Samsung’s 550 Series is a perfect  way to step up to Full HD 1080presolution. A fast 5 ms response rate produces smooth-motion scenes for sports and action movies, and a dynamic contrast ratio of 30,000:1 makes for deep blacks and crisp lines (15,000:1 in 32-inch and 37-inch models).  Superb connectivity and networking  with a USB port and 3 HDMI 1.3 ports
