Insignia NS-L37Q-10A

Color Temperature (9.55)

When we calibrate the TV, we make sure an all white screen has a color temperature that's as close to the ideal 6500K as we can get it. Unfortunately, this doesn't ensure the TV has a perfectly consistent color temperature. Ideally this temperature will be maintained throughout the greyscale, but typically it shifts around a bit. For this test we measure the color temperature of each color in the greyscale to determine if there are any noticeable shifts.

Fortunately we didn't see anything worth worrying about on the Insignia NS-L37Q-10A. There were a few areas where it peeked over the perceptible limit, but it was such a minor breach it won't bother anyone.

RGB Curves (7.38)

Since all of the colors on your TV are constructed from red, green, and blue, we test each of those colors' performances individually.

The Insignia NS-L37Q-10A had a decent performance on this test. The curves shown in the graph below, have a good shape to them, meaning the colors will progress from low to high intensity at an appropriate pace. While the overall shape of the curves isn't a problem, note the stair stepping along each of the lines. There's a loss of detail in these areas: the TV is being told to display different intensities of color, but is instead displaying the same one for both. While not a giant issue, this can lead to images looking a bit flatter than they should, or create striations in areas of a smooth transition between colors.

Also, note the flat top to the green and blue curves. This is peaking, which means there's no differentiation between colors along that plateau. This means there won't be any high-intensity details for either color.

Color Gamut (5.49)

The colors each TV displays have been set by an international standard, called rec. 709. This standard is a firm set of guidelines that televisions continually ignore for their own reasons. We therefore measure the red, green, blue, and white points of each TV, and stack it up against rec. 709.

The red is pretty much spot on, but the greens are oversaturated and the blues are pushed towards aqua.

Below we've listed the points we measured, the rec. 709 standard, and how far off the TV was. If you're not a cinephile, you probably won't care about this data.
