Windows 7 windows 7 driver geforce 8500gt TV resolution problem

[coobullets]

I am running windows 7 32 bit version. I am using geforce 8500gt to connect my monitor and TV. I have extend the desktop through HDMI cable to my 52" sony LCD TV. I have set the resolution for my TV to 1920 x 1080 which should be fully supported by my TV. For some reason, the TV doesnt allow me to change the aspect of screen and the picture mode because it doesnt recognize the PC HDMI input with resolution of 1920 x 1080. However resolution setting still indicate the TV has 1920 x 1080. I have tried loading the latest nvidia driver from nvidia's website directly or let windows 7 automatically search for the driver to install. Either way after the driver is installed and rebooted, my TV will recognized the input as 1920 x 1080 right away and I am able to change the aspect and picture mode. However after maybe half hour, the problem will occur again and doesnt allow me to make aspect and picture mode adjustment. This is very weird as it has never happen before when I was running vista.

It seems like you are facing an issue with your setup where your TV intermittently fails to recognize the PC HDMI input with a resolution of 1920 x 1080 when connected to your GeForce 8500GT graphics card. Here are some troubleshooting steps you can try to resolve this issue:

Troubleshooting Steps:​

1. Check HDMI Cable and Connections:
   • Ensure that the HDMI cable is securely connected to both the TV and the graphics card.
   • Try using a different HDMI cable to rule out any cable-related issues.
   []Update Graphics Drivers:
   • Reinstall the latest NVIDIA drivers for your GeForce 8500GT graphics card.
   • Completely uninstall the existing drivers before installing the new ones to ensure a clean installation.
   • You can use Display Driver Uninstaller (DDU) to thoroughly remove the current drivers before installing the new ones.
   []Power Cycling:
   • Try power cycling your TV and the PC. Turn off both devices, unplug them from power, wait for a few minutes, and then plug them back in and power them on.
   []Reset TV Settings:
   • Reset the TV settings to default and reconfigure the display settings.
   []Check for Overheating:
   • Ensure that your graphics card is not overheating. Check the temperature of the GPU using monitoring tools like MSI Afterburner or GPU-Z.
   []Check for Windows Updates:
   • Make sure your Windows 7 installation is up to date with all the latest updates.
   []Test with Different Resolutions:
   • Try setting the display resolution to a different setting to see if the issue persists at other resolutions.
   []Monitor TV Settings:
   • Check for any specific settings on your TV related to HDMI inputs and PC mode. Some TVs have specific settings for PC input.
   []Check HDMI Port:
   • Try connecting to a different HDMI port on your TV to see if the issue is related to a specific port.
2. Check for Interference:
   • Ensure there are no sources of interference near the HDMI cable that could disrupt the signal.

     Additional Suggestions:​

     • If the issue persists, consider testing the setup with a different graphics card or on a different TV to isolate the problem.
     • You can also try adjusting the refresh rate in the display settings to see if that helps stabilize the connection.
     If none of these steps resolve the issue, please provide more details about your system configuration, including any recent changes or updates that might have occurred before this problem started happening.
