Suitable for

When it may not be suitable

This hub provides HDMI output at up to 3840 x 2160 at 30 Hz, which may not meet needs for 60 Hz 4K displays or high-refresh-rate monitors. It is not a replacement for docking stations that require integrated charging at higher wattages or multiple dedicated display outputs for multi-monitor setups.

Key specifications

How to use

Connect the hub to a host computer using the integrated USB-C cable or connector. Plug USB-A peripherals into the Type-A ports, and use the USB-C port for connecting a device that supports Power Delivery if you need to charge the host or supply power. Insert an Ethernet cable into the RJ-45 port for wired network access and connect an external monitor or TV to the HDMI port to enable video output. The host operating system should detect connected devices automatically; install drivers if prompted by the OS.

What to consider before purchase

Recommendations

Use the IUH3RJ4K to restore missing ports on ultraportable laptops: connect peripherals and a wired network when working from fixed desks, and attach a single external 4K display for presentations or extended desktop use. For continuous high-power charging or multiple high-resolution displays, consider a higher-capacity docking solution.
