Value Comparison Summary


The Samsung LN50B650 bests the 37LH55 in many, many categories. While it lacks a 240Hz refresh rate, it does have a 120Hz mode, which will be more or less the same for most consumers. It's slightly bigger, has better overall picture quality, and costs less.

Other Comparisons


The LN40B650 gains a pretty big advantage here by coming with internet connetivity. You can use this feature to stream content off your computer or download and install widgets on the TV. This is a nice feature, and certainly better than the 37LH55's lack of internet connectivity, but not nearly as good as some higher-end internet-capable TVs that can stream video from popular content providers.

The 37LH55 counters this by offering 240Hz playback.
