Tri-Sync - Decklink 4k Studio Reference in with System Clock/Video Output

Hey everyone,

I have a setup which includes a Decklink Studio 4k which has a SDI Reference IN which can - as the blackmagic website describes - use the following sync options:

Sync Input:
Blackburst in SD, 720p50, 720p59.94, 1080i50 and 1080i59.94 formats or Tri-Sync in any HD, 2K or 4K format.

Is it possible to grab the Input from this reference In to sync the computer with a video mixer to which it gives multiple dvi outputs via its R295X2?

thx for your help
