Our suite is running the latest version of Premiere 23.2.0 - We playback visuals via the Blackmagic Extreme 3 to an extenal Atomos Neon 24 via SDI and also to a LG OLED via HDMI from the Blackmagic Extreme 3.
The LG OLED is lagging behind by around half a second from Premiere and the Atomos Neon.
I've checked playback with Davinci Resolve and the TV is in perfect sync with Resolve and the Atomos Neon.
The issue appears to only present itself with Premiere Pro. We have another suite (PC) running the Extreme 3 using the same model of TV with the same issue.
I can't see any settings via playback or Desktop Video (Blackmagic) to correct this.
I've been in contact with Blackmagic support who are investigating.
I've attached two videos showing the lag with Premiere and the correct sync with Resolve.
