Sit and work for showing wellthe monitor wants all the people, especially if it qualitatively conveys all the color shades and details of the image both in the light and in the shade. It is in order to adjust the monitor to such a state that special calibrators are needed - hardware programs that use certain metric sensors and software. They are recommended for use in professional works with color shades.
Program to calibrate the monitor Samsung and other manufacturers
However, calibrators are expensive, and usethey can only specialists in computer business. For ordinary users, special programs have been created that help to customize the display, while using the natural indicator of nature - the human eye. Such a program for calibrating the monitor uses certain test images and the parameters and functions of the video card, giving the operator the task of monitoring the accuracy and correctness of the adjustment.
Customizable features are most oftensettings for 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 start calibrating a laptop monitor and a PC
Setting the display start with the arrangement of the workplace. Its external lighting should be constant and directional. The main thing is that the light does not shine into 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 soothing tones to ensure uniform lighting and color neutrality that does not irritate the eyes.
In addition, the calibration of the laptop monitor shouldpass on a heated monitor, which allows you to stabilize the backlight settings. For this, according to some research data, it must be kept on for 0.5-1.5 hours. In this case, all the various modifiers, especially those responsible for brightness and contrast, all image quality enhancers, should be turned off.
Many experts advise to pay close attention to the displays of laptops and monitors that support the TN + Film matrix, since the quality of the picture on these screens depends on the angle of inclination.
When calibrating such a monitor, the tilt anglethe display must be constant, otherwise the entire work of setting up will be in vain. After all, even a slight change in the viewing angle of the image greatly changes the test image.
Setup process
Monitor calibration at homeIt happens with the help of 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 the test images. Such patterns have a mesh or lattice look. The user, conducting changes in the settings of brightness, contrast and gamma, tries to achieve complete fusion of the image areas with the background.
However, it is worth bearing in mind that calibrationMonitor in the home is a time consuming process for a person’s vision, especially when using color substrates. For high-quality and accurate settings 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", so it is strongly recommended that the process of calibration periodically give the eyes a rest. But still, vision can only be given by subjective assessment, and therefore the result of the adjustment will also be subjective.
Expert Council
As shown by practical research, thoughtlessand ignorant actions on setting up a video system, during which the program is used to calibrate a laptop or personal computer monitor, often lead only to a deterioration in the quality of the picture shown. It is necessary to have a full understanding of what, how and why changes in settings will be made. 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 quality work on changing the parameters of displays.
Atrise Software LUTCurve application
Most experts agree thatThis utility is the best program for monitor calibration. It has a large set of functions for customizing screens. However, to maximize its capabilities, you must carefully study the instructions, which are written in English. For example, in the program description, owners of laptops and TN-matrix monitors are strongly advised to maintain a constant viewing angle on the display.
On the first page of the program are painted basicparameters of the arrangement of the workplace before setting up the display and are the rules for installing the system profile and colors. The application supports sRGB color space. The color temperature and gamma are set at 6500 K. The utility can work in a multimonitor configuration, producing fine tuning of any device.
Atrise Software Monitor Calibration SoftwareLUTCurve in its work relies on the maximum sensitivity of human eyes to gray. Therefore, all test pictures are executed in neutral colors.
Но программа обладает и своим недостатком – в ней There 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, which have already lost these settings. The advantage of this utility is the ability to adjust the gamma of the three elements in all 256 points. However, setting the parameters according to this data is a task for a patient person who has a lot of time available, and this method leaves a lot of subjective perception.
Eberhard Werle QuickGamma Utility
This program is for calibrating monitor colors andto adjust the gamma with a rate of 2.2. The set of functions and instructions are minimal. More complete information on setting can be obtained in the Help menu. There are also links to the necessary applications for the program.
The test picture is executed in the formhorizontal columns. Calibration occurs on the principle of orientation of the degree of their merger with the background. It is difficult for the eyes, especially if the picture acquires the color component of the RGB-substrates.
TFT Test 1.52 program
This application has a set of 12 pictures foradjustments and comparisons of displays. The utility contains sample data to verify 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 calibration quality of brightness and contrast and the quality of reproduction of midtones. To monitor the performance of liquid crystal screens, two tests for the response speed of the display elements are built into the program.
PassMark Software MonitorTest
This monitor calibration program contains 13test images that are designed to customize simple and LCD displays. These test images allow a professional, using the monitor, to adjust the gamma parameters so that the displayed picture detail has the correct appearance in a large range of brightness.
The only drawback of the application is that it does not have tools for configuring LUT-video cards, all changes are made only through the “menu” of the monitor.
It is necessary to remind that testing onThe 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 designed for old models of monitors, for new modern models, this frequency is already insufficient for testing.
The result
Programs for setting up monitors exista lot, but each of them assumes that the user has the ability and knowledge to use. As it was already said in the article, if a person does not know how to use the tools of the calibration utilities, then it is better to leave the factory settings alone. Well, if you still need to make color adjustments, especially on older monitors that have outdated, and there is not enough knowledge how to do this, then it is better to contact specialists who will calibrate safely and harmlessly. All the above programs and those that are not included in the review of this article are designed to work at a professional level. Not every user can customize his display with these applications.
