On TVs, regardless of the brand, there are standard picture settings; some settings control image quality at the physical level, such as brightness.
Most of the settings work at the software level by performing a certain image correction. The number and quality of such settings depends on the TV software. Some TVs of such settings can be 10-40, manufacturers producing low-cost TVs are usually limited to the minimum number of settings.
Most of the software settings are not used, and when using the TV as a monitor for games, they are completely turned off when the TV is switched to game mode.
Depending on the TV model, the settings may vary.
General image settings
|Contrast||100%||program||The contrast is set to maximum, this setting exists for a very long time, mainly depends on the quality of the screen matrix, this is the ratio of brightness between the black and white images. The higher the ratio, the better the image will be.|
|Brightness||50%||hardware||adjusts the brightness of the screen backlight, control the backlight LEDs. We set the average value, a very small level, make the image dark, a high level of brightness will distort the quality of the color, the image will be faded. With a strong bright room lighting, sometimes you have to set overestimated values at the expense of color reproduction.|
|Backlight||100%||hardware||This setting is in some TVs, an analogue of brightness.|
|Sharpness||0%||program||It does not carry any benefit, programmatically around bright objects creates a dark halo shading bright objects, visually makes the perception of the image more detailed, but creates additional noise around objects.|
|Picture mode||standard||program||There are several modes sport, cinema, standard, dynamic, at the discretion of the manufacturer there may be other values. Image presets, dynamic - increased brightness and contrast, cinema - softer image reduced brightness.|
|Gamma||2.2||program||Correction of the level of halftone, allows you to distinguish more details on the dark areas of the image.|
|Aspect Ratio||16:9||program||image size with a certain aspect ratio, is now mainly used standard 16: 9, and TVs have an aspect ratio of 16: 9. The choice of this ratio allows you to display the image on the whole screen.|
Advanced Image Settings
There are a lot of additional settings and their number depends on the type of TV and the installed software. But as a rule, all these settings are practically useless as they work only at the program level and may not always work correctly.
And also it is necessary to take into account that in the era of digital television, the quality of digital content is very high and initially the video is of very high quality; additional settings are simply not needed.
