Dual 4K Adapter for Thunderbolt and USB

The Sonnet DisplayLink adapter connects two 4K displays at 60 Hz or two 1440p or 1880p displays at 144 Hz to a single Thunderbolt or USB 3 or 4 port on a Mac or Windows computer. A USB-A female to USB-C male adapter is included for port flexibility. Audio pass-through is supported across the connected displays.

Suits Mac and Windows users needing two extra

It suits professionals expanding a laptop workspace with dual high-resolution monitors and supports Apple Silicon M1, M1 Pro, M1 Max, M1 Ultra and M2 MacBooks alongside Windows systems. Users whose computers lack Thunderbolt or USB 3 or 4 ports cannot use this adapter. Buyers needing more than two external displays should look at a different solution.

Two 4K 60 Hz outputs from one port

The decisive specification is the ability to drive two 3840 x 2160 displays at 60 Hz from a single Thunderbolt or USB 3 or 4 connection. If your workflow requires only one additional screen, a simpler single-output adapter may suffice.

Questions about this item

Do I need a free Thunderbolt or USB 3 or 4 port on my computer to use this adapter?

Will my existing 1440p 144Hz monitors work with this adapter?

The adapter supports two 1440p or 1880p displays at 144Hz via its HDMI outputs, so your current monitors will work at their native refresh rate.

How can I confirm both screens are running at 4K 60Hz after I plug them in?

Check your operating system display settings; each connected display should show 3840x2160 resolution at 60Hz to confirm correct operation.
