A program for calibrating the monitor at home

Sit and work for a good showingthe monitor is wanted by all people, especially if it qualitatively transfers all color shades and details of the image both in light and in the shade. 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 usethey can only specialists in computer science. 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.

Customizable functions are most oftenparameters 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 uniform illumination and color neutrality, which does not irritate the eyesight.

In addition, the calibration of the laptop monitor shouldpass on the warmed-up 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 matrix TN + Film, as the quality of the picture on these screens depends on the angle of inclination.

When calibrating such a monitor, the angle of inclinationthe display must 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

Calibrating the monitor at homeoccurs using special programs that are based on changing the image settings of the monitor and software, while monitoring the result of changes in the appearance of test images. 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 is worth bearing in mind that the calibrationmonitor 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 process. But still, vision can give only subjective evaluation, and therefore the result of tuning will also be subjective.

The Council of Experts

As shown by practical research, thoughtlessand ignorant actions to configure the video system, during which a program is used to calibrate the monitor of a laptop or personal computer, often lead only to a deterioration in the quality of the picture shown. 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 thatThis utility is the best program for calibrating the monitor. It has a large set of functions for customizing screens. However, in order to make the most 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 notebooks and monitors of TN-matrices it is strongly recommended to keep a constant angle of view on the display.

The first page of the program lists basicparameters of arrangement of a workplace before adjustment of the display 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.

Atrise Software Monitor Calibration SoftwareLUTCurve in its work relies on the maximum sensitivity of the human eye to gray color. Because all the test pictures are executed in neutral tones.

But the program also has its drawback - in itthere is no 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 are already lost. The advantage of this utility is the ability to adjust the gamma by three elements in all 256 points. However, setting parameters on 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 is for calibrating the colors of the monitor andto adjust the gamma with a score of 2.2. The set of functions and instructions are minimal. More complete information on setting can be obtained from the "Help" menu. There are also links to the necessary applications for the program.

The test picture is executed in the formhorizontal columns. Calibration is based on the principle of orienting the degree of their merging with the background. It's hard for the eyes, especially if the picture gets a color component from RGB-substrates.

TFT Test 1.52

This application has a set of 12 images foradjustments and comparisons of 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 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 speed of the display elements.

PassMark Software MonitorTest

This program for calibrating the monitor contains 13test images that are designed to configure 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 form in a large range of brightness.

The only disadvantage 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 forThe 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

Programs for configuring monitors exista lot, but each of them assumes that the user has the ability and knowledge to use. As already said in the article, if a person does not know how to use the tools of calibration tools, then 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.
