Possible Causes:​

1. LCD Panel Issue: The absence of any image on the laptop screen while the backlight is working could indicate a problem with the LCD panel.
2. Video Card Problem: The output issue when using an external monitor could point towards a problem with the video card or its drivers.

   Suggestions and Steps to Take:​

3. Video Card Troubleshooting:
   • Update Graphics Drivers: Start by updating the graphics drivers for your video card. This can often solve display issues.
   • Check Device Manager: Verify in the Device Manager if the video card is recognized correctly and check if there are any warnings or errors related to the graphics adapter.
   []Resolution Settings:
   • Adjust Resolution in Windows:
     • Right-click on the desktop and select "Screen resolution" (or "Display settings" depending on your version of Windows).
     • Adjust the resolution to a higher value if possible. If the desired resolution is not available, update the graphics drivers as mentioned earlier.
   []External Monitor Issues:
   • Driver Installation: Download and install the correct drivers for the external monitor. This can sometimes enable higher resolution options.
   []Temporary Fixes:
   • Custom Resolution Utility: Consider using a tool like "Custom Resolution Utility" (CRU) to create custom resolutions for your external monitor. This tool may help you achieve a higher resolution temporarily.
   []Hardware Inspection:
   • Physical Check:
     • If the issue persists, it's recommended to have a technician inspect the video card and the laptop's display components to determine the exact cause of the problem.
