Where to buy

This HDBaseT HDMI Matrix Switch and Cat5 extender is an all-in-one digital signage solution that enables you to extend four distinct HDMI audio/video sources up to 230ft (70m), to four remote displays using STHDBTRX receiver units (sold separately). Matrix switching allows each of the remote displays to output and switch between any of the video sources.

What is HDBaseT?

HDBaseT is a standardized, zero latency, video distribution technology that’s revolutionizing HDMI distribution. HDBaseT uses an advanced method of modulation that enables you to distribute uncompressed HDMI audio and video along with additional signals such as 100BaseT Ethernet, IR, RS-232 serial and power over cable.

Simplify your setup

The switch extends HDMI using standard Cat5e or Cat6 Ethernet cable with RJ45 connectors, allowing you to use your existing cabling infrastructure, with no added cost in specialized cabling or connectors.  Plus, because the HDMI extender also allows for matrix switching in one easy-to-use and clutter-free device, it eliminates the expense and hassle of running multiple devices.

Extend more with HDBaseT

For complete end-to-end control the switch can extend Infrared using the IR extender and receiver cables included with the STHDBTRX receiver units (sold separately). For local operation, the HDMI switch also includes a remote control, and easy-to-use front panel buttons that allow you to toggle between video sources.

High-Definition picture quality from an impressive distance

Ideal for High-Definition applications, the matrix switch supports 1920x1200/1080p video resolutions and digital audio. Plus, built-in EDID monitor emulation ensures native resolution and maximum compatibility with your display or projector, for a convenient plug-and-play installation.

The ST424HDBT is backed by a StarTech.com 2-year warranty and free lifetime technical support.


  • Connect 4 different HDMI sources to 4 different displays, in different locations around a large building such as a shopping center, school, or hospital
  • Place the displays in a convenient viewing area, while the HDMI source equipment is placed elsewhere in a separate, secured environment

Frequently Asked Questions


When you troubleshoot issues with a video splitter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Video cables

  • Video switch

  • Video source (such as a DVD player or computer)

  • Video destination (such as a monitor or projector)

Note: When you are testing setup components, you should avoid using video adapters. For example, if you are converting a VGA source to HDMI for use with an HDMI switch, you should use an HDMI source when you test the components.

To test your setup components, try the following:

  • Use the cable, video switch, video source, and video destination in another setup to see if the problem is with the components or the setup.

  • Use a different cable, video switch, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

  • Remove the video switch from your setup and test to make sure that the video source and video destination work together without the video switch.

  • Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, switch, and destination all need to support the resolution that you are using.

Before You Buy

This device outputs HDMI video signals. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.


When you consider whether to convert an HDMI video signal to another connection type, it is important to know if the media that is being converted from the HDMI video connection is protected by High-bandwidth Digital Content Protection (HDCP). If the media is protected by HDCP, you cannot convert to analog video connections because they do not support HDCP. You may experience this issue when you use devices like Blu-ray players, DVD players, and certain gaming consoles.
