Hello, does anyone have any experience running an Apple Cinema Display MC914LL/A - A1407 via the Thunderbolt 4 expansion card? The display has a Thunderbolt 2 connector with an Apple thunderbolt 2 to thunderbolt 3 adapter. This setup works as it should while running [bootcamp] windows on my Macbook. It should work with my new build.

However, the expansion card displays a yellow exclamation mark in Device Manager "UCM-UCSI ACPI". My board is an X670E Lightning and my processor is an AMD Ryzen 7950x. Any suggestions or expertise is gladly welcomed

Can you confirm that the Thunderbolt AIC is working properly? What make and model Thunderbolt card are you using (ASRock)? Can you test the Thunderbolt AIC with another Thunderbolt device?
