Sony Bravia KDL-32BX300

Color Temperature (6.35)

The Sony KDL-32BX300 managed to maintain a consistent color temperature for most of the input range. However, as the signal got very low (or ‘dark’ in common parlance) the color temperature became much cooler. It’s limited to such a small portion of the spectrum that you probably won’t notice the issue very much. More on how we test color temperature.

RGB Curves (7.73)

The Sony KDL-32BX300 had to be put through more than one run of testing in order to get the best scores. On our first run, we noticed a reddish hue to the whites. It was hard to miss, even to the naked eye. When we ran color tests, we noticed the RGB curves peaked very early and the color temperature test fared poorly. Occasionally, you’ll see problems like this on cheaper TVs. But you don’t always have the tools in the menu to correct them. The Sony KDL-32BX300 is the rare instance wherein you have a cheap TV with a comprehensive set of controls. It’s a bit unusual from our normal procedures, but we entered the ‘color temperature’ submenu and decreased the Red-channel gain from 0 to -30. To the eye, this was about the point where the red hue disappeared.

When we re-ran the color tests with this modified calibration, the performance was much improved. The Color Temperature test results were described in the section above. The RGB curves are shown below. As you can see, they’re not perfect. Each channel peaks early, but not nearly as early as in our original tests. The green channel loses the most information in the highlights, and the blue channel loses the least.

In the lower-left hand side of the RGB curves indicate the lack of shadow detail. This is unfortunate, but it coincides with what we found in the Greyscale Gamma test. The Sony KDL-32BX300 is simply not a great V for shadow details. More on how we test RGB curves.

Color Gamut (5.35)

The Sony KDL-32BX300 performed very well when matched up against the rec. 709 color standard, a common industry benchmark for color accuracy. The red point is almost perfect, and the green and blue points are only off by a little. More on how we test peak color gamut.

The table below contains all the numeric details of the Sony Bravia KDL-32BX300’s color gamut performance, compared to the rec. 709 standards.
