Is the monitor connected to the power? Is the GPU working? Is the monitor working with another device? Is the PC working with another monitor? Is the PC configured to output to the correct HDMI port? Is the monitor input set to HDMI? Are multiple HDMI ports on the monitor used? If so, is the correct port selected? Are there any issues with the PC's display settings in Windows? Are the correct drivers installed on the PC? Is the laptop's external monitor enabled via the Fn key or the appropriate F key? Are the BIOS settings correctly configured?

Diagnosing and Resolving the Issue

To further diagnose the issue, follow these steps:

Start with basic checks: Ensure the PC is on and the monitor is connected to the power. Check that the HDMI cable is not broken and is securely connected at both ends. Check the input settings on the monitor: Make sure the monitor's input is set to HDMI, and if there are multiple HDMI ports, ensure the correct one is selected. Configure display settings in Windows: On a PC running Windows, go to Display settings and ensure the HDMI port you are using is active and selected. Check for correct drivers: Ensure that you have the correct drivers installed on the PC. Outdated or incorrect drivers can cause display issues. Enable external monitors on laptops: If you are using a laptop, make sure the external monitor is enabled via the Fn key or the appropriate F key. Check BIOS settings: If the issue persists, check the BIOS settings to ensure they are configured correctly for the external monitor.

Additional Steps and Tips

If the above steps do not resolve the issue, you may want to:

Swap cables and monitors: Try different cables and monitors to see if the problem persists. This can help you determine if the issue is with the cable, monitor, or PC. Check for software configuration issues: If you recently installed any software or updated drivers, there might be a conflict causing the blank screen. Run Windows troubleshooter: If you are using a Windows PC, you can run the built-in troubleshooter to identify and resolve display issues. Consult the manufacturer's support: If everything else fails, visit the manufacturer's support website for specific troubleshooting steps based on your PC and monitor model.
