I am using an HDMI to HDMI cable to connect my computer to my TV (Philips widescreen, Model #30PW8402/37). I can get an image on the tv but it is horrible (looks like a bad sallelite signal). I have tried all of the resolution options, but I get the same "snow" for all options. My graphics media manager only has one choice for the refresh rate - 30 Hz, the TV is 60 Hz. Any advice would be greatly appreciated!
