The Smart-AVI 4-Port, Dual-Head HDMI KVM Switch enables you to control up to four systems from a single workstation that consists of two HDMI-enabled monitors, one keyboard, and one mouse. The KVM switch has an integrated 2-port USB 2.0 hub, allowing you to share scanners and printers across connected systems. The switch connects to Windows, Mac, and Linux systems featuring HDMI, USB, and 3.5mm ports, using a set of optional cables. Once connected, it can deliver resolutions of up to 3840 x 2160. Switching between the four host systems can be easily accomplished via physical buttons, hot-key commands, and RS-232 signals. In addition, the switch features keyboard/mouse emulation and EDID pass-through technology for smooth switching capabilities.
