Color Accuracy

Smooth RGB color curve. Problem maintaining consistent color temperature.

The Sony KDL-52EX700 could have managed a better score here in the color temperature consistency test. The image had a problem with warming as it moved through the intensity range. Practically speaking, you might be able to look at the screen and say, ‘this looks a bit warm,’ but whether or not that negatively impacts your viewing experience is up to what kind of cinephile you are. More on how we test color temperature.

The Sony KDL-52EX700’s color curves were not quite perfect. As you can see from the chart below, the red, green, and blue channels didn’t all quite meet up to form a single line, and each has its own little bumps. These bumps, in everyday viewing, would appear as areas of color banding. There are no major problem areas, but the blue channel probably looks the worst.

We also noticed the blue channel peaked, visualized by that horizontal tailing off at the top-right end of the blue line. This means that the KDL-52EX700 has trouble finding any detail in the brightest parts of the blue channel. More on how we test RGB curves.

The Sony KDL-52EX700 scored fairly well when we tried matching it up to the rec. 709 color standard. Look at the three corners of the triangle below. The green and blue points aren’t far off from the standard, but the red point is a bit undersaturated. More on how we test peak color gamut.

With its reasonably good performance in many categories and more internet features than you can shake an e-stick at, that question might be hard to answer if it weren't for this review.
