Question 150
A support request at Riverlight Retail presents this problem: A conference room projector displays a no-signal message while the laptop works locally. The supporting record states that the laptop is attached by HDMI but the projector input menu is set to a different port. The desired outcome is to resolve a display source-selection issue without reinstalling graphics drivers. The goal is to restore required function without creating a new security or safety problem. Which planned change most directly resolves the documented issue?
- Select the correct HDMI input and supported duplicate or extend mode
- Replace the suspect cable and secure connectors without unnecessary GPU replacement
- Repair the supported backlight or panel power assembly after confirming external video health
- Back up recoverable data promptly and replace the failing drive
Explanation
Correct Answer
A:
Select the correct HDMI input and supported duplicate or extend mode. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that the laptop is attached by HDMI but the projector input menu is set to a different port. The support goal is to resolve a display source-selection issue without reinstalling graphics drivers; this design action specifically addresses projector wrong input versus computer failure without confusing a different subsystem.
