CompTIA A+ Core 1 (220-1001) — Question 92

A projector's image begins to flicker during a presentation. The laptop display does not produce this issue.
When a technician changes the resolution on the laptop, the issue persists. Which of the following is the NEXT step the technician should take?

Answer options

• A. Check the connectivity of the VGA cable.
• B. Check the connectivity of the power cable.
• C. Change the aspect ratio on the laptop.
• D. Change the settings of the projector.

Correct answer: A

Explanation

The correct answer is A because checking the connectivity of the VGA cable is essential as a loose or damaged connection can cause image flickering. The other options focus on the power cable, aspect ratio, or projector settings, which are less likely to be the cause of the flickering since the laptop display is functioning correctly.
