Designed and manufactured in the UK by Scene Double, our analogue KVM extenders allow you to separate your VGA monitor, keyboard and mouse from a CPU over distance as well as being able to extend high-quality audio and serial signals.

Our proprietary technology seamlessly extends VGA video and USB (HID) or PS/2 signals over CATx (copper) cabling to distances up to 300 metres – much further than with ordinary KVM cabling. Trusted by companies worldwide, our extenders have a proven track record in many mission-critical environments, including:


Broadcast • Air Traffic/Airports • Government • Defence • Banking & Finance • Industrial Processes • Medical & Healthcare • Maritime & Offshore • Utilities & Transportation

Suitable for all desktop applications, SD-VUE and SDBX extenders support resolutions up to 1920 x 1200 and supports single or dual-head VGA video. Perfect for environments that require robust KVM extension at minimal cost.
