5.1.2 Delay Ghosting and Fuzziness
When MAX 3D Eyewear is attached to certain 3D TV systems, some ghosting or fuzziness may appear.
This is unlikely to occur when the IR receiver is used.
Ghosting and fuzziness appears when there is a delay between the 3D emitter port and the alternating
light emitting from the display. This delay between display and eyewear causes some of the left eye’s
image to “bleed” into the right eye and vice-versa, yielding a ghost or faint double image on the display.
In this case, since the video signal is delayed at the display, more delay must be added to the 3D
emitter signal so that the signals match again. See section 5.4 Adjusting Delay on pg. 25.

In engineering terms, the total time of one left frame and one right frame can be measured as
360 degrees. The delay control is centered at no delay and can add zero to 90 degrees. To add 90 to
180 degrees of delay, push the joystick to reverse and then adjust delay again.
