Plugable’s updated UD-3900 is an improved docking station, but has its limitations

And Plugable has upgraded its the universal docking station that allows users to expand their laptop into a full workstation. 

This docking station has been one of Plugable’s top docks for years, but has upgraded and is now compatible with Thunderbolt 3, Thunderbolt 4, USB4, USB 3.0, or USB-C laptops

UD-3900 Disadvantages

One slight disadvantage for Mac users compared to Windows uses is that you’ll have to manually install a driver. The Plugable UD-3900 doesn’t just work with Macs out of the box. 

And there are other disadvantages. The Plugable dock isn’t recommended for gaming via its “mere” 60Hz refresh late. That said, Plugable notes that it’s designed for use with web and productivity software. 

What’s more, it can’t be mixed with non-DisplayLink USB adapters. The dock doesn’t support HDCP, will not playback encrypted or copy-protected content. Finally, it wont charge your laptop.
