Hi ChrisBrearley,
Sorry for the delay in contacting you once more. Your response appears to have slipped by me, but I'm circling back now to see if anything positive occurred. Sorry for that.
Hi Kevin, thank you for your reply. I've spoken with two support agents from Adobe about this issue and both suggested that it was not a problem with AE but with the Blackmagic card. Unfortunately I don't have case numbers for these conversations.
I have tools that I can use to track your case down. I should be able to correct the issue from my side. That said, I need to find out where they are getting their info from, as there are no bugs logged here that I could find indicating the issue.
The source footage has nothing to do with this problem. In face there doesn't need to be any footage in the comp. A 10x10 white solid animating across screen will still lag.
Thanks for detailing the issue.
Playback on the main monitor is fine, the issue is with how the mercury playback engine in AE sends the
image to the Intensity 4k.
I have also unsuccessfully tried to use one of my 980Tis as the output but again there are serious issues with anything
above HD. There is still lag and the image doesn't fit the screen correctly.
I would love to know if anyone has had any success in outputting to an external monitor through any device with a comp size above HD.
See if Szalam's advice might help here regarding Display Preferences: Re: After Effects CC 2017 very laggy on second monitor
I have filed several bug reports and feature requests over the years but not once have any of them been acknowledged or actioned so I have given up.
That's frustrating. Sorry about that. Not all feature requests do get implemented, however, for a number of various reasons. I do not like that we don't acknowledge feature requests, but the answer to that is that we simply do not have enough time to do so for every case. We do reach out to select customers for clarification, though. So it does happen, just not very frequently.
I have been in touch with Blackmagic since and they have been able to replicate the problem at there end.
Thanks. Let us know if they follow up with any new info.

I am hoping that the engineers there have a direct line with Adobe and are able to get there heads together and figure out what is going on. This was a few weeks ago but I have heard nothing since.
We have a standing relationship with all our partners. Since there is no bug filed from our side that I can see, and our partner is seeing a bug, I will have to reconcile that for all parties by filing by own bug. I'll see to it that it gets filed from our side. Any other info we could receive from you via a bug report would be ideal, that way, we can hit the issue from both sides.
Sorry again for this frustration, but I'll do my best to get the ball rolling on this issue. Thanks for keeping the communication going.
Kind regards,
Kevin
