The VS461 4-Port DVI Video Switch from ATEN combines a single link DVI switch with stereo audio, allowing you to switch between the digital video and audio outputs of multiple digital devices through a single DVI display and set of speakers. Toggle between the DVI input sources using the pushbuttons displayed on the switch's front panel, or by using the included IR remote control. It provides a video quality up to 1920 x 1200, supporting digital and analog video input for flat panel displays, data projectors, plasma displays, digital TVs, and set-top boxes, as well as traditional monitors and TVs. The power-on detection automatically switches to the next powered-on source whenever a DVI source is powered off. The ATEN switch supports both PC and Mac operating systems, and comes in a metal housing that features a stackable design for improving workspace organization.
