Samsung LN46B630 46-Inch LCD HDTV is the big brother of Samsung LN46B550 which was also a feature packed HDTV. It comes as a product few steps ahead of the previous model. It is also a full HD TV with 1080p, but the dynamic refresh rate has been upgraded to 120 Hz along with an exceptional response time of 4 milli seconds. So the end product is certainly a powerful LCD TV with great performance and equally impressive picture rendering capabilities. 
The 120 Hz refresh rate ensures there is no more blurring effect, while the fast response time makes it a suitable candidate for the people looking for a TV who prefer watching action packed movies or who happen to be avid gamers. So now you can sit back and enjoy your favorite movies or games to the fullest with immersive picture clarity and rich detailed videos.
The contrast ratio too has been upgraded to 80000:1 which means more enhanced details. The difference is more than noticeable as compared to Samsung LN46B550 which has 70000:1 contrast ratio. Coming in a matte screen it is perfect for a room which has enough ambient light. All in all a very good product, and it is certainly appropriate for its price.
