In my studio, I hear audio about 2.5 frames sooner than picture on my projector. Clients are always mentioning sync feels off. Both image and sound are output via SDI via a Decklink Mini Monitor 4K.

I really want to be able to input a software audio delay in the global Resolve preferences to rectify this. Pro Tools makes this dead simple with a menu option.

Better yet, it'd be great to have an audio offset in Desktop Video itself, to ensure sync is compensated for in Premiere as well.

From what I've read on the Internets and from personal experience, it seems like a few frames of video delay are common with Mini Monitors / Ultra Studios. How can there still be no way to adjust this?

What is the delay between your speakers and the UI viewer?
I presume you are not using system audio, can you detail the monitoring path?

This is a long-standing issue -- I'm off about 3 frames, via Decklink HDMI, with analog out from the monitor looped back to the receiver. The same setup, with HDMI from the gtx card, is in sync.

System audio is also out of sync with UI, by two frames.

Going through something like VLC, sync is frame-accurate, with both system and GTX audio.

OP: Voxengo has a free sound-delay plugin. You can put it in the main output in the Fairlight page, for each timeline, if you don't have a hardware delay available.
