You work for a small city IT department, and you are investigating a complaint from a laptop user that the image on her LCD display renders only multicolored vertical lines, but the image is fine when the laptop is connected to an external monitor. What could be the problem?

A. The LCD display is damaged.

B. The LCD video cable is damaged.

C. The on-board video adapter is damaged.

D. The laptop is set to only use an external monitor.

Solution

Please find the answer below:

A. The LCD display is damaged.

Beacuse the image rendering problem is only while he renders in his LCD display, and the same image renders properly when it is connected to any external display, which means the on-board video adapter is not damaged, also the video cable is not damaged. Also it renders properly when externally connected, it means laptop is meant to use external monitor also. Thus the problem is only with the laptop\'s LCD display.
