The UDA2000 is a new USB 2 to HDMI display adapter from Cirago International that allows both Mac and Windows users to easily connect to HDMI monitors, projectors or HDTVs without having to add internal video cards, external breakout expanders or separate audio and video connections in order to increase the number of monitors they can work with. PCs can add up to six 1080p-compatible monitors, while Mac users can add up to four, each using a USB port and adapter.
