Users of our UD-ULTCDL and UD-ULTC4K docks can continue to drive a single monitor connected to the 4K “Alt Mode” HDMI output on their dock. With this OS change, the total number of displays that can be connected to Thunderbolt 3 and USB-C Macs is now significantly reduced.


This loss of functionality is a frustrating development for those of us who have become accustomed to multi-monitor goodness as part of our daily workflow.
