The 2-Port DVI Video Splitter from Aluratek can be used to send an identical DVI-D signal to two separate monitors. Plug and Play and Hot Swapping support make setup simple. The DVI-D signal supports HD resolutions up to 1900 x 1200 or 1920 x 1080 widescreen, and the splitter is daisy chainable so you can send the signal to even more monitors.
