Run a screen diagnostic (hold D through powerup). If the fault shows on the test screens, it's a bad display panel.
If not, it's more likely a GPU problem -- could be a driver issue but is more likely a dying GPU. Try booting in Safe Mode (see below). If that clears it up, it's a driver issue. If not, it's a failing GPU.
