Full HD 1080p resolution and Samsung Cinema Smooth technology deliver a wide range of brilliant colors, with bright images and crisp definition. The blackest blacks, brightest whites and nuanced tones are yours with a 10000:1 dynamic-contrast ratio. Hidden speakers deliver clear, robust SRS TruSurround XT sound. The 120Hz switching speed and Game Mode keep gamers marveling at the lifelike action.

Please note: Samsung recently changed the suffix on this TV from HLT-5687X-XAA to HLT-5687SAX. The change was not technical in nature and there is no difference other than the suffix in the model number.

The DLP chip is faster than any other HDTV technology, with the mirrors switching on & off 15,000 times a second to deliver a razor-sharp picture for fast moving images. When combined with Samsung’s new Cinema Smooth light engine, the result is a crisp, bright picture with deep, rich colors that’s closer to film.

I patiently did the Homework. The Comments were and are the best idea for consumers who want the peace of mind they made the Best Choice . Customer comments, such as "buy the Next size up", because the stations transmit smaller images than the screen size YOU purchased,
ex: 56" screen displays a 46" in the 4:3 transmission on cable networks.
Amazon was a Good first time experience. Research/ Buying/Delivery and Product is just what you should expect. I purchased the Samsung Surrond to compliment the Large Screen, and if you want to save more time and money, purchase the Optical and HDMI Cables OnLine as well, the Local dealers Are more expensive , including the delivery charge (if there is one online from Amazon). Consumer Reports substantiated my homework as well in recent issues. Thank You Amazon & Samsung .
