The Hall Research ULTRA-4K is a dual head HDMI and USB 2.0 KVM range extender kit over CAT6 that includes both a sender and a receiver. The Sender has 3 RJ45 output ports so more than one remote Receiver can be connected. Each Receiver also includes an RJ45 loop-out port for connection of additional Receivers. When more than one Receiver is used in a system, all Receivers show both video screens and keyboard and mouse function is automatically routed to the PC based on activity (virtual USB hub).

The receiver provides two video outputs, dedicated keyboard and mouse USB 1.1 ports (with auto switching), and a USB 2.0 4-port hub for connection of other USB devices such as touch-screens, printers, bardcode readers, etc. Plug-and-Play operation requires no setup whatsoever, just plug the Sender to the receiver using a Cat5e/6 cable and you are ready to go!

The system supports video resolutions to 3840x2160 (UHD/4K), but it also supports and is ideal for applications requiring 2560x1600, 2560x1440, and 1920x1080 resolutions. Other standard HDTV and PC resolutions are also supported.

The RJ45 outputs are also compatible with Single-Head video receiver (Model ULTRA-V-R). The ULTRA-V-R by default will display Video A, but it can be user configured to display video B if desired.


  • Supports high resolution HDMI video including FHD (1920x1080), WQHD (2560x1440), and 4K UHD (3840x2160)
  • Two video heads and one USB port extended over a single CAT5e/CAT6 cable up to 100m/328ft
  • Full plug-and-play support with USB keyboard, mouse, and connected peripherals
  • Computer OS independent - No driver or software required
