If you are having trouble seeing 3D, Try changing the 3D selection types if it is difficult to determine what format
the 3D movie is in. Example: Top/Bottom, Side by Side, Checker Board, Frame Sequential.
Make sure you are using at least version 1.3 HDMI cable. (1.4 HDMI will auto select).
Play a 3D Movie
A simple test is to hold the glasses about 1 ft. in front of you towards a white sheet of paper.
The TV must be playing a 3D movie and be in the 3D mode.
If the glasses sync up the paper will appear as looking through normal sun glasses,
if not synced, the paper will appear amber in color.
Don’t forget to try swapping the L/R selection by pressing the
“Quick Menu” button on the remote control.
