Windows 7: Problem with Nvidia 9800 to philips tv

Problem with Nvidia 9800 to philips tv


Have a 9800gtx n a philips 32in tv and windows 7

Basically there is a known problem with Nvidia cards to Philips TVs.

What happens is when I connect through HDMI the TV flashes up 'no video signal' or 'unsupported video format'.I've been through allsorts like length or quality of cable, changing drivers, resolutions, refresh rates, tinkering with Nvidia control things, nothing.

Looked on here and got a resolution:

GTX280 and HDMI to DVI problems - NVIDIA Forums

HOWEVER, since upgrading drivers to windows 7 version, things have changed and its back.

The problem is the EDID of the TV as a monitor, and in older drivers there was a .inf fix to override it, but in newer drivers for Nvidia the layout on the .inf is different so this fails. I would happily keep the old driver, but it prevents my ability to play blurays which is a big part of my computer (media center).

Old layout of .inf

The fix line is in bold, and the numbers are the EDID code of my tv.

new drivers layout:


Any ideas guys?
What im looking for really is an override same as before but for the new layout .inf because it worked perfect before.
