A program for calibrating the monitor at home

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

However, calibrators are not expensive, and only computer specialists can use them. For ordinary users, special programs are created that help customize the display, using a 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 to control the accuracy and correctness of the adjustment.

Adjustable functions are most often parameters of brightness, contrast and gamma. The last parameter is responsible for the screen response to the set values based on 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 your laptop and PC monitor

Adjustment of the display begins with the arrangement of the workplace. Its external lighting must be constant and directional. The main thing is that the light does not shine in the operator's eyes 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 background background should be equipped with quiet tones to ensure uniformity of illumination and color neutrality, which does not irritate the eyesight.

In addition, the calibration of the laptop monitor should take place on a warm monitor, which allows you to stabilize the backlight settings. For this, according to some research data, it should be kept on for 0.5-1.5 hours. In this case, all the various modifiers, especially responsible for brightness and contrast, all image quality amplifiers, should be turned off.

Many experts advise paying close attention to displays of laptops and monitors supporting the TN + Film matrix, as the quality of the picture 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 adjustment work will be in vain. After all, even a small change in the viewing angle of the image greatly changes the test picture.

Setup process

Calibration of the monitor at home is done with the help of special programs that are based on changing the image settings by the monitor and software equipment, while monitoring the result of changes in the appearance of test pictures. Such patterns have a mesh or lattice appearance. The user, making changes in the settings of brightness, contrast and gamma, tries to achieve a complete fusion of the sections of the image with the background.

However, it should be borne in mind that the calibration of the monitor at home is a laborious process for human vision, especially during the period of using colored substrates. For a high-quality and accurate setup, 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 strongly recommended to periodically rest your eyes during the calibration. But still, vision can give only subjective evaluation, and hence the result of tuning will also be subjective.

The Council of Experts

As shown by practical studies, thoughtless and ignorant actions to configure the video system, during which a program is used to calibrate the monitor of a laptop or a personal computer, often lead only to a deterioration in the quality of the picture depicted. 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, it is better to leave all the factory settings, especially for displays that already have a decent work record.

Now we will consider popular and well-known programs that help to make a qualitative work on changing the parameters of displays.

Atrise Software LUTCurve

Most experts agree that this utility is the best program for calibrating the monitor. It has a large set of functions for customizing screens. However, in order to take full advantage of its capabilities, it is necessary to carefully study the instruction, which is written in English. For example, in the description of the program to owners of laptops and monitors of TN-matrices it is strongly recommended to keep a constant angle of view on the display.

On the first page of the program basic parameters of arrangement of a workplace before adjustment of the display are painted and there are rules of installation of a system profile and colors. The application supports the color space sRGB. The color temperature and gamma are set at 6500 K. The utility can work in a multi-monitor configuration, making fine tuning of any device.

The program for calibration of the monitor Atrise Software LUTCurve in its work relies on the maximum sensitivity of human eyes to gray color. Because all the test images are executed in neutral tones.

But the program also has its drawback - it does not have a hardware sensor. Its settings are based on the factory brightness settings, which are set by the manufacturer in the display settings. But very often this method gives negative results, especially on old or used monitors, in which these settings have already gone astray. The advantage of this utility is the ability to adjust the gamma by three elements in all 256 points. However, setting parameters for these data is a task for a patient person who has a lot of time, and this method leaves a lot of subjective perception.

This program to calibrate the colors of the monitor and to adjust the gamma with a score of 2.2. The set of functions and instructions are minimal. For more information on setting up, go to the Help menu. There are also links to the necessary applications for the program.

The test image 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 hard for the eyes, especially if the picture gets a color component from the RGB-substrate.

TFT Test 1.52

This application has a set of 12 pictures for adjusting and comparing displays. The utility contains sample data to verify screen resolution, accuracy, and geometry. The program for calibrating the TFT Test 1.52 with its gray and color, linear and circular gradient saturation gradients allows you to compare the quality of the calibration of brightness and contrast and the quality of reproduction of halftones. To monitor the speed of LCD screens, the program has two tests for the response rate of display elements.

PassMark Software MonitorTest

This program for calibration of the monitor contains 13 test images, which are intended for the adjustment of simple and LCD displays. These test pictures allow the professional, using the monitor's tools, to adjust the gamma parameters so that the displayed detail of the picture has a correct view in a large range of brightness.

The only drawback of the application is that there are no tools for setting up LUT graphics cards, all changes are made only through the monitor's "menu".

It should be recalled that testing for the speed of the components of LCD screens and electronic displays has a number of contrasting objects that simultaneously move at different speeds. But, according to experts, the frequency of movement is calculated for old models of monitors, for new modern models this frequency is already insufficient for testing.

The result

There are a lot of 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 tools, it is better to leave the factory settings at rest. Well and if all the same it is necessary to make color correction, especially on old, the monitors which have served, and knowledge how it to make, does not suffice, it is better to address to experts who safely and harmlessly will carry out calibration. 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 with these applications.
