Phase Off check box
The Phase Off check box determines whether panels are
phase-synchronized (genlocked) to the selected signal. When
checked, panels will be frequency tuned only when you perform
the tuning procedure below. This may provide better performance
if the sync signal is irregular or unstable.
DVI / External Vsync radio buttons
These radio buttons select the synchronization reference signal.
• To synchronize panels using the signal at the BNC connector, select External Vsync.
• To synchronize panels using the DVI signal, select DVI.
Tune button
Clicking Tune causes LCS to calculate the optimum refresh frequency based on the selected
synchronization signal.
To tune the video refresh frequency:
1. Click on any panel in the grid display.
2. Select a signal source: DVI or External Vsync.
3. For genlock synchronization, remove the check from the Phase Off check box. When checked, panels
are frequency tuned only.
4. Click Tune. The DVI signal and panel refresh frequencies are displayed as the process runs. If the “No
Panel” message appears, select a panel and try again.
5. Allow the tuning process 2 to 3 minutes to complete. The Tune button changes back to light grey when
tuning is completed.
6. Click Save Parameters to save the refresh frequency in each panel’s non-volatile memory.
300 Hz button
Clicking 300Hz resets the panel refresh frequency to approximately 300 Hz. This may be required if the
panels cannot be tuned because the video input is unstable or missing.
C o n n e c t b u t t o n
Click Connect to refresh the grid display anytime, after changing address settings, and to display the
panels’ firmware version numbers.
