User’s Manual

When using a 3D Stereo Sync cable at the Mirage GPIO port, select which 3D Stereo

Sync input (A or B) is connected, adjust the 3D delay, and choose the 3D Stereo Sync

locking/inversion options applicable for your installation. See below.

The following sources are optimized for active 3D (stereographic) images using the

projector and active glasses. Clamp Location is “Back Porch”. Keep in mind that

formats beyond those shown below may also be compatible.

Refer to the following guide if 3D (stereographic) images displayed by your projector

do not appear as you expect:

FLICKERING IMAGE: Increase the incoming frame rate as much as possible.

IMAGE IS COMPRESSED HORIZONTALLY: Increase pixel tracking. If already

maximized, the pixel clock rate of the source is too high for the projector.

3D CROSS-TALK (GHOSTING)

: 1) Make sure the IR emitter is not blocked and that its

signals can reach glasses. 2) If using a Pi Cell polarizer and passive glasses, make sure you

are using a screen that maintains polarity. 3) Are depleted batteries slowing down the

active glasses? 4) Fix timing parameters in your source. 5) Adjust Dark Interval setting.

NO IMAGE, JUMPY IMAGE, OR NOISE AT IMAGE TOP: Your video card’s minimum

timings for blanking and pulse width are too slow for use with the projector.

WITHOUT GLASSES, I SEE ONLY A SINGLE IMAGE: You are not in 3D mode.

WITH GLASSES, PERSPECTIVE APPEARS “REVERSED”: If vanishing points of objects

appear in the foreground rather than background, destroying perspective, the TTL

inverter is likely missing or not working (you can confirm this by turning the glasses

upside-down—3D perspective will return). Or, if you are using the 3D Stereo Sync

Cable, the 3D Stereo Sync setting in the Advanced Image Settings menu needs to be

needs to be toggled (inverted from its current setting).
