Set Polarity Mode
It is possible that the 3D image, although perfectly clear and free of ghosting, looks incorrect or shows
no depth. The polarity could be reversed, which means the left lens is open when the right eye image is
being displayed – the left eye is getting the right image and vice versa. Simply place the glasses upside
down over your eyes to check if the image is now corrected. If the 3D image is better, the polarity is
reversed. Reversal of polarity can be caused by the source, the content or the projector. The source
equipment or the 3D ready projector may have an option to correct this. If not, the Optoma 3D-RF
Emitter can be used to reverse polarity.
