Samsung LNB640 series Quick Take

The Samsung LNB640 series of LCD HDTVs was introduced in the spring of 2009 and is excluive to electronics retailer Best Buy. It consists of the 32-inch LN32B640, 40-inch LN40B640, 46-inch LN46B640 and 55-inch LN55B640.

CNET did not review any of these models, but we did review a similar product, the Samsung LN46B650, that may give you an idea of how the LNB640 will perform. The LNB640 has a slightly lower contrast ratio (80,000:1 vs. 100,000:1) than the LNB650, so it will probably display somewhat lighter, less realistic black levels. The LB640 has an additional composite input, but it doesn't have networking or Wi-Fi capabilities beyond the company's InfoLink system (check out the review of the UNB466000 for more info). Its styling is also a subtler gray as opposed to the B650's red. For more information, refer to the full review of the Samsung LN46B650.
