The Aten CS1794 KVM switch connects up to 4 computers via HDMI and lets you control them from a single USB console. The built-in USB 2.0 hub lets you share two additional USB devices, while you can switch between computers using the front-panel buttons or keyboard shortcuts.

Video DynaSync technology stores the console monitor’s EDID information to optimize HDMI resolution. The device supports digital audio, including Dolby True HD and DTS HD Master Audio, as well as Auto Scan mode to monitor connected computers and HDMI devices. When a computer is turned off, the switch automatically moves to the next available one.
