I've just discovered Kodi DSPlayer, don't know how I missed it, but in any case it's totally awesome!

I see that some madVR settings can be configured via the Kodi GUI. My setup has my HTPC with Kodi connected to a HDMI switch which connects to both a TV and a projector. I'd like to use a different 3D LUT table in madVR for these two output devices. Unfortunately in madVR settings, the HDMI switch is shown as a single output device, and the TV/projector is "hidden" behind it.

Is there any way of switching 3D LUT files in madVR via the Kodi GUI?

The best you could do is toggle the 3D LUT on and off by remote. There is a keyboard shortcut in madVR available for this purpose.
