2) Not at all. My comments on HDMI input design were meant to be generic and not in any way specific to JVC. As I mentioned the connection is a system and it might just mean a change that is within spec in the "system" (in this case the JVC input) changes the transmission line reflection points, etc. just enough to cause issues.
For the 18 GHz chips, it may be that the chip's design itself is different due to needing to work with 18 GHz, and this is making it more sensitive to HDMI cable/connector/impedance issues.
Thanks. I understood your suggestion was to move the Lumagen as a test - I just mean that given the way my system is cabled, this is a very daunting task.
But I'm running out of options so I might have to try it.
So the hypothesis here is that the new HDMI input of the new JVC projector is putting different demands on my HDMI cabling, in particular it's ability to communicate with the Lumagen, correct?
(Because the cable already works with the Blu-Ray player only, so it has to be an issue between the Lumagen and Projector).
Just to be sure: I would move the Lumagen 2041 to the projector location, run the long HDMI cable run from the output of my Oppo Blu-Ray player into the appropriate input of the Lumagen, and use a 6 foot cable run from the Lumagen out to the Projector. And if I get a picture working ok, that suggests the problem is the cable and I should upgrade the cable?
In which case, I guess I'd try a monoprice active cable.
What about Cat 6/7 cables? Would those be likely to solve the issue?
(BTW, if I do move the Lumagen and still don't get sync to the projector, what then? Would it still be a cabling issue?)
