CompTIA A+ Core 1 (220-1001) — Question 272

A manager is trying to display a presentation using a ceiling-mounted projector in a conference room. The projector displays a "no signal" error on the pull-down projector screen. A technician verifies the projector's input cable is securely connected to the manager's laptop, and the laptop is set to presentation mode. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The laptop does not have the proper display driver installed.
• B. The Miracast settings are improperly configured.
• C. The projector is not compatible with the manager's laptop.
• D. The source type is set incorrectly on the projector.

Correct answer: D

Explanation

The correct answer is D because if the source type on the projector is not set to match the input from the laptop, it will display a 'no signal' error despite the cable connection being correct. Option A is incorrect as a missing display driver would typically prevent any output, not just signal issues. Option B is also irrelevant here as Miracast settings would not affect a direct cable connection. Option C is wrong because compatibility issues would generally result in the projector not functioning at all.
