CompTIA A+ Core 1 (220-1101) — Question 183

A user calls the help desk about a 4K monitor that will not output an image from a desktop. The monitor was working previously but now shows a black screen with a message stating a signal is not detected. The desktop is connected via HDMI, and the monitor has an empty DVI port. Which of the following steps should the technician perform FIRST? (Choose two.)

Answer options

• A. Check the version of the HDMI cable.
• B. Check the input source.
• C. Set up the desktop for DVI.
• D. Replace the HDMI cable.
• E. Install OS updates.
• F. Initiate a system restore.

Correct answer: B, D

Explanation

The first step should be to check the input source (B) to ensure the monitor is set to the correct input for the HDMI connection. Replacing the HDMI cable (D) is also a logical step if the input source is correct, as a faulty cable could be causing the signal issue. The other options do not address the immediate concern of detecting a signal from the desktop.
