Intel NUC11: Blank display for all 4K content. Help please?

    LE 12 Beta1 build in all tests below, with 4k resolutions 'white' listed, latest firmware (same issues with all recent nighlies)

    I have a NUC11TNKi3 which works perfectly with latest Denon AVR4800H with LG CX 4k TV.

    Same NUC11TNKi3 with my Denon AVR3400H and Sony A8F 4K TV plays everything except 4K (always shows blank screen for any 4K file) and is completely unresponsive. Both AVR and TV are HDMI 2.0b

    My old NUC8BEHi3 with my Denon AVR3400H and Sony A8F 4K TV plays everything including 4K perfectly.

    Looking at the NUC11TNKi3 logs there is an EDID error:

    Can anyone help me to resolve this issue please?

    After attempting a EDID fix I accidently discovered a fix:

    Remove '3840x2160 24Hz' and '23.976' from whitelist and set both Kodi's 'Allow 3:2 pulldown' and 'Allow Double Refresh Rates' to ON (Enabled).

    Now everything playing.

    (The accidental discover after I reinstalled LE12 from scratch I found 23.976 played and 24Hz did not, I had forgotten to Whitelist 23.976).
