Please be aware that enabling this feature will also affect the SDI loop jitter. The device will not be
SMPTE compliant.
In some cases the SDI input jitter exceeds the SMPTE
specification which makes the status LED to switch
between green and red (see section 3.2). This
normally causes the monitor to lose sync. To avoid
this erratic behavior you can enable this feature.
If the problem persists you should identify and fix the
source of the excessive JITTER.
