Just got CAC-1586 including CAC-1371 to connect my Mac Mini M1 connected to LG OLED48C11.

Reason I got CAC-1586 was to enable HDR and 10bit, 4:4:4 color on 4k which is not happening. I can either get 4k 60Hz SDR with 8bit 4:4:4 or, 4k 30Hz SDR with 10bit 4:4:4 but 4k HDR always go to 8bit 4:2:2.

What can I do to fix it? Or is this adapter not supported? Thanks!

I have the same issue, but with a MacBook Pro Max 10c/24c/32g/1tb.
