Troubleshooting
This document provides information and procedures for resolving common projector issues. If a
projector issue cannot be resolved, contact Christie Technical Support.
Missing image quadrant with TDPIC
When Twin DisplayPort Input cards (TDPIC) are used in a Four Port Input configuration using the
AMD FirePro™ graphics card as the source, one or more quadrants may be missing.
Details
This issue has been traced to the graphics card failing the DisplayPort link connection, which results
in the graphics card driver dropping the signal.
Solution
The latest AMD driver corrects this issue. Contact your video source vendor for an update or
download the driver directly from AMD.
Signals fail to lock on Four Port Input
configurations
The projector fails to lock onto non-master video signals for a Four Port Input configuration.
ELECTRICAL SHOCK HAZARD! Always turn off, disconnect, and disengage all power sources
to the projector before servicing. Failure to comply results in death or serious injury.
Only Christie accredited service technicians are permitted to open any enclosure on the
projector and only if the AC power has been fully disconnected. Failure to comply could
result in minor or moderate injury.
