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 130 ft.

(40 m) This HDMI over CAT6 extender maintains your UHD 4K picture quality, even at 130 feet away from your video source. Because the extender is backward compatible with 1080p and lower resolutions at 230 feet 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. More from the

The StarTech ST121HDBTDK is an HDBaseT HDMI extender kit for sending video and 7.1-channel audio over a single Cat5e-or-better cable, making it suitable for classrooms, meeting rooms, and digital-signage installations that need a display up to 230 ft. away; it supports 4K up to 130 ft. and 1080p up to 230 ft.

Recommended For

  • Meeting-room and classroom AV installers who need to connect an HDMI source to a projector across a dedicated Cat5e-or-better cable run, rather than routing a long HDMI cable.
  • Facilities teams setting up fixed digital-signage displays across a building where a direct Cat5e, Cat6, or Cat7 cable can connect the source to a remote screen.
  • AV installers who want a small transmitter at the source end: its built-in HDMI cable connects directly to the source, and USB power can help where a nearby outlet is limited.
  • Users extending a 1080p source to a remote TV, monitor, or projector over a dedicated cable run of up to 230 ft., or a 4K source over a shorter run of up to 130 ft.

Real-World Use Scenarios

  • In a boardroom, connect a laptop or room computer near the table and carry its presentation to a distant projector over a single Cat cable; 4K is supported on runs up to 130 ft., while longer runs up to 230 ft. are suited to 1080p.
  • In a classroom, send video from a computer at the lectern to a projector across the room using installed Cat5e or better cabling, avoiding the need to route a long HDMI cable.
  • For digital signage, place the HDMI source near its equipment and send its content to a display elsewhere in the building; the compact, USB-powered transmitter helps keep the source end less cluttered.
  • When a TV or monitor is mounted away from the equipment, use a Cat cable run between the source-side transmitter and the display-side receiver to deliver HDMI video without extending HDMI directly across the room.
  • For a Blu-ray player or computer connected to a remote HDMI display, extend the video and supported 7.1-channel audio over one Cat cable; the display end still needs the included receiver and power adapter.
