Dual HDMI output for two monitors

The Sabrent DA-UCDH adapter adds two HDMI ports to a single USB-C connection. It drives two displays simultaneously at 3840 x 2160 resolution and 30 Hz refresh. The device is compatible with Windows systems only and is not supported on Mac OS.

Check for DisplayPort Alternate Mode on your USB-C

Before ordering, verify that your computer's USB-C port supports DisplayPort Alternate Mode. Not all USB-C ports provide video output, and the adapter will not function without this capability. Windows enables both SST and MST modes for extended or mirrored desktops.

Upgrades from a single-video-output USB-C port

This adapter replaces the limitation of one built-in video port by splitting the signal to two HDMI monitors. The jump is worth it when you need dual-screen productivity at 4K 30Hz and your laptop or desktop has a compatible USB-C port with Alternate Mode support.

Questions about this item

Does the package include the HDMI cables I need for the two monitors?

Only the adapter and a user manual are included; two HDMI cables must be purchased separately.

Which operating systems let me run two different 4K desktops instead of a mirrored image?

Windows supports MST for independent 3840x2160 30Hz displays; macOS is limited to mirror mode and is not officially supported.

Will I get 3840x2160 at 30Hz on both screens if my laptop USB-C port lacks DisplayPort Alternate Mode?

No — the port must support DisplayPort Alternate Mode, otherwise the adapter cannot output any video signal.
