Hello all.
I've got the same issues as all of you concerning my P2 and the Denon 3700h being completely incompatible.
Contacted Optoma a week ago and haven't even heard back from them yet
Magically got the 2.1/ARC connection to work perfectly about a week ago for an entire film with Atmos but since have only had static/flickering/color issues/etc.-
However, playing xbox games w/ Atmos works through ARC eventually (up to 2 minutes wait)
Q1
-Should zone 2 support 4k video/Atmos? My UHD blu rays are downsized to 1080p 24hz when attempting to use this connection for some reason (through xbox) and even with it I am still getting the handshake issues sporadically.
Q2
-Is the Atlona EDID Emulator for 4K HDR HDMI Signal available anywhere in Europe/France as this appears to be the only viable solution at present?
Comil/FVS (the official resellers here) don't have/carry this item at present and Atlona has been slow to respond here for alternatives.
Have a nice day/night all!
