This HDMI over IP extender kit distributes video to a remote location, over your local area network (LAN) and Cat5e or Cat6 Ethernet cabling. By combining this kit with additional receivers (sold separately) and an Ethernet switch (sold separately) you can distribute an HDMI source to multiple locations and create video walls using several remote displays and receivers in the same location. 

You can also use multiple transmitters on the same network to distribute different video sources or connect the transmitter directly to a receiver at up to 330 ft. (100 m), in a point-to-point setup. Remote control of serial devices is supported through RS-232 extension.  

Resolutions up to 1080p, with Audio 

With support for video resolutions up to 1080p (1920 x 1080 at 60Hz), the transmitter also supports digital and analog audio to the receiver and analog audio from the receiver to the transmitter. 

Mobile Control Through a Free App 

The kit includes an easy-to-use online app to manage your IP video distribution.  

The app is available on iOS for an iPhone or iPad, Android for a smartphone or tablet, and Google Chrome browser for a desktop. 

Download the StarTech.com Video Control software to manage your IP video distribution.

NOTE: Your router must support IGMP snooping.  Please refer to your network switch or router documentation to ensure IGMP snooping is supported and enabled.

Hassle-Free Installations 

The HDMI transmitter/receiver kit includes optional shelf-mounting hardware. It uses Cat5e or Cat6 cables and works with existing network infrastructures, eliminating the expense of running proprietary cables. 

ST12MHDLAN2K is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Frequently Asked Questions


If you wish to use multiple transmitters on a network, each Transmitter will need to be set to a different dip rotary switch value (0-9, A-F). Each Receiver will then need to match the transmitter it will be associated with. Note: changes to the dip rotary switches take effect after the transmitter(s) and receiver(s) are power-cycled.


  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.
