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.

Motion
Both televisions sport 120Hz refresh rate, and both have some significant problems. The Samsung LN40B650 produces much less motion blur than the Toshiba Regza 40XV645U, but it actually produces more motion artifacts, which is rather remarkable given that the 40XV645U is not a good television in this regard.

Samsung UN32D5500 LED LCD HDTV Review
The D5500 has a rather high MSRP of $699, considering it’s only a 32-inch TV.

If you can find it a significantly reduced price it would make a great addition to a home theater. Read More...
