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.

CNET did not review the Samsung PNC550 series of plasma TVs, which includes the 50-inch PN50C550, the 58-inch PN58C500, and the 63-inch PN63C550, but we did review the PN50C590 series, which is similar.

The major difference between the two series is the inclusion of CinemaSmooth processing on the PNC590 models, which allows proper reproduction of 1080p/24 content (more info). Aside from this difference, we expect the picture quality of the PNC590 to provide a very good indication of how the PNC550 will perform.
