On the bottom of my monitor there is a black sometimes pixelized bar that runs horizontal how to I fix this?

It's only about an inch wide but runs all the way across horizontally. It changes color sometimes and the connections are good. When I shut my computer down the monitor stays on for a moment and then goes off but for the moment while its on the bar is still there. This is a new Gateway computer with Vista and a HP vp15 monitor. Whats the deal!|||Sounds like a monitor or video adapter problem.





If you have another monitor, try connecting that and see if the problem goes away. If it does, the first monitor is failing; if it doesn't, the video adapter is failing.





If you don't have another monitor, try checking that all cables are connected securely. If the problem persists, it's a problem with the monitor hardware or the video adapter hardware.





If this is a LCD monitor, make sure that the screen resolution you've set in Windows matches the native resolution of the monitor.





If the connections between PC and monitor allow for both digital and analog, try switching between them to see if the problem goes away.
