Windows 7 - Driver for LG 60PG70FR Plasma TV

Hi! I'm trying to connect my Core i7 DH67BLB PC to my LG 60PG70FR plasma tv. While I was installing Windows Ultimate x64 I did it using the HDMI1/DIV option on the TV but the moment I installed the graphic drivers for the motherboard I stoped getting the image on HDMI and can get it only on RGB/PC mode. I have tried chaning the resolution from 800x600 to the highest 2560x1600 to no effect. I also tried to reformat the pc hard drive and reinstall windows but the same thing happened. The HDMI mode only received images till I installed the graphics drivers. And I ahve to install the graphics drivers otherwise the picture is very grainy.

I don't believe that you'll find a driver for the TV--but--check LGs website for a possible firmware update for your TV.
FIRST-- check in your control panels - I believe there are settings that can be altered for the display (it should be part of the Intel driver software that was installed)
