Switching between connected computers is quick and simple using keyboard hotkeys or pushbuttons. An independent audio\/mic and USB peripheral switching function allows for an uninterrupted experience. A computer can be printing on a printer connected to one of the USB 2.0 peripheral ports, while you listen to audio from and access another computer; all at the same time.\n\nThe B004-DUA2-HR-K uses DVI-I technology, allowing for the transmission of a Dual Link digital (up to 2560x1600) or analog (up to 2048 x 1536) signal.
