Hello,

I have a Dell Precision 3581 with WD22TB4 dock, after upgrading to Windows 11 Thunderbolt stopped working. It looks like the dock is now running an alternate mode (USB-C) which means one of my two 4k displays is limited to 30Hz.

Thunderbolt Control Center is now showing nothing - no WD22TB4, no available ports.

Of course, all available drivers and firmware updates are installed and up to date.

How can I get back to 2*60Hz for my two 4k displays?

Greetings,

Hauke
