Although CNET did not review the Sharp LC-60LE831U, which is exclusive to Best Buy, we did review a similar, non-exclusive TV, the LC-60LE830U.
According to the manufacturer the only differences between the two are that Best Buy's LC-60LE831U lacks Quad Pixel Plus and IP Control features, and that the dynamic contrast ratio specification on the 831U is 5,000,000:1, compared with the 830U's 6,000,000:1.
We don't expect the difference in contrast ratio specification to have a major impact on picture quality, but we can't say for sure since we haven't tested the 831. See specifications to ignore from our TV buying guide for details.
