All people want to sit and work at a well-showing monitor, especially if it qualitatively conveys all color tones and image details both in light and in shadow. It is in order to configure the monitor in such a state that special calibrators are needed - hardware complex programs that use certain metric sensors and software. They are recommended for professional use with color shades.

However, calibrators are not cheap, and only computer experts can use them. For ordinary users, special programs have been created that help customize the display using the natural natural indicator - the human eye. Such a program for calibration of the monitor uses certain test images and parameters and functions of the video card, giving the operator the task of controlling the accuracy and correctness of adjustment.
The most commonly configured functions are brightness, contrast and gamma. The last parameter is responsible for the response of the screen to the set values according to the color of the image and its intensity. For the most part, the standard gamma coefficient adopted for the Windows system is 2.2.
How to calibrate a laptop monitor and PC
Display setup begins with the arrangement of the workplace. Its external lighting should be constant and directed. The main thing is that the light does not shine in the eyes of the operator and does not create glare on the display.
Great importance is given to the color of lighting. Most experts recommend ordinary lamps or fluorescent. Even such a detail as a screen background should be equipped with calm tones to ensure uniform lighting and color neutrality, which does not irritate vision.
In addition, the calibration of the laptop monitor should take place on a warm monitor, which allows to stabilize the backlight. To do this, according to some research data, it must be kept on for 0.5-1.5 hours. At the same time, all the various modifiers, especially those responsible for brightness and contrast, all image quality amplifiers, must be turned off.
Many experts advise close attention to the displays of laptops and monitors that support the TN + Film matrix, since the picture quality on these screens depends on the angle of inclination.
When calibrating such a monitor, the angle of the display should be constant, otherwise all the setup work will be in vain. After all, even a small change in the viewing angle of the image greatly changes the test image.
Setup process
Calibration of the monitor at home is carried out using special programs that are based on changing the image settings with the capabilities of the monitor and software equipment, while monitoring the result of changes in the appearance of test pictures. Such patterns have a mesh or trellised appearance. The user, making changes to the settings for brightness, contrast and gamma, tries to achieve complete merging of the image areas with the background.
However, it should be borne in mind that calibrating the monitor at home is a time-consuming process for human vision, especially during the use of colored substrates. For high-quality and fine-tuning, you will need to spend a lot of time in front of the computer display. At this time, the eyes can get the effect of "defocusing", therefore, it is strictly recommended to periodically allow the eyes to rest during the calibration process. But nevertheless, vision can only be given by subjective assessment, which means that the result of tuning will also be subjective.
Expert council
As practical studies have shown, thoughtless and ignorant actions to configure the video system, during which the program is used to calibrate the monitor of a laptop or personal computer, often lead only to a deterioration in the quality of the depicted image. It is necessary to have a full understanding of what exactly, how and for what changes will be made in the settings. If there is no such understanding, then it is better to leave all the parameters of the factory settings, especially for displays that already have a decent work experience.
Now we will look at popular and well-known programs that help to carry out high-quality work on changing display parameters.
Atrise Software LUTCurve App
Most experts agree that this utility is the best program for calibrating a monitor. It has a large set of functions for setting screens. True, to make the most of its capabilities, you must carefully study the instructions, which are written in English. For example, in the description of the program, owners of laptops and TN-matrix monitors are strongly recommended to maintain a constant angle of view on the display.
On the first page of the program the basic parameters of arranging the workplace before setting up the display are painted and the rules for setting the system profile and colors are found. The application supports sRGB color space. The color temperature and gamma are set at 6500 K. The utility can work in a multi-monitor configuration, fine-tuning any device.
The Atrise Software LUTCurve monitor calibration program in its work relies on the maximum sensitivity of the human eye to gray. Therefore, all test pictures are executed in neutral colors.
But the program also has its drawback - it lacks a hardware sensor. Its settings are based on the factory brightness settings that are set by the manufacturer in the display settings. But very often this method gives negative results, especially on old or used monitors, for which these settings have already gone astray. The advantage of this utility is the ability to adjust the gamma of three elements in all 256 points. However, adjusting the parameters according to these data is a task for a patient person who has a lot of time at his disposal, and this method leaves a lot of subjective perception.
Eberhard Werle QuickGamma Utility
This program is for calibrating monitor colors and for adjusting gamma with 2.2. The feature set and instructions are minimal. More complete configuration information can be obtained in the Help menu. There are also links to the necessary applications for the program to work.
The test picture is executed in the form of horizontal columns. Calibration is based on the principle of orienting the degree of their merging with the background. This is difficult for the eyes, especially if the picture takes on a color component from RGB substrates.
TFT Test 1.52
This application has a set of 12 pictures for adjusting and comparing displays. The utility contains sample data for checking screen resolution, accuracy and geometry. The TFT Test 1.52 monitor calibration program with its gray and color, linear and circular smooth saturation gradients allows you to compare the quality of brightness and contrast calibration and the quality of halftone playback. To control the speed of LCD screens , two tests for the response speed of display elements are built into the program.
PassMark Software MonitorTest
This monitor calibration program contains 13 test images that are designed to configure simple and LCD displays. These test images allow the professional, using the means of the monitor, to adjust the gamma parameters so that the displayed detail of the image has the correct appearance in a large range of brightness.
The only minus of the application is that it does not have tools for setting up LUT video cards, all changes are made only through the “menu” of the monitor.
It is necessary to recall that testing for the speed of components of LCD screens and electronic displays has a certain number of contrasting objects that simultaneously move at different speeds. But, according to experts, the frequency of movement is designed for old models of monitors, for new modern models this frequency is already insufficient for testing.
Total
There are many programs for setting up monitors, but each of them assumes that the user has the ability and knowledge to use. As already mentioned in the article, if a person does not know how to use the tools of calibration utilities, it is better to leave the factory settings alone. Well, if you still need to make color adjustments, especially on old, old-used monitors, and there is not enough knowledge on how to do this, then it is better to contact specialists who will safely and harmlessly calibrate. All the above programs and those that are not included in the review of this article are designed to work on a professional level. Not every user can customize their display using these applications.
