The display you used, was it from the same model laptop?

Could be an issue on the motherboard since you changed the screen, or with the video chip. Does this system have multiple video cards?
thanks for your reply
yes..same model.
no..i see in bios using ati gpu..not multiple (via external monitor)
if gpu problem..should be cannot use external monitor , right?
