CompTIA A+ Core 1 (220-1101) — Question 27

A technician is setting up a projector for a videoconferencing system. When the user attempts to connect a laptop to the system, the system displays the following error message: no source found
The user tries multiple cables and inputs on the projector. Which of the following should the user try NEXT?

Answer options

• A. Check the bulb on the projector and replace it with a new one.
• B. Check the display settings on the computer and set them to extend/duplicate.
• C. Replace the projector with another known-good one and try again.
• D. Replace the video card on the machine that is plugged in to the projector, as it has gone bad.

Correct answer: B

Explanation

The correct answer is B because checking and adjusting the display settings on the computer can resolve connectivity issues. Options A and D are less likely to be the cause of the issue, as the projector appears to be functioning but not receiving input. Option C is also not the best next step, as the problem likely lies with the laptop's settings rather than the projector itself.
