Value Comparison Summary


The Samsung LN50B650 is a significantly better HDTV than the Toshiba Regza 40XV645U, offering better color reproduction, motion performance and even slightly better contrast ratio, something the Toshiba excels at. It also brings internet connectivity and better media playback features to the table. You'll pay for these upgrades, however, with the Samsung model retailing for $800 more than the 40XV645U. Even with that price difference, however, we lean towards the Samsung LN40B650 as the better value if you care about the internet connectivity and media playback features.
