CompTIA A+ Core 1 (220-1001) — Question 342

A vendor connects a laptop to the projector for a presentation but notices the projector is not listed as a display in the display properties. Which of the following troubleshooting steps should be done FIRST?

Answer options

• A. Ensure the projector is on.
• B. Install the projector drivers.
• C. Update the graphics drivers.
• D. Verify laptop compatibility.

Correct answer: A

Explanation

The first step in troubleshooting this issue is to confirm that the projector is powered on, as it must be operational to be recognized by the laptop. If the projector is off, it won't show up in the display properties, making any further troubleshooting steps unnecessary. The other options, such as installing drivers or updating graphics, are only relevant if the projector is on and still not detected.
