This HDMI® over CAT6 extender lets you extend two HDMI sources up to 90 m (295 ft.), to individual HDMI displays over a single  CAT6 cable. Designed for a simple, tidy setup, the extender also supports bi-directional IR control for added flexibility.

Dual source support

Reduce the need for additional equipment and cables, by extending two HDMI connections with a single CAT6 cable. Running only one cable can save cost on installation or enable you to extend two HDMI signals using an existing cable run. You can also use this 1080p HDMI extender to run separate video signals to the same display, for mission critical digital signage applications where if one signal goes down, the other can easily be swapped in it's place.

Bi-directional control

With bi-directional IR control, you can control your devices from either end of the extension, such as a Blu-ray™ player and laptop on one end and two TV displays on the other. The extender includes an IR kit with discreet dongles that easily connect to both your transmitter and receiver, enabling you to remotely control any device you choose from either side of your extension.

Simplified setup

The simplicity of one-cable setup avoids the hassle of running multiple cables, while also reducing potential failure points. The included mounting hardware offers professional mounting options ideal for public spaces such as offices or auditoriums.

The TAA compliant ST222HDBT is backed by a 2-year StarTech.com warranty and free lifetime technical support.


  • Great for tradeshows where multiple remote source devices need to be placed out of sight
  • Ideal for auditoriums, lecture halls or other professional presentation venues, where a discreet setup is required

Frequently Asked Questions


  1. The power adapter may not be connected at the correct unit or may not be connected at all.  Please check your product manual to see where your power adapter has to be positioned.
  2. An adapter to another video signal may be connected to the Transmitter or Receiver unit.  Please avoid any converters for the initial setup.
  3. The Cat 5 or 6 cable coming from the transmitter or receiver unit may be connected to a network switch.  Some of our video extenders will work in this configuration, but others will not. Please check your product manual to see if your model can be used connected to an IP network. For the initial setup, avoid connecting the Cat 5 or 6 cables to any network switch, hub, or router.
  4. The category of Unshielded Twisted Pair (UTP) cables may not meet StarTech.com’s requirements. Ensure at least Cat 5, 5e, or six cables are used, and they have eight wires. Some Cat 5 cables only have four wires. If using Cat 6 cables, be aware they have more twists per foot, so you may have to use shorter cable lengths if using Cat 6 cabling between your video extenders.
  5. Bundling up the UTP cabling connected to the extenders can cause crosstalk, which will prevent the video signal from showing on the display.  Unwrapping the cable should resolve this issue.
  1. Please check to see if your model has an adjustable Gain dial on the remote unit.
  2. If it does, use it to adjust the color until it is acceptable.
  3. Replace the VGA cable with a higher quality cable like StarTech.com’s MXT101MMHQ.
