I have a RGBHV cable I got from AVcable that is BNC to BNC. Is there no BNC ouput? All I see is DVI out. Why can't I begin to setup a resolution on my pj when it says progressive in and 720p RGB out? my dvd is hooked up correctly. My RGBHV cable is into my NEC 6PG Plus (6100) pj and i'm trying to add a new signal. Please help.
