Samsung LN40B650 Comparison

The Samsung UN40B650 was one of our better contenders in 2009, based on solid performance numbers and a reasonable price. While it has no internet connection, the streaming content offerings from Sharp are hardly worth consideration. Considering the price difference, the Samsung is the better buy.

The Samsung UN40B650 showed the best black level and second-best peak brightness performance in our comparison pool. With a lab-tested contrast ratio of 5226:1, that’s among the best scores we’re seen in a 40-inch TV. The Sharp was no slouch, but it couldn’t match up.

Contrast Chart

The Sharp LC-40LE700UN managed to outperform the Samsung UN46B650 by a little in maintaining a consistent color temperature. You can see from the charts below that the Samsung had a penchant for warming at a few points in the signal intensity range.

The RGB color curve performances were much closer. Both TVs should produce smooth, satisfactory color gradations.

The Samsung UN40B650 showed good smoothness of motion, but we noticed a lot of artifacting. The Sharp LC-40LE700UN, on the other hand, had very little artifacting, and with the addition of features like ‘Fine Motion Enhanced,’ even further improvement (thought subtle) could be had.

Motion Scores

The Samsung UN40B650 is more or less matched with the Sharp LC-40LE700UN in terms of connectivity. Both have 4 HDMIs, while the Sharp has one additional composite and an S-video. The Samsung lacks the internet connectivity of the Sharp, but Sharp hardly makes use of it, so it’s a draw.
