Hiya guys, just put in this new card (gts450), got a hdmi cable, a big tv. The LG 42" says no signal, the computer knows there is a TV plugged in and has all the resolution/sound options etc but there's no image/sound. I've fiddled with every setting, upgraded to the latest drivers and I've hit a dead end. Both the TV and the cable work fine, tested it with a friends laptop and it instantly appeared.
So I assume it's a problem with my computer or the card, probably software but I have no idea what it could be. Is there such thing as a hdmi driver in general?
