This new KVM Switch lets you control up to four dual-head, VGA-enabled USB computers from one USB console that includes two VGA monitors. Used with coaxial VGA cabling, the Switch supports video resolutions of up to 2048x1536@85Hz through a 400MHz video bandwidth, delivering the highest resolution possible without compromising display quality. The ideal solution for multi-display users requiring access to up to four computers, it eliminates the clutter and expense of additional keyboards, mice, and monitors. This innovative design provides built-in cable management to save space on your desktop. Offering such advanced features as audio and microphone support, the SOHO Series with Audio enables you to switch between computers without having to unplug and re-plug speakers and microphones. To ensure compatibility with the latest computers and devices, a flash-upgrade feature lets you update firmware when necessary.
