CompTIA A+ Core 1 (220-1101) — Question 351

A user added a heater underneath a desk, and now an external monitor is not working. A technician verified the monitor gets power. Which of the following should the technician do next?

Answer options

• A. Have the user unplug the heater.
• B. Replace the monitor.
• C. Open the display settings on the computer.
• D. Ensure a VGA cable is connected properly.

Correct answer: D

Explanation

The correct action is to ensure the VGA cable is connected properly, as loose connections can lead to display issues. Unplugging the heater may not resolve the monitor problem, replacing the monitor is unnecessary if it receives power, and checking display settings is not the immediate next step since the primary concern is the connection.
