IHSE’s new dual-head 4K DisplayPort Extender package increases computer viewing area by more than 50%. The launch of the new Series 490 Draco ultra DP 1.2 Dual-Head system supports up to two 4K60 displays in one extender TX/RX set. Packaged in a compact enclosure are two DisplayPort KVM fiber-optic main boards and an internal power supply that creates a unique extender solution­­ for business and professional users focused on ultra-high-resolution imaging such as command and control, air traffic control, visual medicine, and geospatial mapping.


With the Series 490 dual-head extender units, users can support either a stretched desktop of up to 8192 x 2160 (2 x 4096 x 2160) across two displays or run them in “clone” mode to show the same 4K content on both displays; depending on the computer’s graphic card capabilities. Duplicating the desktop display in clone mode is useful for presentations in which the presenter works from one monitor while the audience views the presenter’s work on a large screen or projection system. Operating in full 4K stretched desktop mode allows full-4K graphic applications across both displays to provide increased workspace for application tools.


The Draco ultra DP base board is the first 4K DisplayPort KVM extender with a 60-hertz refresh rate in full 30 bit color depth and 4:4:4 sampling. The extender boards use the innovative Lightweight Image (Lici®) codec, developed in cooperation with the Fraunhofer Institute for Integrated Circuits. This revolutionary coding technology ensures brilliant image quality at the highest video resolutions with outstanding color accuracy (deep color-ready).


The Draco ultra DP Dual-Head extender package allows users to operate CPUs from a remotely located workstation over two duplex fiber cables. Each extender transfers digital video in 4K resolutions up to 4096 x 2160 and 3840 x 2160 at a 60-hertz refresh rate and full color depth (30 bit, 4:4:4).


These extenders can also support audio transmission via the DisplayPort interface, eliminating the need for additional audio modules and enabling playback of the audio signal on monitors with integrated loudspeakers. It is also possible to integrate optional Draco vario mezzanine modules for digital audio input and output and for data signals such as USB 2.0 and RS-232 / RS-422 when upgraded to a larger enclosure.


In addition to extending point-to-point high-resolution images as far as 5 kilometers (3.1 miles), the DP 1.2 Dual-Head can be integrated into IHSE’s XV models of KVM matrix switches, allowing users to share 4K sources across multiple workstations.


Features and Benefits

Maximize productivity with dual 4K video

With support to configure two DisplayPort video inputs and a CPU with dual DP 1.2 outputs, these units help maximize productivity by providing the freedom to multitask more within the same viewing area of a traditional dual-head 1080p displays.


Get more viewing area in the same workspace.

When set to a stretched desktop option, the Dual DP 1.2 package makes it ideal for creating a high resolution workstation where high quality imaging is critical – such as graphics design or aerial mapping.


Use a single keyboard and mouse

The dual-head 4K DisplayPort, offers a built-in USB-HID port configuration that allows your keyboard and mouse to pan across both displays saving time and work space.


Supports all current DisplayPort 1.2 resolutions

With this dual-head 4K DP extender package, IHSE brings the next level of dual-screen capabilities to users looking to increase their productivity with large UHD dual-display workstations for ultra-high-resolution imaging, mapping, or multi-application setups.




Integration of Fraunhofer IIS’s lightweight coding technology into next-generation KVM extenders


Lici® (Lightweight Image Coding technology)

  • Mezzanine compression up to mathematically lossless
  • RGB/YCbCr or raw data compression
  • Up to 32 bit color depth
  • 2K/4K/8K possible
  • No frame drops
  • Low latency


The Draco ultra DP is the first ever KVM extender that uses Lici®, Fraunhofer IIS‘ Lightweight Image Coding technology. Lici® ensures brilliant image quality at the highest video resolutions with outstanding color accuracy.



The Draco ultra DP extenders are offered in single or redundant path variants. Redundant data links increase system resilience, prevent system failures and can also be used for duplicating signals.
