Good idea, but isn't the cable working as expected if the PJ displays a picture when hooked directly to the source (Oppo BDP-103) vs through the AVR X-4000?
It would appear the issue is that the Denon is not putting out a strong enough signal for the cable to work, whereas the Oppo is.
Or, should the cable just work regardless of source (Oppo vs. Denon AVR?)
I picked up a $20 HDMI extender from RS last night (didn't want to wait for MonoPrice to deliver one)..will try that tonight to see if it helps. Am also thinking HDBASE-T or two shorter HDMI cables with a HDMI extender between them as a workaround.
Fortunately, the Oppo has HDMI IN and split A/V between two HDMI ports. So, I can run the PJ directly to the Oppo (Redmere cable works) and the 2nd HDMI cable into the Denon X-4000. Then feed a second set of devices via a HDMI switch into the Oppo. That's not a "great" solution, though, since switching input sources on the Oppo requires navigating up and down a list of possible sources - far as I know, you can't push "INPUT 1" for input 1, etc. So, WAF through the Harmony remote is likely to be pretty low with that approach, and I'd really prefer the $1,200 Denon AVR to just work as it's supposed to - ie: throw a picture consistently via the HDMI out, just like the Oppo does.
It's pretty unacceptable that a $1,200 AVR can't interface to a PJ through HDMI out using the exact same cable that works on a $200 Tivo HD or a $500 Oppo DVD player. That would imply the HDMI port on the AVR is underpowered or has other quirkiness that the lesser cost devices don't, which is crazy.
