Caller reports Monitor/Display blacked out; How do you troubleshoot?

Answer 1

To troubleshoot a blacked-out monitor/display, check the power and signal connections, test on another device, adjust brightness and contrast, update graphics drivers, and try a different monitor.

Step-by-step explanation:

To troubleshoot a blacked-out monitor/display, follow these steps:

1. Check the power connection: Ensure that the monitor is properly plugged into a working power outlet and that the power cable is securely connected to the back of the display.
2. Check the signal connection: Verify that the video cable (such as HDMI, VGA, or DisplayPort) is firmly connected to both the monitor and the computer.
3. Test on another device: If possible, connect the monitor to a different computer or use a different monitor on the same computer to identify if the issue lies with the monitor or the computer.
4. Adjust brightness and contrast: Use the monitor's physical buttons or settings menu to adjust the brightness and contrast levels.
5. Update or reinstall graphics drivers: In some cases, outdated or corrupted graphics drivers can cause display issues. Update or reinstall the graphics drivers to ensure compatibility.
6. Try a different monitor: If all other troubleshooting steps fail, connecting a different monitor will help determine if the issue is with the original monitor or another component of the computer system.
