My TV is a Mitsubishi 55805 (HDTV). The Mitsu only has the Mitsu properietary port (looks like a VGA port but wider and only 2 rows of pins). So... I had to search and search and then search some more. Finally found a VGA to BNC cable at Best Buy back in the computer area. Then had to go to 2 Radio Shacks to get the BNC to RCA adapters. Wish the VGA to BNC was higher quality but it works and the picture is terrific!
