Blacks & Whites

Both TVs had pretty dark blacks, but the Samsung had a bit of an edge; it managed a black level of 0.07 cd/m2, while the JVC was at 0.1 cd/m2. The Samsung also had a slightly higher peak white, and this combination leads to a  wider contrast ratio.

Color Accuracy

The LT-42WX70 had the edge on color; it had lower overall color temperature change, and the color gamut was more accurate. The RGB curves were significantly bumpier on the JVC, though, which could lead to more banding and contouring on the screen.

Color Gamut Comparison

JVC LT-42WX70 Score: 5.14

Samsung LN40B650 Score: 4.23

Motion

The Samsung was the superior TV in displaying motion; thanks to its 120Hz processing, we saw smoother motion, and fine details in this motion were better maintained when they were moving rapidly across the screen. The Samsung also did a better job of processing a 3:2 pulldown signal, a process where a broadcaster processes a signal to give it a more filmic look. Neither TV had a problem showing a 24 frames per second signal produced by a blu-ray player, though.

Viewing Effects

The JVC had a slightly wider viewing angle, but only by a few degrees. Frankly, neither HDTV does particularly well in this test; both have very disappointing viewing angles.

Viewing Angle Comparison
JVC LT-42WX70 Score: 5.23	Samsung LN40B650 Score: 4.55

Connectivity

The Samsung is the more connected TV by a long stretch; it has more HDMI prots, more analog inputs and a cable/antenna input that means it can work without a cable or set-top box.

Other Comparisons

The JVC has one thing that the Samsung doesn't, though; the wider color gamut. However, as our tests show, it doesn't cover the complete Adobe RGB gamut, so this feature is a little less enticing than it forst appears.
