It's been a while since I tried a broadcast monitor for AE previews. I'm looking at a Decklink mini Monitor 4K so I can use SDI to get to a Flanders monitor I have here. In the past, I always had issues getting AE to play back realtime when an external monitor was connected. It felt as if the external monitor was a huge strain on the system. I thought I'd get a consensus before I use hard earned budget dollars.
