Windows 7 LCD or Video Card?

[nomad]

I've been running windows 7 on my laptop (Dell XPS 1530) for about 6 months and its been working well. Today I used my computer and it was fine, came back a couple hours and turned it on and nothing is appearing on the screen

The backlight is working and i can tell the screen is turning on, just no image. Plugged it into an external monitor and it works. BUT it will only allow me to display in 800x600. Under display it says Generic non-php Monitor on Standard VGA Graphics Adapter."

At first i thought it was the LCD thats busted, but this makes me think its possibly the video card..any suggestions?

If it is the video card is there any way to improve the resolution on the external for the time being?

Many thanks

It sounds like you are experiencing a display issue with your Dell XPS 1530 laptop running Windows 7. Based on the symptoms you described, here are some possible solutions and suggestions:

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.

       Additional Recommendations:​

       • Backup Data: It's always a good idea to back up your important data in case any hardware components need to be replaced.
       • Professional Help: If you are unsure about performing these steps yourself, it might be best to consult with a professional technician who can diagnose and fix the issue accurately.
       Let's start by checking the drivers and see if updating them resolves the issue. Would you like assistance in finding and updating the drivers for your video card?
