Overview

This 4K HDMI extender uses HDBaseT to transmit your HDMI A/V signal to a remote location up to 70 m (230 ft.) away.

Easy and Discreet Installation

The transmitter in this HDMI HDBaseT extender kit features a small footprint and built-in HDMI cable that connects directly to your source for reduced clutter. It’s powered from a USB port on your source device, which makes it easier to install in areas where power outlets may be limited. Mounting hardware is included for the receiver for a discreet, professional installation.

Get 4K Video at 70 m

This HDMI over CAT6 extender maintains your UHD 4K picture quality, even at 230 feet away from your video source. Because the extender is backward compatible with 1080p and lower resolutions at 70 m away, you can comfortably use this extender to make any video source look great. The extender also supports 7.1 audio to ensure all audio channels are captured.

Seamless Integration with Your Existing Infrastructure

The kit extends HDMI over a single cable, unlike some HDMI extenders that require two cables, reducing potential failure points and lowering your cabling costs. Ideal for digital signage, the HDMI over CAT6 extender uses standard CAT5e, CAT6 or CAT7 cables to extend HDMI video over the Ethernet infrastructure that's already in your building.

The ST121HDBTDK is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Applications

Transmit an HDBaseT signal to a boardroom or classroom projector

Distribute digital signage in large buildings like shopping centers, stadiums, schools, and hospitals

Power your transmitter using the USB port on your video source

Frequently Asked Questions

Before You Buy

If you need to use a video extender with a video adapter or converter, you should position the adapter or converter as close to the video source as possible. For example, if you need to take a VGA signal from a computer and send it 200 feet to an HDMI® projector, you should convert the signal from VGA to HDMI and use an HDMI extender.

Note: For more information on when to use cables or extenders, see the following FAQ: http://www.startech.com/faq/video_signal_converters_when_to_convert.

Yes, this video extender works with set-top boxes, provided the set-top box meets the following requirements:

  • The set-top box must be High-bandwidth Digital Content Protection (HDCP) compliant.
  • The set-top box must support devices being connected between the video source and display. If the set-top box requires a direct cable connection between the video source and display, it won't work with this video extender.

No, this device is designed to be a point-to-point solution using networking cabling only. 

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.

HDCP

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.
