unable to select 1080p30 or other refresh rates ODRIOD-C2

    I only have: /sys/devices/virtual/amhdmitx/amhdmitx0/disp_cap

    720p60hz
    1080i60hz
    1080p60hz
    720p50hz
    1080i50hz
    1080p50hz


    However I truly need 1080p30hz as 50 and 60hz have issues over long runs (and almost no video is 60hz), so I really need:

    1080p30hz
    1080p24hz
    1080p25hz
    1080p23hz

    Now the EDID is being provided by a Genfen device so I know all of these are present, but since the disp_cap does not include them I can not select them in the UI.
    Since my HTPC finds all the modes using the same genfen it must be properly reporting the display modes , there was at one time a chek that allowed over-ridding this it appears, but it does not seem present any longer.

    How do I get LibreELEC to provide a full set of resolutions and refresh rates that should be present, even if I have to force it.

    I've managed to get it to show 1080p60 and 1080p24, but that is it (only 2 ever), which is not usable.

    Thanks,
    ERIC
