StarTech ID: ST122VGA

The ST122VGA 2-Port VGA Auto Switcher lets you share a display between two computers and automatically
switch to the active source device using configurable priority switching. When the port you have selected as the
primary input is turned off, the device automatically switches to the secondary input.

For maximum control and versatility, the ST122VGA also offers manual switch control with an easy-to-use button that
allows you to toggle between video sources.

For a convenient setup the switcher can be powered using the included power adapter or the USB power cable, and
features built-in EDID emulation ensuring maximum compatibility with your display or projector and support for
resolutions up to 1920x1200/1080p.
