TV settings

Many consumers pay attention to the differences in the playback quality of TVs in stores. This is especially noticeable during simultaneous work of several TVs on one channel.

Unfortunately, modern TV manufacturers primarily are interested in increasing sales. Therefore, the optimal pre-settings are not a priority for some companies. Manufacturers often try to present in their TVs maximally “bright blue” and “red” colors, increasing the brightness of these colors. Marketers know that the buyers majority choose the brightest TVs or models with maximally deep color. However, the most TVs provide the similar playback quality when properly setting. This factor can be useful in choosing the optimal TV.

Main settings

The calibration provades the maximum correct image playback. This method uses a reference image at the TV input. The values of reference image parameters are compared with the image on the screen. Complex Delta E characterizes the deviation degree from standard color. For example, Delta E = 0 corresponds to the ideal setting. The reference colors are very deep, bright and saturated.

A calorimeter provides a measure of the color temperature of the output signal. Specialist achieves of the images identity on the screen with reference colors during the calibration process. Only top models usually provide full calibration. Typically, Delta E value after calibration is 2-3. The human eyes do not perceive such distortion. However, this calibration is laborious, requires knowledge and equipment.

The TVs are adjusted before the maximum possible identity to international standards. The TV must minimally to distort the original content that is always created on basis of standards or recommendations. Correct playback of the sky at sunset, skin color of actor and the image details provides realness.

Abbreviations PAL, NTSC or HDTV are designation of these standards. They contain requirements and recommendations to the video signal parameters and the allowable values of various image parameters. Most of the standards are outdated after the HDTV emergence.

Today OLED TVs provide maximum color gamut.

Main technical values

Values of main settings:

– color temperature of 6500K (D65);

6500 K is the approximate color temperature of the midday sun. White objects under such light have a certain color.

– gamma correction;

Gamma coefficient determines the ratio between the numerical value of the pixel and its actual luminosity. Correctly set gamma correction provides proportional reproduction of halftones in the whole range.

The recommended value is 2.22 (or 2.4 in the darkened room);

– brightness;

Brightness provides clarity and saturation of the image in external lighting.

The recommended brightness of about 120 cd / sq.m.

A list of settings that do not require the use of special hardware settings includes:

Picture Mode (Standard / Dynamic / cinema);

mode of color temperature (cool / normal / warm);

tripping of some settings;




color / saturation;

Motion-Compensated Frame Interpolation (MCFI).
