Finally resolved the issue.Phew!
I figured this out by trying every possible software setting and physical setting combination over and over till something worked.
I have a Darbee Vision DVP 500S (video enhancer)
3D-Bee (3D converter, that is as good if not better than native 3D movies)
Denon X6400H (11.2 4K receiver)
Epson 5040ube (wireless 4K projector)
Xbox one X and Sony PS4
Now the Darbee absolutely would not pass picture coming out the Denon, so by chance and because of OCD (lets be honest, all of us are when it comes to HT) I connected the Denon to the 3D-Bee then to the Darbee then to the Projector and Whalla!
It worked. Somehow I am under the impression that the 3D-bee strips some metadata and thus allowing the video signal to pass through.
Of course I double checked and went back to the usual Darbee only and no pic.
Now, here's the odd and very perplexing issue (which I can live with) With the 3D-bee and Darbee in line, my Xbox "4K out" in the settings is not available ony 720 or 180P. No biggie, since I connected Monitor 2 out to the Projector #2
input, but I have to turn the 3D-Bee off in order for 4K to show up (with the 3D Bee turned on, 4K its not available on the Xbox video settings, weird right?)
I think I might be one of the very very very few out there with this set up, but if anyone should come across this issue, This is the way to resolve it and have your cake and eat it too
Incase anyone was wondering, here's some info on teh 3D-bee:
