another computer, then there's something about your computer causing the problem, but if the problem persists to another computer, then it's time to either exercise your warranty rights (if the warranty is still valid) or just get a new monitor.
Hey guys ,
