What is monitor dcr

In the last few years, a new acronym has emerged. It can be found in the characteristics of new TV models (released after 2017). It uses new technology to create image quality. This is done because movies and games are evolving and the demands on them are increasing. Nowadays, the technology is often used for monitors as it helps improve image quality.

What is monitor dcr

The abbreviation dcr sounds like dynamic contrast ratio. This means contrast ratio, in other words, high dynamic range. This indicator affects the screen's ability to convey a large difference in bright elements between the dark and bright parts of the picture. The image becomes better and more realistic. The detail of movie scenes is preserved. This is especially important because some TVs have brightness and contrast limits. At low contrast, dark shades of gray will appear as black, and at high brightness, some colors will appear white. Therefore, NVIDIA created DCR, breaking away from the following rules:

1. A bright image should always be bright.
2. Dark is always dark.
3. Details should be visible in both bright and dark pictures.

Why is DCR monitor needed?

Another concept related to ratio is rendering. It is needed so that the graphics can calculate the brightness of pixels that are transmitted in the highest range.Rendering will also allow you to preserve natural brightness and convey the properties of transparent materials, for example, glass or optical phenomena (refraction and reflection of light). In normal rendering, very bright light sources, such as the sun, are assigned a brightness factor of 1.0, which means white. But DCR rendering is capable of exceeding the coefficient of 1.0, and conveying the bright rays of the sun with better quality and detail. This was achieved by reproducing the reflection of rays from surfaces. The same goes for contrast. The human eye is capable of perceiving the darkest shades. Rendering renders them as high quality as possible. It follows that DCR is needed in order to make the image detailed.

When to use the parameter

Contrast is based on the ability of the screen to independently increase or decrease brightness. This indicator depends on the scenes shown (some should be as bright as possible). This is achieved by increasing the backlight strength. And if you need to make the image as dark as possible, the backlight can turn off completely. Manufacturers were able to set the contrast value at which the brightest shades (when the backlight is at maximum) and the darkest shades (when it is turned off) are compared. This technique became very common as the range became very high (difference from one to a million). This parameter should be used when you like to see this big difference in brightness. If not, it should be disabled.

Note! This technique did not make a huge contribution to the brightness-to-contrast ratio. The picture changes very quickly, and the human eye can rarely catch the difference.And if you compare one scene, the bright and dark areas look the same.

DCR is needed to obtain a dynamic image. Technology does not stand still, and image quality and performance will constantly improve.
