More often than not, a TV without a wide color gamut has bad tone mapping because it can't display the colors as needed, but it's also possible a TV with a wide color gamut has bad tone mapping (like the LG B1 OLED). It's basically telling you how accurate the display is with the colors in the color space. This is the tone mapping, and it measures the standard deviation of each color compared to the color it's supposed to display. In the photos above with the color gamuts of the Vizio TVs, there are horizontal bar graphs on the left. You can see that the P Series displays the primary colors a lot better (especially green), and colors are more accurate.Īlthough we only publish the results for the color space, we also measure the tone mapping using the CalMan software. The color volume tests use this 3D space, but we don't measure the color gamut coverage with it.īelow you can see fantastic coverage on the Vizio P Series Quantum 2021 (left) and only good coverage on the Vizio V5 Series 2021 (right). This measurement is done in a 2D space, so it's not as accurate as measuring a 3D space, but that's nearly impossible to do because it would require millions of measurements. As you see below, it's where the triangle (CIE xy) meets the more circular shape (DCI P3), and it measures how much of the area the TV covers the higher the percentage, the better. The DCI P3 xy represents the intersection between the DCI P3 color space and the TV's boundaries, using the CIE 1931 xy color space.

The CalMan software analyzes six colors (red, green, blue, yellow, magenta, and cyan) and measures them at different saturations to measure the color gamut and the tone mapping. The DCI P3 color space is the color space most used in HDR content, and most 4k HDR TVs have at least good coverage of it.
