Seeing multiple displays, can't install vista. laptop broken?
When I boot up my HP dv9500 laptop, i get 4 duplicate displays horizontally, ie. 4 displays one on top of each other. on my screen this starts when i boot the computer even on the HP logo. there are black lines inbetween each display almost like if you were playing multiplayer on an Xbox or PS2 system, stead all 4 are one on top of each other non scaled. this happens sometimes, but sometimes i get 1 display but there neon dots all over the screen? The computer lets me install windows but once it restarts after installing Vista, i get a blank blue screen. Can this be a problem with the Video card, HD, Ram, or CPU? is there a way to test all these through the bios? thanks.


Update: I have now installed windows 7 and it works well, but i still "sometimes" get the 4 duplicate screens. When i don't get the duplicate screens i get several lines going vertically that kind of change colors according to wallpaper. I've installed the latest video drivers, yet the computer won't let me set up multiple displays?

Thanks

Have you spoken to HP customer support. It sounds like a hardware failure.
