Show answer and explanation
Correct answers: A, C
Explanation
When an external monitor is not displaying content, the first step is to verify display settings to ensure the monitor is enabled and properly configured (e.g., as an extended or duplicated display). Additionally, using keyboard shortcuts like Windows + P can help quickly toggle between different display modes to allow the external monitor to function correctly. Other options, such as adjusting brightness or reinstalling drivers, are less likely to address the issue directly in this case.
- A. Correct.
Checking the display settings is essential to ensure the external monitor is enabled, as it may be turned off or set as a secondary display without active content.
- B. Incorrect.
While brightness adjustments may help with visibility, it would not resolve the issue of the external monitor not displaying any content. This is unlikely to be the root cause in this scenario.
- C. Correct.
Using the keyboard shortcut to toggle display modes (e.g., Windows + P for 'Extend' or 'Duplicate') can help establish the correct display setting for the external monitor.
- D. Incorrect.
Uninstalling and reinstalling graphics drivers should only be done as a last resort after verifying basic settings. It is not necessary in this scenario.
- E. Incorrect.
Restarting the laptop could help in some cases, but it is not the most efficient or direct way to resolve this specific issue.
