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.
For more details, refer to the following:

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.
