AVR-Key is just released so there will be firmware upgrade for it, so if there is something we can do for your case, we will do it. Need above info first.
Also please confirm that "normal video signal" of 1080p successfully goes thru your HDBT solution or not.
Thanks for trying to help. I did some testing/troubleshooting.
TV - Samsung HU9000 w/ SEK3500u
source - Nvidia shield TV (2017 model)
AVR - onkyo NR737
matrix switch - monoprice Blackbird 4k HDBaseT 4x4 Matrix with PoC, 4K@60Hz
combinations I tested -
shield TV with AVR key - video straight to TV (SEK3500u), audio to AVR via HDBT = video and no sound
shield TV with AVR key - audio straight to TV (SEK3500u), video to AVR via HDBT = black screen and no sound
shield TV with AVR key - video straight to TV (SEK3500u), audio to AVR via 50' hdmi cable = video and sound
shield TV with AVR key - video via HDBT to TV (SEK3500u), audio direct to AVR = no video and no sound
shield TV with AVR key - audio via HDBT to TV (SEK3500u), video direct to AVR = black screen and no sound
shield TV WITHOUT AVR key - direct to TV (SEK3500u) via HDBT = video and sound via TV speakers (AVR out of signal chain)
shield TV WITHOUT AVR key - direct to AVR, HDMI out from AVR to TV (SEK3500u) via HDBT = video and sound. Video up to 4K60Hz 8-bit 4:2:0 is possible.
Observations - the shield TV seems to work perfectly well via HDBT without the avr key. HDBT via my onkyo AVR or straight to the TV doesn't make a difference. Once the AVR key is added to the chain however...
- AVR key CANNOT pass video via HDBT using the monoprice switch... no matter what setting I use (I moved the video switch and got no video no matter what setting)
- AVR key audio out produces a black screen via HDBT and with normal HDMI when connecting as a video source... I think this is what it's supposed to do??
- AVR key can separately pass audio and video just fine once HDBT is taken out of the signal chain and normal HDMI is used.
These are the exact same results I had when using a cheap $35 HDMI 2.0 splitter I bought on amazon. Audio Split with HDBT = no audio. Audio split with normal HDMI cable = audio. Now, not to denigrate the AVR key, but what I think this highlights is that whatever issue that is causing the cheap splitter to be incompatible with my monoprice HDBT switch is the same issue that is causing the AVR Key to not work also.
One "feature" of the monoprice switch is that it has configurable EDID. So that it will effectively limit the source to whatever you set the custom EDID to. It seems that if I just try to let the switch pass the source through without a custom EDID, it just defaults back to a custom EDID. My guess is that the custom EDID is what is screwing things up. The switch has an option of uploading the EDID settings of the source device and allowing to apply that EDID as a custom setting. I pulled the EDID info from the AVR key with the audio only, and applied it to the HDBT switch, but still didn't work.
If you have some sort of ideas I can try, I'm all ears. I ordered a fairly cheap HDBT balun that is a simple transmitter/receiver w/ CAT6 and POE. Has no custom EDID options or anything. It arrives tomorrow. I will test that with the AVR key and see if I get different results. Still... if you could potentially figure out what is causing the issues here and fix it via firmware to work with my 4x4 switch, that would be much preferred. I am fairly certain it should be capable of working somehow... as the shield TV works just fine via HDBT, as does any other device I've connected via HDBT. It's just introducing a splitter that seems to screw things up.
Here's a copy of the matrix manual since it's impossible to find online -
and here's a screenshot of the EDID it pulled from the avr key -
Hope you guys can come up with a solution for me. Would love to keep your device. But obviously if I can't make it work I will need to return it.
