    I have z9s and notice that color chroma subsampling 4:2:0 disappeared.
    Last firmware 2.3.35 .
    Tried reset and the option appeared but after restart disappeared.
    Any ideas?

    Can you post a screen shot of the 4:2:0 options missing?

    It depends on the HDMI mode as to what options appear.

    4:2:0 is only a legal HDMI mode at 50/59/60Hz. If you set "HDMI Mode" to either 50 or 60Hz you'll see the 4:2:0 option, otherwise you won't since it's not a legal mode.

    So when you did a reset, the HDMI Mode reset to Auto and your EDID dictated 60Hz so that option appeared. Presumably you then set back to 23Hz and it correctly disappeared.
