problem
Hi,
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).

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.
Cheers
