CompTIA A+ (220-901) — Question 17

A user is reporting that a desktop monitor backlighting is very dim. Which of the following should be performed FIRST when troubleshooting the problem?

Answer options

• A. Update drivers
• B. Reseat the video card
• C. Use OSD tools
• D. Replace the monitor

Correct answer: C

Explanation

The correct answer is C, as using the On-Screen Display (OSD) tools allows you to quickly check and adjust the brightness settings of the monitor, which is often the cause of dim backlighting. The other options, such as updating drivers or reseating hardware components, are more complex and may not directly address simple brightness adjustments.
