Multiport USB-C adapter with 8K HDMI

This compact adapter converts a USB-C or Thunderbolt 3 port into a full workstation with HDMI video output, three USB ports and Gigabit Ethernet. It transmits digital audio and video up to 7680 x 4320 resolution while delivering up to 100 W of power delivery to the host device. HDR and HDCP 2.3 support are included for protected high-dynamic-range content. The unit operates without driver installation on supported hosts.

Who this suits and who should look elsewhere

It suits users who need a single 8K display, wired network and extra USB-A ports from one USB-C connection while charging their laptop. Buyers who require multiple external monitors, USB-C downstream ports, SD card slots or audio jacks will not find those features here. The adapter supports only one display at a time, so multi-monitor setups need a different solution.

Deciding specification: 8K HDMI at 7680 x 4320

The HDMI port outputs 8K at 7680 x 4320, plus 5K at 5120 x 2880, 4K at 3840 x 2160 and Full HD at 1920 x 1080. This maximum resolution is the key figure that determines whether the adapter matches your display and host capabilities. Verify that your USB-C port supports DisplayPort Alternate Mode and that your monitor accepts the desired resolution over HDMI.

Will my existing HDMI monitor limited to 4K resolution work with this 8K-capable dock?

Yes, the HDMI output supports 3840 x 2160, 1920 x 1080 and other lower resolutions alongside the maximum 7680 x 4320 mode.

How can I confirm the dock is delivering the full 8K 7680 x 4320 signal to my display?

Check the display’s on-screen information or OS display settings to verify the active resolution reads 7680 x 4320 and that HDR is active.
