The ULTRA-4K is a high-performance KVM extender system engineered for environments that demand uncompromising video clarity, secure PC access, and flexible deployment. Using a single CAT6 cable, it extends dual HDMI video signals and USB 2.0 up to 100 meters, enabling users to operate a host computer from one or more remote locations with zero latency or loss in quality. At the heart of the system is the ULTRA-4K Sender, which connects directly to the host PC via dual HDMI and USB ports, while also offering local HDMI loop-through and USB access for on-site control. The Sender features multiple RJ45 outputs, allowing it to support multiple Receivers simultaneously—each displaying the same video outputs and receiving full keyboard/mouse functionality with automatic control switching based on active use.

 

At the remote location, the ULTRA-4K Receiver delivers a seamless user experience, reproducing both video streams in stunning resolution and offering USB connectivity for essential peripherals such as keyboards, mice, touchscreens, printers, and more. Its dedicated USB ports ensure reliable control input, while the built-in USB hub expands operational versatility. The system also includes loop-through RJ45 ports for daisy-chaining additional receivers, making it easy to scale as needed. Designed for plug-and-play simplicity, ULTRA-4K requires no configuration or software—just connect and go. Whether used in a hospital for patient monitoring, in a financial institution for secure trading access, or in any application where reliability and resolution matter, ULTRA-4K delivers powerful, flexible remote computing without compromise.
