Dual 4K 60 Hz video output

This USB-C adapter drives two external monitors at up to 3840 x 2160 at 60 Hz, adding a 3.5 mm audio jack and a 100 W pass-through charging port. It is aimed at laptop, tablet or phone users who need extended desktop space for productivity work.

Plug-and-play with OS limits

No driver installation is required; simply connect the adapter to a USB-C port that supports video output. On Windows the device can extend across two screens, while on macOS both external displays show the same mirrored image. Smartphones and tablets with video-capable USB-C ports are restricted to mirror mode only.

Bandwidth and host constraints

The adapter relies on the host’s USB-C alternate-mode bandwidth, so dual 4K 60 Hz output is only possible when the source provides sufficient throughput. It also requires the connected power supply to deliver up to 100 W for full pass-through charging; lower-rated chargers will reduce available power.

Questions about this item

How can I verify the adapter is delivering 4K at 60Hz to both connected monitors after setup?

Check each monitor's on-screen display or your operating system's display settings to confirm both screens report 3840x2160 at 60Hz.

Which cables and accessories are included in the box, and what must I provide separately?

A 2 ft 4K HDMI cable is included; you must supply the second HDMI cable, your laptop's USB-C power adapter for the 100W charging port, and any 3.5mm audio cable.

My laptop runs Windows with an Intel CPU and a USB-C port that supports video — which display modes can I expect?

You can use Extend Two Screens, Extend One Screen, or Mirror mode; MacOS and mobile devices are limited to Mirror or single extended screen.
