Like I said ... enjoy the 3D format, however, it's not FULL HD 3D, otherwise it would not pass through the 2808.
This from the Mitsubishi site ...
Checkerboard — The Checkerboard format is really designed as method of displaying 3D on the TV and is not one of the HDMI 1.4a 3D signals
. However Checkerboard signals can be transferred over normal high speed HDMI cables. The Mitsubishi 3D TVs display 3D using the checkerboard format so the Mitsubishi 3D Adapter is designed to convert the Frame Packing, Side-By-Side and Top-and-Bottom signals mentioned above to the checkerboard format.
from another site which indicates the Mitsu DLP TV's can only display "Half full-3D HD."
