Thanks. That’s what it was, sort of. I don’t run a second OS display but at some point recently (ikely when I was configuring a new broadcast monitor) I must have had that set and the “HDR Extended Display” was checked. As this is only visible if you have an extended monoitor set up, I missed it. I set up a second display, changed the Flame Set up and now I’m good to go. Thanks @Francesco.Bianco !
