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
Dimension Digital
Controller is either
defective or too long.
Select a compatible
resolution and vertical
frequency (refer to

page 95).

shorter HDMI cable.

capability to synchronize
the audio signal with the
video signal.

small.
Image size needs
adjusting.
Adjust the image size
(refer to Input Position on

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.

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.
Install a 3D-compatible
screen.

doesn’t work.
The motor is not plugged
in or the AC outlet is not
active.
The motor is not
connected to the trigger
output on the projector.

plugged in and that the AC
outlet is active.
