Blackmagic Forum

Hi,

here's what I found after quite some testing, to get the Ultrastudio Monitor 3G to work with my Macbook Air M2:

- check cable -> USB-C 4?

- give permissions for Blackmagic soft- and hardware in macOS 'privacy & security'
- re-set macOS legacy settings:

- check Blackmagic Desktop Video App: does it recognize the Ultrastudio Monitor? if yes - done...

- check if you find the Ultrastudio Monitor 3G listed as connected device in the MacOS system report ('hardware / thunderbolt/USB4'). then do the following:
- update the Ultrastudio Monitor and 'kickstart' the Desktop Video App:

Worked for me. Thanks to the forum!... Jan

I believe you need to use Thunderbolt cable. None of my existing USB cable had worked with UltraStudio Monitor 3G.

I also noticed that if I want to output HDR data I should set no higher than 1080p25 otherwise it won't send HDR

The light on it doesn't even turn on for me if it's not a Thunderbolt cable.
