With audio support, you can also connect speakers or headsets. The switch occupies only a single 1U space in a 19" rack and supports screen resolutions of up to 4K Ultra HD 60Hz, great for graphical content in gaming setups, video editing or controlling multiple workstations. It provides 3 switching modes, via keyboard hotkeys, front panel buttons and RS-232 commands. A local console can be connected to the 2 USB and HDMI ports on the rear panel while the built-in 2 port USB 2.0 hub saves money on requiring additional devices by sharing peripherals between the connected computers.
