Hi all wise post folks
new (identical) rig, Blackmagic Ultra Studio Monitor 3G not working to a (known to be good) HDMI in. (consumer tv)
I did just install the "Desktop video 12.3 (Mac) and no luck
running Catalina (latest) and ProTools Ultimate 2021.12
ProTools is fine, and it is showing video files IN protools just fine....
(known to be compatible video files with Blackmagic Ultra Studio Monitor 3G as I ran same video on my other, far away, identical rig)
yes rebooted.
what am i missing?
thanks!
