Synclock to live video

[markcarman]

I am using a SDI video capture card (Blackmagic Decklink Quad) to display a live video window on an LCD monitor.
I have noticed the video jumps about every 12 seconds when the LCD is set to 60hz (the video runs at 59.94).
I have used CRU.exe to try and force the LCD to run at 59.94, and this seems to make it much better, yet it still drifts every 30-40 seconds now.
Short of using a $4k Quadro 4000 Sync graphics card, does anyone have n idea of how I can make the gfx card refresh more stable?

I don't know of a way to synchronize the refresh rate with live video. I think you would need hardware with genlock capability for that.

Thanks. I need to start searching.. Quadro makes a card but the price is crazy!
