CompTIA A+ Core 1 (220-1001) — Question 271

A user reports that a small part of a laptop's screen displays black instead of the appropriate color. A technician changes the display settings on the user's laptop and then runs onboard diagnostics; however, the issue is still not resolved. Which of the following should the technician perform NEXT?

Answer options

• A. Update the video driver.
• B. Replace the digitizer.
• C. Test for dead pixels.
• D. Check for recent updates.

Correct answer: C

Explanation

Testing for dead pixels is the next logical step as it directly addresses the issue of a part of the screen displaying incorrectly. Updating the video driver may not resolve a physical screen problem, replacing the digitizer is unnecessary at this point, and checking for recent updates does not relate to the specific screen issue.
