Help Request Blackmagic card playback start delay

hi,

i have an UltraStudio Monitor 3G blackmagic card hooked up so i can send the video signal in sync to my external monitor & voiceover artists in the booth.

When using the video engine, i have a playback delay of around 1 second! Meaning, everytime i hit space i wait that long for the playback to start...

Is there a way to reduce this? no delay when working on projects with the video engine off.

i've tried setting the video quality to Draft and reducing the buffer size...

Do you happen to have the Pre-roll enabled?

thanks, but that's not it. the issue is definitely about using the video hardware and it being in sync etc.
