Value Comparison Summary


The LN40B650 sits higher up Samsung' product lineup than the KDL-40S5100, and you can see this from the specifications as it features 120Hz refresh rate and USB connectivity, neither of which are available on the Sony model. From a performance standpoint both models did reasonably well, but the Samsung has one of the best contrast ratios we've ever seen and that 120Hz refresh rate makes a big difference in motion performance. If your budget can afford it we say go with the Samsung as you get a lot for your extra money.

Connectivity


The Samsung model definitely offers better connectivity options compared to the Sony KDL-40S5100, not surprising for a more expensive television. There's one additional HDMI input, but you also get internet connectivity via an ethernet port and two USB ports for viewing media. This is definitely a win for the Samsung LN40B650.
