Strange HDMI connection issue with a 7702 MkII that has worked fine for years. Just bought a JVC X520 projector, with faux-4k capability.
I replaced the through-the-wall HDMI cable with a Monoprice active [email protected]
one that I tested to the new PJ, using the output of an Oppo 203 running 4k signal. I have the correct 'source' and 'TV' ends. I now get no video signal to the projector when running through the Marantz. Nothing, no menus, video or any signal, even at 1080P. Worked fine with the 'old' HDMI cable running 1080P to my 'old' JVC RS46. I've also plugged the HDMI cable from the Xfinity box (at 1080p) directly into the new cable to the PJ, and it works fine.
(Stupidly, maybe, I did not test the cable with the Marantz into the projector......figured if it worked for the Oppo to the PJ using 4k, then the Marantz wouldn't be an issue. Here's the cable: https://www.monoprice.com/product?p_id=13757
The Marantz specs, and the specs of the cable, tell me that there should not be compatibility or bandwidth issues..but obviously something is whacky. If I bypass the Marantz, the Oppo drives 4k signal through the new cable to the PJ, with no issues, and my Xfinity box sends a picture through at 1080P with no issues, so the 7702 Mkii seems to be the problem.
I'm thinking it may be a setting on the Marantz, or something else simple?
