CNET did not review the Sony KDL-V4100 series from 2008, but we did review a couple of models in related series.
The Sony KDL-V4100 series was introduced in the spring of 2008. It consists of the 40-inch KDL-40V4100, the 46-inch KDL-46V4100, and the 52-inch KDL-52V5100.
CNET did not review any of these models, but we did review a similar product, the Sony KDL-46W4100, that may give you an idea of how the KDL-V4100 will perform. The V4100 has a slightly lower contrast ratio (3,000:1 vs. 2,500:1) than the W4100, so it will probably display lighter black levels. It also lacks 120Hz processing. For more information, refer to the full review of the Sony KDL-46W4100.
For 2009 Sony has released a replacement of this TV, the KDL-V5100 series, that we did review.
