There is a BIG probleam with x8 and x9s about HDMI output at 10bit. Select 422 as color space and 10 bit deep color my A/V reciver report 24 bit not 30 bit (10*3), 1080 and 2160 resolution have same problem. Also on color space setting is missing YCbCr 420 as option , WHY? This is a very big problem for a "UHD player" because UHD video are YCbCr 420 HEVC 10 bit . I hope is fix asap as is possible.
