The Vista DP switch is ideal for switching up to four DisplayPort/USB computer digital video/USB sources to one monitor and USB keyboard/mouse. Crystal clear video at resolutions up to 3840 x 2160 @30Hz make this unit a perfect addition to any video environment. Switching and selection are made easy using the front panel display, hotkey sequences, or serial switching commands on a remote computer via a serial cable. The KVM, USB peripherals, and audio can all be switched in conjunction to a selected CPU port, or can be switched independently to separate ports. All Vista DP models support USB 1.1/2.0 keyboards, mice, and peripherals, and include stereo audio(speaker) support.
