Appendix A: Troubleshooting

Refer to the following guide if 3D images image displayed by your projector
do not appear as you expect:
: Increase the incoming frame rate to at least 96 Hz.
FLICKERING IMAGE
: Increase pixel tracking. If already

maximized, the pixel clock rate of the source is too high for the projector.
: 1) Make sure the IR emitter is not blocked and
3D CROSS-TALK (GHOSTING)
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.
: Your video card's
NO IMAGE, JUMPY IMAGE, OR NOISE AT IMAGE TOP
minimum timings for blanking and pulse width may be too slow for use with
the projector. Try adjusting the timing parameters in your source.
: You are not in 3D mode.
WITHOUT GLASSES, I SEE ONLY A SINGLE IMAGE
: The 3D Stereo Sync

Cable may not be connected properly. If the cable is connected, the 3D
Stereo Sync setting in the Advanced Image Settings menu needs to be toggled
(inverted from its current setting). If you are not using the 3D Stereo Sync
Cable, refer to the documentation for your 3D card or application.
: The horizontal back porch may be too small or too

large. If you can lock to the signal by changing H-Position but have a black
left edge in the image, reduce the source's horizontal back porch blanking. If
the black edge is on the right, increase the source's horizontal back porch
blanking.
: You may need to adjust the Clamp

Location option in the Input Levels menu (accessed via Image Settings menu)
with 4- or 5-wire signals.
: If some grays in your grayscale appears tinted when

viewed in 3D, your glasses may be slightly slow for the current signal setup.
1) If possible, adjust the projector's Dark Interval control. 2) Double-check
timing adjustments to the source. 3) Use faster glasses.
: for example it changes to cooling

down state when the output is plugged in. Ensure that GIO port parameters
are clear and that there are no Real Time Events (RTE) that change GIO port
parameters. Refer to the Serial Communication guide for more information.
