A Boxx Meridian broadcast receiver showed approximately 50 lines of delay relative to the main frame despite timecode alignment and genlock synchronization being confirmed
Using a framestore to compensate for synchronization delay introduces an additional full frame delay as a side effect
Genlock delay adjustment on the receiver had been verified at zero setting during troubleshooting
Technical support recommended testing the system specifically in SD SDI mode to address the synchronization issue

The discussion involves a specific 2014 broadcast setup and may not apply to current systems or different signal formats
No final resolution or recommended configuration was documented in the thread
The exact cause of the 50-line delay was not definitively identified
