I know, I know. Obviously that was being cheeky. It's just that the Darblets have so often been the source (or exacerbation of) HDMI handshake issues.
My weird handshake issues and audio drop outs only disappeared when I got rid of my Darblet in the chain (didn't matter where I placed it in my chain).
I'm far from the only one.

For those that have experienced a lock up, rather than unplugging the projector, try disconnecting the HDMI cable either at the projector or at the AVR/Source and letting it sit about 15-20 seconds. That will restore functionality to the projector without needing to do a hard power down. If 15-20 seconds doesn’t do it, just wait a little longer. The projector will go back to a blue screen when it has cleared the issues that caused it to become unresponsive.

For those that have only changed projectors and still have all the same equipment. If you are having a problem, it does not necessarily automatically mean the problem has to be the projector, because it worked fine before. As soon as you connect a display with 4K capability there is the potential for everything to change. Suddenly the receiver does a “hey, how ya doin” with the projector and realizes it’s 4K. So, now the receiver 4K modes/scaling come alive. 4K is being passed through the cables which may not be adequate. Then you throw other devices into the chain which had been happy, but now may be seeing something different. This is why I keep telling people to check other items in your chain. The vast majority of people are not having problems, so something must be different between their setups and those that are having problems.

The new Darbee will have phaseHD support for HDMI lengths 30+ meters.

I sponsored the indiegogo campaign for a DVP-5100CIE. Those are supposed to be shipping next month...finally.

So hopefully the handshake issue related to Darbee will be resolved soon. smile.gif

Sounds good.

Replacing the Darblet with the Lumagen 2041 VP fixed it for me, and I still get Darbee processing. I also prefer the Darbee processing from the Lumagen vs the Darblet. Apparently testing by Lumagen (and others) showed that the Darbee processing is best applied to the source before further scaling processing, vs at the end of the chain, as you'd get employing the Darblet. I do indeed find the Darbee processing to be finer and more natural
looking via the Lumagen. FWIW.

I will gladly try this next time my projector locks up. Wish I had known about this trick before, though...my lamp certainly took a few hard hits I would have preferred to avoid...oh well, a new lamps costs only a few hundred bucks I guess...mad.gif

Yeah, I'm going to jump on the Lumagen bandwagon after all the hardware is upgraded to the new 4K standards. And Darbee supports 4K. In 5 years times, imagine what wonderful toys we will all have to talk about. biggrin.gif

I agree. I took it out of my chain thinking it was what was causing my pink flashing rez change issues but alas it was not. Putting it back in I once again realized it's obvious benefit (which looks great when you dial it in sparingly with the other 57 settings).

Rich - When you took out the Darbee, you also removed an HDMI cable as well so it wasn't the only thing which changed in your chain (not to mention a new length seen by all devices in that chain).

+1

I did remove the HDMI FWIW but I guess I didn't wait long enough (only about 10sec). rolleyes.giffrown.gif

"Those" denotes multiple occurrences… multiple occurrences should concern JVC and precipitate action. Any knowledge this is happening Mike or that you've discussed it with them which you care to share (as for most here you are our dealer)? I appreciate what you're saying and agree but in my case there is no scaling going on in my Denon; only the Lumagen and I have a hard time believing it has anything to do with the lock-ups (maybe rez problems, but then I don't have any unless sloooow changes are considered normal these days w/ an $8K PJ; if no... then yes… I'm still having rez problems too). Thx!

i also 2nd this i have the following ... Device(6ft cable) > Gefen Gtb Hdfst 848 (50ft cable) > Denon 4311CI (6ftcable ) Lumagen mini 3D (6ft cable) Darbee DPV-5000 (40ft cable) to X700

no issues here on any of the 3 firmwares, stock,Update1,update2... i've updated them along the line just because... even tho i know its not broken so i shouldn't try to fix it

We watched Captain Phillips tonight (via Apple TV).

Boy did the contrast of this projector shine. Especially the DI. I had it set on -4 for the aperture setting, with the Auto 2 mode, so bright and mixed scenes were super punchy but the darkest scenes still looked
fabulous and inky dark. It's great having the DI do the work for you, optimizing for each type of scene. And I wasn't once aware of any DI artifacts while watching.
