NUC / Core i5 8250U (Kaby Lake Refresh) / UHD 620 / No 4K on HDMI output

Hi all,


I'm almost there on this config:

- Intel Core i5 8250U

- Ethernet: RTL8111 (working)

- Audio ALC892 (working)

- HDMI+VGA outputs (working, even HDMI audio)


Only thing missing is 4K on HDMI output, for some reason my LG TV is detected as 1080p only, though when booting on a Live Ubuntu I have 4K on the same unit.

Any clue ? Should I dig for EDID injection or some similar stuff ?

Here is the device-property area of my config.plist:


I'm running Lilu 1.4.2 and WhateverGreen 1.3.7

I have testes Switchres, but 4K res does not show, and max proposed resolution is 2560x1440 but it looks scaled from 1080p.

Any help appreciated, if I need to provide more info please let me know.
