Dear Adobe,

I run a post-facility of six Premiere Pro edit suites, all iMac based, connecting once to a secondary working display and once again using TB2/TB3 Ultrastudio Mini Monitors to connect to a reference display.

I can see and feel a clear difference in playback latency when turning on or off the transmit playback monitoring to the reference display. With transmit enabled the latency when pressing play is measurably higher than if it is turned off. This is slowing down our work enough for me to just want to disable the reference monitor altogether.

We are running the latest driver release from Blackmagic Design on the latest Premiere Pro release right now. This problem however has been consistent over every version of the driver or Premiere Pro. I am not sure if it is the hardware, the drivers or Premiere causing the issues. It would however be fantastic to see it cleared up. Thanks!
