How to Adjust Computer Display Tones to Normal
Adjusting the computer display tones to normal is essential for accurate color representation and a pleasant viewing experience.
Calibrating the Color Temperature: The color temperature of a display is a key factor in determining the overall tone. It is measured in Kelvin (K). A color temperature that is too high (towards the blue end of the spectrum) can make the image look cold and harsh, while a color temperature that is too low (towards the red end) can give a warm and yellowish tint. The ideal color temperature for most applications is around 6500K, which is considered a neutral white. Many operating systems provide built in tools to adjust the color temperature. For example, in Windows, you can access the display settings and look for the color calibration option. This allows you to adjust the color temperature slider to achieve a more natural looking white point.
Gamma Correction: Gamma refers to the relationship between the input signal and the brightness of the output on the display. Incorrect gamma settings can lead to washed out or overly dark images. A gamma value of around 2.2 is considered standard for most computer displays. Some graphics cards also come with their own software for gamma adjustment. You can use test patterns, such as a grayscale ramp, to visually assess and adjust the gamma. By making the mid tones of the grayscale look correct, you can ensure that the overall tonal range of the display is accurate.
Color Saturation and Hue: In addition to color temperature and gamma, adjusting the color saturation and hue is important. Color saturation refers to the intensity of the colors, and hue determines the actual color itself. Over saturated colors can look unnatural, while under saturated colors can make the image look dull. Most display settings allow you to adjust the saturation and hue levels. You can use color accurate reference images or test patterns to fine tune these settings. For example, a color checker chart can be used to match the colors on the display to the known accurate colors of the chart. By carefully adjusting these three aspects color temperature, gamma, and color saturation/hue you can bring the computer display tones to a more normal and accurate state for better visual performance.
