If one isn't it may not have enough bandwidth to pass all of the data, this is a real blind guess but I've seen enough cheap HDMI cables cause problems to at least suggest it.
I would also try connecting the device directly to the TV to see if you get full HDCP audio/video without the AVR in between. That would eliminate the AVR at least. Good luck!
Thanks for the suggestion on this. I figured it out. First I just switched the port, but then I began thinking more about it and I think you are correct in terms of the bandwidth of the HDMI cables. I didn't switch them but I did go into my AVR and switch the 4K mode. from Mode 1 to 2. The difference being Mode 1 is as follows:
Inputs/outputs 4K (60 Hz/50 Hz) signals in 4:4:4, 4:2:2 or 4:2:0 format.
(4:2:0 format only for VIDEO AUX [HDMI/MHL IN] jack)
Depending on the connected devices or HDMI cables, videos may
not be displayed correctly. In this case, select “MODE 2”
MODE 2 (default) Inputs/outputs 4K (60 Hz/50 Hz) signals in 4:2:0 format
• When “MODE 1” is selected, use a high-speed HDMI cable that supports 18 Gbps.
So I'm guessing it is the cables. Funny thing is that the X900B doesn't require this which is why I didn't think of it. But I don't think the X900B accepts 4:2:0 in 10 & 12bit and then higher chroma will do the 4:4:4, 4:2:2 but it must not have been full bandwidth and probably in 8bit. Where the AX800 is does full bandwidth
So I will have to check out new cables.
and see what happens. Will test all my devices with the mode on and see what happens and go from there. or I could just buy a bunch of HDMI cables in bulk since Im running low anyways and replace all of them
