Question

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. He connected a different monitor, and the screen was fine. What caused the screen to be very dim?
a. Monitor’s power connector.
b. Monitor backlighting.
c. Input connector on the monitor is faulty.
d. Monitor has Power Save mode enabled.

Answer 1

Answer:

B. Monitor backlighting

Explanation:

The computer system is a machine that can digitally receive input, process the inputted data and display and save results. The computer system is a physical system driven by a software component.

The computer hardware components are classified as input unit or devices, output unit, memory and storage unit, and  processing unit. The screen is an output unit of the computer system, it displays the output or result of the processed data.

The power supply to the screen, in this context, is not faulty due to the other screen used in testing the supply and input connectors. The back light on the screen has failed and that is why the brightness can not be adjusted.
