Auto resolution switch between 1080p and 1024x768 - Possible?

We still have the force_rgb parameter and we could probably reset that during the Kodi HPD event trigger as a cheap hack. We would be dependent on Kodi running however…

I’ve just been looking at that. We could probably force 8 bits whenever RGB is used.

Yes – we can just check that flag each time.
I wonder if the current HPD process is sufficient though – does it fully probe the disp_mode_auto() pathway?
