I just hooked up a Sony LCD TV to my PC so I could do dual monitors, but I'm having problems. I contacted Sony, but they were not helpful. I was told to use a DVI to HDMI cable to get the highest quality. I have a DVI out from my PC to the HDMI in on the TV, but I don't get any signal. I know there is a PC(RGB) input on the TV, but I was told I wouldn't get as good of signal using that. Does anyone know what hookup I need to use and how to set up for dual monitors? Hopefully I can use the cable I bought (DVI to HDMI).
