The bad:
Included HDMI cable didn’t work
Included remote didn’t work (plugged in another one I had from HTPC which worked fine)
The good:
Reading through the forms and connecting some other dots I was able to make a lot of progress in getting everything playing today. Updated to the latest version after I originally configured it which seems to have removed a couple of the options that have been previously mentioned in other threads such as HDR autoswitching.
Important Note for anyone with a LG B7 or similar: In order to get 4:4:4 support you have to set the input type to “PC” on the HDMI port which is completely not obvious.
Doing this actually fixed two problems I was having: 4:4:4 playback AND 10 bit playback. Once I did this I was able to play 10bit video with 4:2:0, 4:2:2, and 4:4:4 (no more blank screen).
Prior to this I was able to get 8bit playback with 4:2:0 and 4:2:2 but not 10 bit as tested and confirmed by
echo 8bitnow | sudo tee /sys/class/amhdmitx/amhdmitx0/attr AND
echo 10bitnow | sudo tee /sys/class/amhdmitx/amhdmitx0/attr then looking at the conf file while video was running.
So as of now everything seems to work EXCEPT I don’t get HDR (tested w/Sony Swordsmith HDR as well as couple of movies that have it) and am looking for guidance and/or suggestions about where to go from here.
Didn’t test the cable with another device, and I just followed the directions in the manual with respects to the remote (tried switching usb ports, tried multiple times, etc.) I didn’t see any info about repairing and frankly I have a remote with a full keyboard/touchpad that I prefer anyways so no biggie.
Thanks. We don’t know the model of @blkadder’s AVR, only that it’s 4 years old so HDR support seems unlikely.
Edit: It is possible we will be able to force HDR through a non-HDR AVR so don’t rush out and buy a splitter just yet. A quick test on my old Yamaha gets my TV reporting HDR but it’s not passing through 10-bits and it doesn’t work with HLG. Stay tuned.
