the frozen screen in the device.
Genlock
When the frame rate of the output is the same or two times with the frame rate of the EXT. SYNC,
the Genlock function can be locked. The Genlock function also provides the “Horizontal Offset”
and “Vertical Offset” function for your adjustment which are shown as following diagram.
Horizontal Offset: The adjustment range is +/- 5500 Pixels
Vertical Offset: The adjustment range is+/- 500 Lines
For the status of the Genlock function, the word “Locked” will be shown when it is locked.
Note: The Genlock function will be locked only when the Genlock function is turned “ON” and the
output resolution is the same or two times compared to the frame rate of the EXT. SYNC.
Otherwise, the word “Unlocked” will be shown.
For example, if the input signal of the EXT. SYNC is PAL (frame rate is 25) and then it can be locked
if the output resolution is 2160p50 or 2160p25. Moreover, it can not be locked if the output
resolution is 2160p60, 2160p30 or 2160p24.
