I recently got a 47" LCD HDTV for my living room, and I have been wanting to plug in my laptop to it. Well i got an HDMI to DVI cable, but when i plugged it in, nothing came up on my screen, after doing all the proper screen setup in Vista. I have fiddled with refresh rates, resolution's, etc. Nothing will work. I have yet to check the settings on my tv itself though.
My laptop see's the TV when it's plugged in, it even recognizes that it's a philips. It's an nVidia GeForce GO 7300 in my laptop, and I can run Bioshock on it even.
