Details
In a multi-port input configuration, the projector requires all signals to have a stable sync. The
projector automatically selects the top-left signal as the master signal to use as reference. If the
master is unstable, all of the other signals look unstable. Possible symptoms of the issue include:
•
Non-master signals constantly locking and unlocking
•
Dropped frames in the affected sections of the display
•
Tearing in the affected sections of the display
Possible root causes include the master signal or non-master signals not having stable syncs.

Solution
Change Slot 1 Input 1 cable (master) with the Slot 3 Input 1 cable. If the master signal is the issue,
only Slot 3 Input 1 should show the lock/unlock symptom. If the video source is the issue, the
symptoms should remain the same.
Screen has reversed colors
The screen has reversed colors (such as the blue and green are swapped) and the Formatter
Mismatch alarm appears in the Status tab of the TPC. For example:
Formatter - Green HW Version
Formatter - Blue HW Version
Details
The formatters are not connected correctly to the high speed image processor board (HIP)—the
above example illustrates the green and blue formatters.
