Either the monitor is messed up or the or the video card or drivers are.
If it's the monitor, try another monitor.
If it's the drivers, boot to safe mode and uninstall what you have, then install new drivers.
If it's the video card, try another video card and see if it's fixed.
If it's not those, then I must be your OS install or maybe a bad cable.
