I just got my Darbee and am still experimenting with it on my Panny 50GT50, but in the meantime it's awkward shape was making it impossible to integrate into my AV credenza. So i made a little stand for it out of some Monoprice 90 degree HDMI adapters and was able to place it on top my TWC Tuning Adapter below my center channel speaker and it looks ok there.
(2) #3733 90* HDMI adapters
(1) #4859 Flat 90* HDMI adapter
(1) #4860 Flat 90* HDMI adapter (opposite of the #4859)
Tivo S3 > Gefen 2x2 HDMI Splitter/Switcher > Darbee > 50GT50 Plasma (<----This chain caused magenta flash every few seconds so i removed the Gefen)
BTW when i place the Darbee between my Gefen 2x2 HDMI Splitter/Switcher and my 50GT50 i get a magenta flash a few seconds after turning the TV on and the audio also goes away, then the picture returns for a few seconds then i get another flash, and the flashes continue to repeat as long as the TV is on. Cycling the Darbee power and/or the TV's power doesn't stop this behavior so for now i've removed the Gefen Splitter from the loop and everything is syncing up just fine now. I'll fiddle with it more and try moving it around in my chain and try different HDMI cables etc when i get some time but for now i just want to enjoy it
But so far i'm seeing a nice improvement in facial detail etc on 720p OTA and Cable channels which was my only real gripe about the GT50.Edited by RandyWalters - 8/25/12 at 9:54am
