On Pi if you have "Use full HD HDMI modes for 3D" then when outputting 3D we will use a framepacking HDMI mode (e.g. 1920x2205) with full resolution for each eye.
The GUI is always rendered as half-SBS or half-TAB for performance reasons, but the video will be full resolution.
E.g. if you play an MVC video you will get 1920x1080 pixels for each eye.
You can confirm the HDMI mode with "tvservice -s" which will show "FP" when outputting a framepacking mode.
If it shows that we will unconditionally be outputting a framepacking (e.g. 1920x2205) mode.
Try connecting to a TV that doesn't support 3D to confirm - you won't get an image for FP but you will for half-TAB/half-SBS (when "Use full HD HDMI modes for 3D" is disabled).
