CNET did not review the Sony KDL-EX400 series of LCD TVs, which includes the 46-inch KDL-46EX500, the 40-inch KDL-40EX400, and the 32-inch KDL-32EX400, but we did review the KDL-EX500 series, which is similar.
The major difference between the two series is the inclusion of a 120Hz refresh rate and Sony MotionFlow dejudder processing on the EX500 (more info). The EX500 also has a slightly better dynamic contrast ratio specification. Aside from these differences, we expect the picture quality of the KDL-EX500 to provide a very good indication of how the KDL-EX400 will perform.
