444,10bit so long as you are using a 18Gbps High Speed HDMI 2.0a cable like the Amazon Basics or the Monoprice Premium Certified ones.

I'm having a challenge setting my minix u9-h to output at 444,10bit using the commands earlier in this thread (or any 10bit setting in reality).

Both my TV (OLED65E6P) and AVR (RX-V679BL) are capable of 444,10bit, but when I reboot the minix fresh, issue the command "echo '444,10bit' > /sys/class/amhdmitx/amhdmitx0/attr" and play a 4k HDR file, my TV says that no source signal is connected, and I get no sound either.

The same thing happens with all other 10bit combinations with the exception of 422,10bit, which gives me sound and video with a green tint to everything (which I read you mentioned is related to the current kernel). 

Is there something that I am doing wrong? All of my HDMI cables are 'High Spped HDMI cables w/ Ethernet', which I read indicate an HDMI 2.0a cable. Other than switching out the cables (which I will do, just ordered a new set), is there anything else that I could be missing here?

Thanks
