The Atlona AT-HD550 is a HDMI converter and scaler that's designed to allow a user to match the native resolution of a different display when multiple are used. The HD550 is mainly designed to be used with standard displays, HDMI Matrix switches, HDMI distribution amplifiers, and many other applications where HDMI is used.
