Four-system dual-monitor switch

The STARTECH SV431DDVDUA lets one keyboard, one mouse, one VGA monitor and one DVI monitor control four multimedia computers. It is aimed at office or home users who need to operate several systems from a single desk without swapping cables. The unit includes a USB 2.0 hub and 3.5 mm audio ports so peripherals and speakers stay connected while you switch between machines.

Build integration with dock compatibility

Each computer connects through a DVI-I single-link and an HD-15 port plus a USB Type-B link, while the console side provides matching video, USB Type-A and audio jacks for the shared set. A power adapter is supplied so the switch does not draw current from the host ports. The device is confirmed compatible with the HP 2012 series docking station, simplifying deployment in environments that already use that dock.

Sustained multi-system operation

Video signals pass through at up to 1920 x 1200 resolution without software drivers, so switching remains instantaneous during long work sessions. The USB 2.0 hub maintains peripheral connectivity across all four ports, and the audio channels stay active for microphone and speaker use. No fan or active cooling is present, so the unit runs silently while handling continuous quad-system traffic.
