The SIIG 2x2 VGA & Audio Matrix Switch lets you connect two VGA sources and output either of them onto one or two VGA displays at the same time. And you can switch between the two input sources by means of front panel buttons.
The switcher supports resolutions up to 1920 x 1440, supports VGA, SVGA, XGA, UXGA, and multi-sync monitors, and outputs analog stereo audio by means of 3.5mm jacks. Video bandwidth can be up to 200 MHz. The housing is metal and ensures durability and reliability.
For audio support, SIIG's VGA cable with audio can be used.
