CompTIA A+ Core 1 (220-1201) — Question 75

A technician sets up a conference room projector that begins to intermittently flicker. The projector is connected to a laptop via an HDMI cable. When the technician connects the laptop to a monitor using the same cable, the issue persists. Which of the following steps should the technician take to troubleshoot the display issue?

Answer options

• A. Adjust the resolution settings on the laptop.
• B. Swap the HDMI cable with a new one.
• C. Replace the projector.
• D. Check and configure the refresh rate settings.

Correct answer: B

Explanation

The correct step is to swap the HDMI cable with a new one because a faulty cable can cause display issues like flickering. Adjusting resolution or refresh rate settings may not resolve a hardware problem, and replacing the projector is unnecessary if the issue could be related to the cable.
