 Topic: X670E + Thunderbolt 4 AIC + Apple Cinema DisplayPosted: 20 Nov 2022 at 3:46am |

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?
