CompTIA A+ Core 1 (220-1201) — Question 156

A user is having issues displaying the contents of their laptop screen on a projector. The laptop is connected using an HDMI cable, but the screen displays a message indicating there is no signal. Which of the following should the technician do first to diagnose the issue?

Answer options

• A. Check the projector input sources.
• B. Replace the HDMI cable.
• C. Change the resolution of the screen to 1080p.
• D. Verify the HDMI port is not damaged.

Correct answer: A

Explanation

The first step in troubleshooting this issue is to check the projector input sources to ensure that it is set to the correct HDMI input. If the input source is not set correctly, the projector will not display the laptop's output, leading to a 'no signal' message. The other options may be necessary if the input source is correct, but they are not the first thing to verify.
