    Hi,

    I use the Egreat H10 with a Minix Amlogic S912 media box and CoreElec.

    I have tried to output 4k@60hz 444 10bits signal through the Egreat H10 but it does not work.
    The TV (LG E6) works if I connect the media box directly to it.

    When I list on the media box, the capabilities of the connected Egreat H10, I see :
    CoreELEC:~/.config # cat /sys/class/amhdmitx/amhdmitx0/disp_cap
    480p60hz
    576p50hz
    720p60hz
    1080i60hz
    1080p60hz
    720p50hz
    1080i50hz
    1080p30hz
    1080p50hz
    1080p25hz
    1080p24hz
    2160p30hz
    2160p25hz
    2160p24hz
    smpte24hz
    smpte25hz
    smpte30hz
    smpte50hz
    smpte60hz
    smpte50hz420
    smpte60hz420
    2160p50hz
    2160p60hz
    2160p50hz420
    2160p60hz420

    ==> there is no 444 10 bits mode listed;

    Remark: the media box is able to do 444 10bits:
    CoreELEC:~/.config # cat /sys/class/amhdmitx/amhdmitx0/dc_cap
    420,10bit
    420,8bit
    444,10bit
    444,8bit
    422,10bit
    422,8bit
    rgb,10bit
    rgb,8bit

    ==> the problem is neither the media box (nor the TV)

    ==> Can you upgrade the firmware so that we can use a 4k@60hz 444 10bits signal ?

    Thanks
