What are the noteworthy parameters of the photographic selection retouching display?

Generally, when purchasing a photographic retouching display, there are two main parameters worthy of attention: color accuracy and color gamut. (Panel type, color depth, backlight, supported interfaces, resolution and size are not a big problem when the following two parameters are the key points, so they are omitted here. )

Color scales Δ e and Δ e (Δ e) are common standards (chromatic aberration) used to measure the color accuracy of displays in professional fields. Simply put, it is the difference between the color parameters given by the software to the display and the color actually displayed by the display. The smaller the deltae value, the more accurate the color. Generally speaking, the DeltaE value can be measured by a color calibrator. Therefore, the smaller the value, the better. The higher the score, the more distorted the color.

The color gamut here refers to the sum of colors that the display can produce. Everyone seems to have no idea about the percentage of color gamut. In fact, color gamut can be considered as color space in most cases, and RGB color gamut represents the specific color situation of RGB color space that a color image can express. There are three common color gamut standards: sRGB, AdobeRGB and NTSC. In case of retouching, the color gamut should cover at least 100%sRGB except Apple's monitor. Of course, the display used for retouching should be calibrated.
