It seems like you're encountering a resolution issue where your display is stuck at 800x600 despite the settings indicating it should be 1900x1200. Since you mentioned that you are an I.T. professional and suspect it's not a driver problem, there might be other factors causing this. Here are some troubleshooting steps you can take to try and resolve the issue: 1. Check Display Settings: - Verify the display settings in Windows again to ensure that the correct resolution (1900x1200) is selected. - Ensure that the refresh rate is also set correctly (commonly 60Hz). 2. Graphics Card Settings: - Access the NVIDIA Control Panel (since you have an 8500GT) and check the resolution settings there. - Make sure that the NVIDIA Control Panel settings match your desired resolution. Adjust if necessary. 3. Disable GPU Scaling: - In the NVIDIA Control Panel, check if GPU Scaling is enabled. Sometimes, disabling GPU Scaling can help in resolving resolution issues. 4. Check PDF App Settings: - Since you mentioned the issue occurred after opening a PDF file, try closing the PDF application and see if the resolution returns to normal. - Restart the system after closing the application to ensure that any temporary settings it applied are cleared. 5. Update PDF Software: - If the issue persists, consider updating or reinstalling the PDF application you used. Sometimes, certain applications can affect display settings. 6. Monitor Connection: - Verify the connection between your monitor and the graphics card. Ensure that the cable is securely connected. 7. System Restore: - If all else fails, you might consider performing a system restore to a point before the issue occurred. This can help revert any recent changes that might have caused the problem. Since you mentioned that you have the newest driver installed for your 8500GT, focusing on settings adjustments and potential conflicting software might help in resolving the resolution problem. If none of these steps work, feel free to provide more details for further assistance.
