StarTech.com 2 Port VGA Auto Switch

The ST122VGAU VGA Auto Switcher lets you share a display between two computers and prioritize your VGA signals. The VGA switch features a primary and secondary VGA input port, and automatically outputs the signal from the primary input. When the signal feed connected to the primary input port is cut, the switcher automatically defaults to the video signal on the secondary VGA input port. Designed for maximum control and versatility, the VGA Auto switcher also offers manual control of connected signals with easy-to-use front panel buttons that allow you to toggle between video sources.
