Sonnet TB3-DDP4KG USB graphics adapter 4096 x 2160 pixels Black, Grey

Connect Two 4K Displays from a Single Thunderbolt Port
Sonnet’s Thunderbolt Dual DisplayPort Adapter is certified for use with Thunderbolt 3 Intel Macs, M1/M2 Max, M1/M2 Pro, and M1 Ultra (but not M1/M2) Macs, and Windows® Thunderbolt 3 or Thunderbolt 4 computers; and enables you to connect two larger displays to a single Thunderbolt port on your computer. With the adapter connected, you can connect two 4K @60Hz DisplayPort (DP) monitors.

Adapts to Your Needs
Although the Sonnet adapter supports two monitors at resolutions up to 4096x2160 (4K), you can also use it to connect monitors with lower resolution, like 1440p (2560x1440), or full HD 1080p (1920x1080). This makes it great for use for different home and office workspace applications. And, with built-in audio support, there’s no need for you to connect an additional cable to hear sound from the monitors.
