Multi-Input HDBaseT Extender Kit with Built-In
Switch and Video Scaler
Product ID: ST121HDBTSC
This multi-input HDBaseT™ extender kit extends your A/V signals to a remote location up to 230 ft. (70
m) away. It features a built-in switch and scaler, so you can choose which video source is output from
four independent video sources (2 x HDMI, 1 x VGA and 1 x DisplayPort).
Seamless Integration and Operation
The HDBaseT extender’s built-in converter switch lets you connect two HDMI sources, a VGA source, and
a DP source to the same remote and local HDMI display. You don’t need adapters or scalers, or a video
switch.
Along with manually switching your video source with easy-to-use buttons, the video extender ensures
hassle-free operation with two auto-switching modes: auto-detect switching, which detects and selects a
newly connected device, and priority selection, which lets you choose which port is activated by default,
for automatic switching.

Built-In Video Scaling
This HDBaseT extender features a built-in scaler that scales the image to 1080p, so you can rest assured
your HDMI display will intuitively work with any source that’s connected through it. Scaling is easy to
do, with an intuitive OSD that's accessible using buttons on the remote receiver. Newer HDMI displays no
longer support legacy resolution video signals. Without support for these common VGA resolutions, your
source may not work with your new HDMI display.
High-Definition 1080p Video at 230 Feet (70 Meters)
The extender kit maintains your HD picture quality, even at 230 ft. (70 m) away from your video source,
ensuring you can provide the best possible viewing experience.
The ST121HDBTSC is backed by a 2-year StarTech.com warranty and free lifetime technical support.
