I'm having some issues with HDR/HDMI2 with the projector. Other equipment:
Yamaha Aventage 1060
Sony PS4 Pro
Prior to getting the UHD51a the Yamaha, Shield and PS4 Pro all worked successfully with HDR with a Samsung 8000 series LED.
I've been building out a theater room and so far had the projector hooked up to the Yamaha and the nVidia Shield running through the receiver. In this setup everything works fine, I was able to play 4k HDR via Plex as well as streaming content. Effectively no issues and a beautiful picture albeit some occasional 'studder' which may just be playing with PureMotion, streaming quality etc
I then just picked up an x800 as I know true UHD BluRays will look even better. Connected it in through the receiver- nothing. Put in Deadpool UHD, got some sound, but still no picture. I swapped some of the cables I had connected x800 to receiver (all Amazon Basics High Speed) and still no change. I then went into the Projector Settings and changed HDMI from 2.0 to 1.4. Voila, I have a picture...except of course no HDR etc is going through it.
To troubleshoot some more I disconnected the x800 from the receiver and connected it directly to the projector. Now I could get the movie itself to play as HDMI 2/HDR and looked beautiful, but when I tried to go back to the 'home' screen of the x800- nothing. I played a little more with the settings on the projector and was adjusting the HDMI 1 EQ setting and found that around 8-13 I could get the picture to come through at the home screen, but with some flickering. I have no clue what this setting is supposed to do or why it was working.
Having found the EQ setting I plugged the x800 back into the receiver and tried again, no fiddling with the EQ setting- no luck at all.
Since the x800 was new I tried the PS4 Pro to see if it was something with the x800. I connected it through the receiver and no dice. Would not work in HDMI 2 mode at all.
Any idea what could be going on here? If no HDR was working I'd immediately look at the cable, but I don't understand why HDR is working fine via the Shield, but not with any other sources?
My next test later tonight when I get home will be to try and move the receiver closer to the projector and test that connection with a shorter cable (current one is a longer run through the ceiling).
What else might be going on and can I test? Any 'guaranteed' cables at longer lengths that people know work well? (this one is supposed to be rated for 18gbps and 4k x 2k)
What is the EQ setting on the projector and why did it make any difference?
