Just wanted to say a big "Thank You! " for the info in this thread.
Have a few Motorola DCX3400 STB boxes.
Hooked one up to a ViewSonic 24" 1080p monitor and it the STB detected 1080i.
Hooked the same one up to a Sony KDL-40EX500 TV and defaulted to 720p (??).
Solution: Pressing the "Format" button on the front of the STB rotates between 1080i, 720p, 480i, 480p. :-)
