Samsung today held a rare single-model introduction and added a new model to its 650 series TVs at the CEDIA expo. At 65 inches across, the LN65B650 is one of the largest ever conventionally-lit LCDs from the company and sits in the middle of the lineup in features, with Internet support for Flickr, Yahoo and YouTube as well as a 120Hz panel, a 4ms pixel response time and a 100,000:1 dynamic contrast ratio.
