Premiere Pro v22 (b169) I am unable to monitor HLG sequences (either HD or UHD) with HLG content thru a Decklink 4K 12G (ver. 12.2.2) . The monitor "sees" a signal but remains black, reporting UHD HLG with a BT.2020 gamut. If I toggle the sequence's Working Color Space to Rec709 an image appears and the monitor switches to Rec709 and drops out of HLG. The same thing happens if I toggle the Decklink's color gamut preferences to Rec709 within Premiere's Preferences/Playback/Video Device settings. So I know the Decklink is sending a signal.
The same UHD HLG content plays back flawlessly thru Blackmagic's Media Express software.
I've run out of things to try, switches to flip. In case you're wondering, I dont have a HDR monitor with SDI inputs so I can't try that.
