Hello everyone,
recently I played around with my kabylake i5 nuc box and found that on some
TV's
the screen stays black as soon as I go to 4k@60.
The TV only accepts 4k@60 at yuv 4:2:0 (I also saw hdmi range extenders and
stuff that don't support yuv 4:4:4 on 4k@60).
I tried to force limited mode through xrandr or by overriding the edid
information, but nothing worked so far.
Now I wonder if there is a way to force yuv 4:2:0 ouptut on the kernel
level.
Thanks.
Kind Regards,
Wolfgang

I've tried v4.14-rc1.
Now I do not have 4k@60 anymore.
dmesg with drm.debug:
