I have now my Arches Canyon NUC and the following problem:
(i have setup the display to 1920x1080 (3D) and the 3D switch to on)

Every time, when i'm playing an MVC video, the TV switches to the half res 1920x512, and the picture is overlapped. If i switch manually to over/under, than the 3D is OK.

Any hints?

Check that Intel settings refresh rate set at 60hz,

Yes, it is.

and that hardware base is selected.

I don't understand that, do you mean a KODI setting for decoding 3D streams (MVC)?

KODI switches to hardware 3D and the TV also, but changes the resolution to 1920x521 instead full resolution. The picture looks like the same, if you switch the TV manually on a 2D picture to over and under. the behavier is with the setting "use fullscreen windows". If i switch this off, the screen remains on 3D files blank and even the sound is muted. On 2D files all plays fine.
On the same HDMI cable a RPi works fine.
I have also another problem - i get only DTS sound, on DTS-HD or Dolby TrueHD the sound is muted. I have to switch of these options off to get the at least the core DTS sound.
I'm using the drivers from Intel Driver Tool.
