Quadro sync II genlock reliability issues.

Recently me and my team have been having issues with Genlocking our single-node NDisplay setup (a6000, quadro sync II).

We have one editor machine connected to a multi-user session with our render node, controlling video playback via Sequencer.

Despite the GPU being Genlocked to our AJA10 Sync Generator, the signal seems to sync out every now and then. Especially when playin/pausing our plate in UE.

We have a few theories as to why, but we believe it’s because the AJA is sending a PSF signal.

Have any of you ever worked with a GEN10 on a PSF signal? How was the stability?
