hi! i recently traded my 8800 ultra for a 9800 gx2 and after installing it. My picture was off center and the icons are pixelated. To make my story short the picture SUCKED!
so anyways i called evga tech and they cant help me fix the problem. But one of the techs suggested a FIX posted by one of the members on the forums.

It involves changing the .inf file. I did it and it WORKS!

heres the procedure:

Basically you can use a registry key to override the monitor advertising itself as an HDTV (by setting the number of EDID extensions to 0). Using the following steps, I am now getting proper 1920x1200 resolution on my LG monitor:

1. Start the installation of the latest Nvidia drivers and cancel out once the files are extracted
2. Open nv_disp.inf. By default for the current drivers this is in C:\NVIDIA\WinVista\169.25
3. In the [nv_SoftwareDeviceSettings] section add the following:

*For LG 24" lcd
NOTE
The first 4 bytes (1E,6D,3F,56) in my OverrideEdidFlags0 are specific to the LG monitor I'm using. For other monitors, you will need to replace them. Using Phoenix EDID Designer, extract the current EDID and open up the byte viewer. The bytes are in byte 8 through 11.

4. Uninstall your current drivers and reboot
5. Install the modified drivers by running the previously extracted setup.exe. By default for the current drivers this is in C:\NVIDIA\WinVista\169.25. You'll get a warning about the driver not being signed because of the modified inf. Just press OK.

For Viewsonic VX2835wm it was

I hope this helps other people having HDMI problems.

nice fix man. bump and +rep for you.

That doesn't mean it isn't a EDID issue... it could be the EDID telling all the drivers the wrong specs. I wish TVs followed the EDID rules better like monitors.

I hate to bump this baby but I am afraid I need some help figuring out my four digit number for my 47" Phillips using the Using Phoenix EDID Designer.

Any help is appreciated. Thank you.

Hey, I also need help with the Phoenix EDID Designer.
You say "The bytes are in byte 8 through 11." but I can't figure out what you mean by that. Which ones are the ones I need?
