The Cubi Q CS1764A USB (Universal Serial Bus) 2.0 DVI KVMP switch charts a revolutionary direction in KVM (Keyboard, Video, Mouse) switch functionality by combining a 4 port KVM switch with a 2 port USB (Universal Serial Bus) 2.0 hub at the same time as it provides an interface for a digital monitor (DVI). In addition, the CS1764A comes with ATEN's Video Dyna Sync technology, which optimizes display resolution, & power on detection, which means if one computer is powered off, the CS1764A will automatically switch to the next powered-on computer. As a KVM switch, it allows users to access four computers from a single USB (Universal Serial Bus) keyboard, USB (Universal Serial Bus) mouse, & monitor console. As a USB (Universal Serial Bus) 2.0 hub, it permits each computer to access any peripherals connected to the hub on a 'one computer at a time' basis. Please note: networking components such as switches, routers, KVM & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
