What is dcr on a monitor?

Dynamic Contrast Ratio (DCR) is a specification advertised on some monitors and televisions. It refers to the ratio of the luminance of the brightest white to the luminance of the darkest black that the monitor can produce over time. Unlike static contrast ratio, which measures contrast within a single frame, DCR is a dynamic measurement.

Here's a breakdown:

• What it is: <a href="https://www.wikiwhat.page/kavramlar/Dynamic%20Contrast%20Ratio">Dynamic Contrast Ratio</a> (DCR) is a marketing term that describes how much brighter the monitor can get in a very bright scene compared to how dark it can get in a very dark scene. The monitor automatically adjusts the backlight intensity to achieve these extremes.

• How it works: DCR works by dimming the backlight substantially or even turning it off completely during dark scenes, and boosting the backlight significantly during bright scenes.

• Why it's used: Manufacturers use DCR as a selling point, as the numbers often appear very impressive (e.g., 10,000,000:1).

• The catch: DCR figures are often misleading. The advertised DCR is not representative of the contrast ratio you'll experience in typical viewing conditions. The actual, or static, contrast ratio is a more accurate measure of picture quality.

• Importance: DCR is generally not a critical factor in choosing a monitor. Focus on other specifications like <a href="https://www.wikiwhat.page/kavramlar/panel%20type">panel type</a>, resolution, refresh rate, response time, and, importantly, the static contrast ratio. Static contrast ratio provides a better indication of the display's ability to render subtle differences in dark and bright scenes simultaneously.
