LG 32LG70

Color Temperature (9.98)

When we calibrate our TVs, we try to get the color temperature as close to the ideal 6500K as we can. Unfortunately, calibration can only get you so far. Typically color temperature will shift around slightly throughout the greyscale. If the TV is good, these shifts won't be perceptible, or, if they are, those shifts will be so small and brief they won't realistically be noticed. You start running into issues when these shifts are very noticible, or extend over a long span of the greyscale.

Fortunately, the LG 32LG70 had a solid color temperature. The only shift that's remotely perceptible is towards the black end of the spectrum, where the temperature drops just barely low enough to technically classify as 'warm.' This blip won't be noticeable during normal use.

RGB Curves (7.73)

Thanks to the physics of light, every color on your TV can be constructed from some combination of red, green, and blue. Since these three colors are so important, we test them separately. We feed the TV varying intensities of each, then record what's being displayed. Ideally, these points of data should construct a smooth curve. Any 'stair-stepping'in the line represents an area of lost detail, since the TV is essentially displaying the same shade of a color for two different intensities.

In the graph below, you'll see a lot of stairstepping. The curves themselves look bumpy, meaning an uneven progression of black to high-intensity color. Although the red channel was a bit slower to intensify than the green and blue channels, it showed far less peaking. Note how, towards the higher intensities, green's curve plateaus considerably and blue outright flattens.

Color Gamut (4.73)

The range of colors a TV displays are set by an international standard, called rec. 709. This standard dictates the red, blue, green, and white points all TVs should be displaying. We take our own measurements of the TV's performance and compare them up to rec. 709 to see how well they adhere to the standard.

The LG 32LG70 follows the standard fairly well, by having near-perfect white and red points. The green point is skewed a bit towards blue, however, and the blue point is oversaturated and pushed towards red.
