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

A user is working on a Windows laptop in a conference room that has connectivity to a large-screen TV. The user attempts to connect to the TV using HDMI and
VGA cables, but video does not display on the TV. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The TV resolution does not match the laptop
• B. Screen mirroring is disabled
• C. The screen brightness is set too low
• D. There is a bad composite cable

Correct answer: B

Explanation

The correct answer is B because if screen mirroring is turned off, the laptop will not display its screen on the TV, regardless of the connection type. Option A is incorrect as resolution mismatches typically still allow for some display output. Option C is not relevant to HDMI or VGA connections affecting video output. Option D is also wrong because it refers to a composite cable, which is not being used in this scenario.
