Colors in the image are
swapped; for example, reds
appear blue or vice versa.
• The Red/Pr, Green/Y or
Blue/Pb outputs from the
source are connected to
the wrong inputs on the
3Dimension Processor.
• Ensure that the source
outputs are connected to
the correct 3Dimension
Processor input.
RGB-HD or Component HD
images appear “noisy” or drop
out intermittently.
• Tracking and Phase
settings need adjustment.
• The DHD Controller is
having difficulty detecting
sync pulses from the
source.
• Adjust Tracking and Phase
settings (refer to Input
Position on page 74).
• Adjust the Sync Threshold
setting (refer to Sync
Threshold on page 93).
Computer images do not dis-
play correctly.
• The resolution and
frequency of the video card
in the computer are not
compatible with the D-73d.
• Select a compatible
resolution and vertical
frequency (refer to
Supported Timings on
page 120).
Images from an HDMI source
do not display.
• The resolution and
frequency of the video card
in the computer are not
compatible with the D-73d.
• EDID compatibility issue.
• HDMI cable from source to
3Dimension Processor is
either defective or too long.
• Select a compatible
resolution and vertical
frequency (refer to
Supported Timings on
page 120).
• Set HDMI EDID Extension
to “Off” (refer to HDMI
EDID Extension on

receiver with audio delay
capability to synchronize
the audio signal with the
video signal.
The image is too large or too
small.
• Image size needs adjusting. • Adjust the image size (refer
to Input Position on
page 74).
When displaying 3D content,
crosstalk or “ghosting” can be
seen — that is, the left eye is
perceiving some of what the
right eye should be seeing or
vice versa.
• Primary and Secondary
images are not properly
aligned.
• Rear-projection installation
uses second-surface
mirrors that are producing
faint, secondary reflections.
• Screen is not
3D-compatible (refer to
Choosing A Screen on
page 24).
• Refer to Power-Up
Sequence and Optical
Alignment Procedure on
page 51.
• Always use first-surface
mirrors in your
rear-projection installation.
