The Startech P2ADD121D-KVM-SWITCH is a high performance KVM switch with built-in video matrix, allowing you to control two DisplayPort enabled computers from a single console. The video matrix function allows you to view one display from each connected computer and switch the keyboard, mouse and audio device between the selected displays using hotkeys. You can also switch all connected peripherals and both monitors like a standard KVM. The KVM also features a built-in USB audio device, which provides 3.5mm audio jacks for both microphone and speakers, integrating audio management directly into the switch.
