Note that the restriction on external monitors can be worked around by using a DisplayLink compatible dongle/dock, since it uses a custom driver (I assume it does something in software that would otherwise be limited in hardware).

I use the Dell D6000 and I run three (1080p) external monitors in addition to the built in monitor.

I've been trying to find a DisplayLink dock that can output video via USB-C or Thunderbolt. Everybody's shared solutions always involve HDMI connections, never USB-C.

I have two Thunderbolt/USB-C monitors that I was hoping to daisy chain with one wire from my Mac. Alas it's not possible.

My hope is power into a dock. Thunderbolt from dock to laptop to power laptop. Thunderbolt/USB-C from dock into first monitor. Second Thunderbolt/USB-C from dock using the DisplayLink tech to second monitor.

You won’t find a Displaylink adapter that supports Thunderbolt monitors. It just won’t work from a technical aspect.

Three 1080p displays add up to 3/4 the bandwidth of one 4k display, at the same framerate.
