Question 13

Today when Dylan turned on his computer, he noticed that the monitor was very dim. He could still see the desktop icon and text. He turned the brightness all the way up, but that did not correct the issue. Dylan also checked to make sure the Power Options brightness was not turned down, causing the screen to go dim.

What caused the screen to be very dim?
A) Input connector on the monitor is faulty.
B) Monitor's power connector.
C) Monitor backlighting.
D) Monitor has Power Save mode enabled.

Accepted Answer

The issue described is indicative of a problem with the monitor's backlighting.

The fact that connecting a different monitor resolved the issue further supports that the problem lies with the original monitor's backlighting, not with the computer or its settings.
