Sonnettech Thunderbolt Dual 4K 60Hz DisplayPort Adapter, Silver (for Windows, Intel & M1 Pro/Max Macs; not compatible with M1 Macs)

Connect Two 4K Displays or One 5K Display from a
Single Thunderbolt Port
Sonnet’s Thunderbolt Dual DisplayPort Adapter is certified for use with Thunderbolt 3 Intel Macs, M1 Max, M1 Pro, and M1 Ultra (but not M1) Macs, and Windows® Thunderbolt 3 or Thunderbolt 4 computers; and enables you to connect one or two larger displays to a single Thunderbolt port on your computer. With the adapter connected, you can connect up to two 4K @ 60Hz DisplayPort (DP) monitors, or one 5K @ 60Hz DP monitor.

Adapts to Your Needs
Although the Sonnet adapter supports one monitor with a 5120 x 2880 (5K) resolution, or two monitors at resolutions up to 4096 x 2160 (4K), you can also use it to connect monitors with lower resolution, like full HD 1080p (1920x1080) or 1920x1200 monitors. 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.
