Samsung LNB640 series Quick Take

CNET did not review these LCD HDTVs, but we did review a similar model.

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.
