Blacks & Whites

It's a tight race in the competition between these two HDTVs in our tests that lok at black levels, white levels and the contrast ratio between the two. The Sony has the lower black level (so it will have deeper blacks), but the JVC has brighter whites. This means that the JVC has a wider contrast ratio between the two, but the differences are not that significant. Bascially, they both do a good job of showing deep blacks and bright whites.

Color Accuracy

On our tests on the performance of the displays with colors, it was again a pretty close race; the JVC did slightly better in our color temperature tests (which look at how constant the whites are), but the other tests were pretty close. Both had slightly bumpy RGB response curves (which could mean false contouring and banding in subtle colors on the screen) and has slightly inaccurate color gamuts. But neither TV was particularly awful; both had decent color performance.

Motion

Both TVs also produced decent motion, with smooth on-screen images and only slight artifacts; we saw some issues with sharp, fast moving edges on the Sony having a slight forward shadow, while some colors on the JVC became somewhat flat and cartoonish.

Viewing Effects

The Sony had a significantly wider viewing angle than the JVC; we found in our tests that the contrast ratio of the Sony fell by 50% at about 30 degrees away from straight on, while the JVC only managed 30 degrees on the same test. This means that the Sony will look better for those on the ends of the couch, or if it is used as an office display in a large conference room.

Connectivity

The Sony has a wider selection of inputs and outputs, including more HDMI ports and an antenna/cable input. This makes it more flexible, as you can connect more devices and also watch over the air HD signals without an external decoder.

Other Comparisons

The JVC has one feature that the Sony does not: support for the Adobe RGB color gamut, which allows it to display a wider range of colors than the Sony.
