I'm sure this has already been discussed, but if someone directed me to some info on what's causing the lack of picture in VP 14 Preview Monitor (GUI window) I'd appreciate it. As can be seen in my sig, I have 2 GTX 1080s (used as accelerators) and the Decklink 12G (used with external monitor for full-screen preview). I can only use external preview (either Decklink or on the Windows Secondary Screen through one of the GTX'es) - the internal preview window is always black, unless I remove nVidia card from my Preferences=>Video tab... Thank you,
Piotr
