Dual HDMI 4K 60Hz Output

This USB-C adapter connects one host to two external monitors at up to 3840x2160 at 60Hz. It adds a 3.5mm audio jack and a 100W Power Delivery pass-through port so the laptop charges while video plays. Windows systems support both mirror and extended desktop modes. No extra power supply is needed.

Windows Users Seeking Two Screens

The hub suits professionals who want dual 4K displays from a single USB-C or Thunderbolt 3 port on a laptop, tablet or phone. Mac owners should note that macOS only mirrors the same image to both screens and cannot extend them. Devices without DisplayPort Alt Mode on their USB-C port will not work with this adapter.

Resolution Range and Power Headroom

Supported resolutions run from 640x480 at 60Hz up to 3840x2160 at 60Hz across both HDMI outputs. The 100W PD input handles charging for most ultraportables and mainstream laptops when used with the original charger. Very high-power workstations that draw more than 100W will not charge at full speed through this hub.

Questions about this item

What laptop port do I need to connect this adapter?

A USB-C port that supports video output (DisplayPort Alt Mode) or Thunderbolt 3 is required; plain USB-C charging-only ports will not work.

Will both monitors show different desktops on macOS?

No, macOS only supports mirror mode across the two HDMI outputs so both screens show the same image; Windows can extend or mirror.

How do I confirm 4K 60 Hz output on each display?

Check each monitor's on-screen menu — it should report 3840 x 2160 at 60 Hz; Windows Display Settings or macOS System Report will also list that resolution and refresh rate.
