The TAA compliant Dual-Monitor DVI KVM Switch controls four multimedia computer systems from one dual-DVI monitor workstation. The KVM switch supports four separate multimedia computer systems & the use of a dual DVI-D single-link monitor workstation, increasing productivity by enabling you to access more information at once. The 2-port hub that's built into the USB (Universal Serial Bus) 3.0 KVM switch shares two additional peripherals (in addition to keyboard & mouse) among attached computers as if they were directly connected while supporting high-performance peripherals such as flash drives & video capture devices. With support for separate stereo audio & microphones, the KVM switch box connects everything you need directly to your systems, saving you money & desk space. The front-panel push-buttons make it easy to switch between systems & activate the auto-scan feature. The hotkey functionality makes accessing each system quickly, while an optional buzzer sound confirms the switch. Star Tech.com offers a wide selection of high-quality KVM switches & KVM-related products to help you access your systems more efficiently without the expense & clutter of extra keyboards, mice, & monitors.
