@accolon, create a file called disp_cap_3d
in the /home/osmc/.kodi/userdata
directory and add these lines to it:
1080p24hz FramePacking TopBottom
1080i50hz SidebySide
1080i60hz SidebySide
720p50hz FramePacking TopBottom
720p60hz FramePacking TopBottom
then reboot your Vero and test again. Let us know if anything has changed.
Note: these lines tell Kodi which 3D resolutions are supported. If that file exists it overrides information from EDID. So it might still be the case that your projector can’t show the video because it simply does not support that resolution.
