usb c monitor not working with Tahoe 26.3
 

I have a usb c monitor plugged in through my dell UD22 dock to my MacBook Air. the laptop is n Mac OS 26.3 and recognizes the display and the display receives signal when I boot the computer with the dock plugged into my laptop but if I unplug and replug, the MacBook still recognizes the display but the display no longer receives signal from the Mac.. works still with my Mac OS 26.2 laptop

Hello,

USB-C monitor output of UD22 doesn't use DisplayLink technology (this product is kind of a hybrid solution). For any potential updates of this functionality, please check UD22 FW updates published directly by Dell:

The latest version as of today is 1.0.17.23, A07, unfortunately, it requires Windows to perform an update.
