Compact silver hub with three USB-A ports and one HDMI port on a short USB-C tether

LORDWORLD

LORDWORLD USB 3.1 Type-C to 3× USB 3.0 Hub with 4K HDMI (JCH451)

SKU CH-C6H9-6R5QC

Adds three USB 3.0 Type-A ports and a 4K HDMI output at 3840 x 2160 @ 30 Hz to a USB-C device with DisplayPort alt mode

  • Add three USB 3.0 ports for peripherals with 3.1 / 3.0 / 2.0 backward compatibility
  • Connect a 4K display at 3840 x 2160 resolution running at 30 Hz
  • Works instantly with plug-and-play — no drivers or software to install
  • Expands a single USB-C port into three USB-A ports plus HDMI video output
  • Requires host USB-C port with DisplayPort alt mode for full HDMI functionality

3× USB 3.0 ports plus 4K HDMI

This hub adds three USB Type-A 3.0 SuperSpeed ports and one HDMI output to a single USB 3.1 Type-C connection. It is designed for laptop or desktop users who need extra peripherals and an external display without installing drivers. The unit is plug-and-play and works with USB 2.0 devices as well.

HDMI limited to 30 Hz at 4K

The HDMI port supports a maximum resolution of 3840 x 2160 at 30 Hz, so high-refresh-rate monitors will run at a lower frame rate. USB 3.0 data throughput is shared across the three ports and the host link. Full video function requires the host USB-C port to support DisplayPort alt mode.

Host port must support DisplayPort alt mode

If the computer's USB-C port lacks DisplayPort alt mode, the HDMI output will not work even though the USB ports remain active. Buyers who need video on a host without alt mode cannot use this adapter for that purpose.

Questions about this item

Should I pick the JCH451 or a different version of this hub?

The JCH451 is the single model offered; it provides three USB 3.0 Type-A ports plus one HDMI output.

What does the 3840 x 2160 @ 30 Hz figure mean when I plug in a monitor?

It is the maximum resolution and refresh rate the HDMI port can drive, so a 4K display will run at 30 Hz.

Which USB standard does the Type-C connector use and what speed does it cap at?

The hub connects via USB 3.1 Type-C and the three Type-A ports run at USB 3.0 SuperSpeed (5 Gbps).
