Description

So, let's assume that you are the proud owner of a brand new monitor. Everything was observed when purchasing necessary measures precautions: the monitor was purchased from a well-known company, before purchase it was tested with a special program, more computer experienced friends helped you choose a monitor, etc. However, for the monitor to work successfully, it is not enough to simply plug it into the network and connect it to the computer: the device must be correctly tune.

ATTENTION

If you purchased the monitor in the cold season, then after delivery from the street you need to let it stand in a warm room for at least two hours. If this is not done, the monitor may fail, and warranty replacement or warranty repairs in in this case You probably won't have to count.

Setting up a monitor can be divided into two stages: hardware and software. Let's take a closer look at each of them.

Hardware level

To configure the monitor at the hardware level, there are buttons, which in the vast majority of monitors are located on the front panel. To call up the setup menu, most often press Menu button. The contents of this menu may vary depending on specific monitor. By the way, on very old monitors there is no setup menu at all.

NOTE

On some monitors, the setup menu disappears automatically after 10 seconds of inactivity.

I will list the items that are most often found in the monitor settings menu.

Some of them correspond to TV settings.

• ? Brightness and Contrast - these parameters are present in almost all modern monitors. It is difficult to recommend a specific level of brightness and contrast: these indicators are determined individually for each monitor. However, in any case, it is not recommended to set the maximum brightness and contrast (unless, of course, your monitor’s cathode ray tube begins to “shrink”).
• ? Horizontal position and Vertical position - here you set the centering of the image placement on the screen horizontally and vertically. For example, if an empty vertical bar appears on the left side of the screen, and the image on the right side extends beyond the visible area of ​​the screen, then you need to adjust the horizontal position of the image.
• ? Horizontal Size and Vertical Size - using these menu items you set the required horizontal and vertical size of the image. In other words, here you can “stretch” or “compress” the image horizontally or vertically, respectively.
• ? Cushioning - this menu item allows you to adjust the convexity or concavity of the image on the sides. Many users install for this parameter value 40.
• ? Geometric distortion - this menu item consists of several submenus, which include: Keystone, Parallelogram, Rotation, Balancing and Linearity. Each of these submenus is designed to configure a corresponding image parameter: for example, using the Trapezoid parameter, you can change the image into a trapezoid shape, etc.
• ? Language - in this menu item, select the language in which the contents of the monitor settings menu will be displayed.
• ? Special Features- this menu item contains several submenus designed to configure specific parameters, for example, horizontal and vertical moire, video signal level, etc. It is not recommended to change the values ​​of these parameters unless absolutely necessary.
• ? Magnification - by setting this parameter you can enlarge or reduce the image.
• ? Degaussing is a function designed to demagnetize the monitor. Periodic demagnetization helps to increase the service life of the device.

It should be noted that many monitor hardware settings have default values ​​that are acceptable for use.

Screen settings configured in the operating system

In addition to the built-in menu, there are some operating system parameters for setting up the monitor.

As noted above, to enter the screen settings mode, click on any free space Desktop and select Properties in the context menu that opens. In this case, a screen settings window will appear on the screen, consisting of the following tabs: Themes, Desktop, Screensaver, Appearance and Options. Let's look at the order of operation on each tab.

The contents of the Themes tab are shown in Fig. 2.9.

This tab is intended for selecting a desktop theme and interface elements. U inexperienced user The question may arise: what is a “topic” and why choose it?

The concept of “topic” includes the totality of all visual settings systems: window color design, icon appearance, taskbar, Start button menu, fonts used, mouse pointer appearance, etc. As part of a theme, these settings represent a single whole and determine general style design of the operating system interface.

Select the desired theme from the Subject drop-down list. Windows XP Professional comes with two themes out of the box: Windows XP (which is installed by default) and Classic (you can select this theme to return to the interface used in previous versions). Windows versions). If you want to use any other theme, select Browse from the drop-down list and in the Open theme window that opens, specify the path to the required theme file (the theme file has the THEME extension).

On the Internet you can find a wide variety of operating system interface themes (not only Windows XP, but also other systems). To reduce eye strain, it is recommended to choose a calmer theme, avoiding too bright designs, as well as animation, cartoon and similar effects.

The Sample field displays an example of the interface with the selected theme (for example, Fig. 2.9 shows the interface design with the Windows XP theme).

Using the Delete button you can delete the selected topic. I note that deleting themes that were originally installed in the operating system is impossible.

One of the most important elements of the operating system interface is the Desktop. We can say that this is the face of the operating system. The first thing we see on the screen after loading Windows is the Desktop, so setting it up should be taken seriously.

To switch to the Desktop settings mode, in the Properties: Screen window, go to the Desktop tab (Fig. 2.10).

As you know, the design of the Desktop largely depends on its background image, which is used as a kind of decoration. Background image The desktop is selected in the Background picture field, after which it is displayed on the sample (in Fig. 2.10, the Azure background picture is selected). After selecting the desired pattern, click Apply or OK.

The system's capabilities provide for the choice of a non-standard desktop background image. To do this, click the Browse button and in the window that opens, according to the usual Windows rules, specify the path to the picture file. You can use files of various types (BMP, GIF, JPG, etc.) as desktop background images.

If necessary, you can fine-tune the Desktop. To switch to the appropriate mode, click the Desktop Settings button, which is located under the Wallpaper field. OKI Yu Desktop Elements will appear on the screen, shown in Fig. 2.11.

This window contains two tabs: General and Web. On the General tab, in the Desktop Icons area, select Windows elements, icons of which should be displayed on the Desktop (to do this, check the appropriate boxes). You can control the display of the following icons: My Documents, My Computer, My Network Places, and Internet Explorer. In any case, it is recommended to enable the display of the My Computer icon.

If necessary, you can change the icons of items on the Desktop. To do this, in the field located under the Desktop icons area, you must select the required icon and click the Change icon button. As a result, the Change icon window will appear on the screen, in which in the Search for icons in field next file You should specify the path to the icon file and the file name. The Select icon from the following list drop-down list contains a selection of available icons (there can be multiple icons in one file). To select an icon, you must enter its path in the Look for icons in the following file field or select an icon from the Select an icon from the following list drop-down list, and then click OK (if the file contains multiple icons, you must do both). You can also use the Browse button to specify the path to the icon file.

At the bottom of the General tab is a checkbox next to Clean your desktop every 60 days. When this box is checked, the mode for automatically cleaning the Desktop from unused elements is enabled. To do this, use the Desktop Cleanup Wizard, which runs automatically every 60 days along with operating system. If necessary, you can use this wizard at any time by clicking the Clear desktop button.

On the Web tab, a list of web content on the Desktop is formed (the display of web elements can be enabled by checking the appropriate boxes). New elements can be added to the list using the Create button, and selected ones can be deleted using the Delete button. To switch to the mode of viewing and editing the properties of the selected element, click the Properties button. Use the Synchronize button to immediately update your Desktop web content. If you want to prevent web elements from moving on the Desktop, select the Lock desktop elements check box.

On the Screensaver tab (Fig. 2.12), select an image (usually moving), which is launched by the system automatically after the computer has been idle for some time. This interval is specified in the Interval field.

ATTENTION

The Interval field is editable only if any value other than None is selected in the Screensaver drop-down list.

The required image is selected from the Screensaver drop-down list. Like the Desktop tab, the selected image is shown at the top of this tab. If necessary, you can view the selected screensaver in full screen mode using the View button.

By clicking the Options button located to the right of the Screensaver field, you can switch to the mode for viewing and editing the properties of the selected screensaver. The appearance and composition of this window depend on the specific screen saver. For the Windows XP screensaver, which is selected in Fig. 2.13, there are no customizable parameters, and when you press the Parameters button, the system will display a corresponding message. This button is only available if the Screen Saver field is set to anything other than None.

Using the Power button, you can enter the mode for adjusting the monitor's power settings. At the same time, the Properties window will appear on the screen: Power Options, in which you select a power management scheme, set the time intervals after which the computer turns off the monitor and hard disks from power in the absence of activity, and also determine the values ​​of other parameters.

As already noted, the user selects a specific theme to design the Desktop and interface elements. However, there is often a need to fine-tune the design, for which a separate tab is provided (Fig. 2.13).

At the top of the tab, a sample design is displayed in accordance with the current settings (titles of the active and inactive windows, text in the window, etc.).

From the Windows and buttons drop-down list, select the desired window and button design style. The contents of this list depend on the theme selected on the Themes tab (see Figure 2.9). For example, for Windows themes XP from of this list You can select one of the following values: Classic style or Windows XP style.

From the Color scheme drop-down list, select a design color scheme. The contents of this list depend on the style selected in the Windows and Buttons list. For example, for Windows style The XP can be selected from Olive, Silver or Standard (blue) color schemes. The default color scheme is Standard.

The Font Size drop-down list contains options for the font size that can be applied to the selected color scheme. For example, for the Standard color scheme, this list contains the following values: Normal, Large font and Huge font, and for the Pumpkin color scheme (which can be selected if the Windows and Buttons option is set to Classic style) only one font is set - Large.

If necessary, you can configure certain display effects of interface elements, as well as other additional parameters. In order to switch to the appropriate modes, you should use the Effects and Advanced buttons located at the bottom right of the tab. Let's consider these modes in more detail.

For settings additional effects Click the Effects button, which opens the window of the same name (Fig. 2.14).

In this window, configure the following parameters.

• ? Once you select the Apply the following transition effect for menus and tooltips check box, a drop-down list is available from which you can choose whether to dim or expand menus and tooltips.
• ? The Use the following screen font smoothing method checkbox is only available if your video adapter and monitor support at least 256 colors. When you check this box, you can select one of the following values ​​from the drop-down list: Normal (this method is recommended for stationary desktop monitors) or Clear Type (designed for laptop computers).
• ? By checking the Use large icons checkbox, you enable the mode of using large icons for folders, files and shortcuts on the Desktop. This is convenient for people with low vision, but when this mode is turned on, fewer icons and shortcuts fit on the Desktop than usual.
• ? By checking the Show shadows checkbox, dropped menus enable the display of transparent shadows, giving the menu a three-dimensional appearance.?
• ? If the Show window contents when dragging check box is selected, the contents of the window will be displayed when you move or resize the window. If this check box is cleared, then when performing the specified actions, only the outline (borders) of the window will be displayed.
• ? When the Hide call indicators from the keyboard until pressed check box is selected designations of active objects (interface elements) will be hidden until actual movement through the system begins (usually using the Alt, Tab or cursor keys). I note that in most cases such designations represent a rectangle of dots that surrounds the active object (interface element).

Most effects, of course, improve the ergonomics of the interface and have other advantages, but the following must be taken into account: the fewer effects are enabled, the less strain on the user’s vision. To paraphrase a well-known saying, in this case we can say: “Simplicity is the key to health.”

To switch to the mode for setting additional design parameters, click the Advanced button on the Design tab (see Fig. 2.13). As a result, the Additional Design window will appear on the screen, shown in Fig. 2.15.

In this window, you can fine-tune the design of each individual interface element.

The Element drop-down list contains interface elements whose design parameters can be changed. These parameters are configured in the Size, Font fields and using the Color 1, Color 2 buttons. These parameters are available depending on what value is selected in the Element list. For example, for the Active Window Title element, you can configure all of the listed parameters. If in the Element list you select the Desktop value, then only the Color 1 button will be available (see Fig. 2.15), etc. To save the settings you have made, click OK in this window. Using the Cancel button you can exit this mode without saving changes.

Many important parameters are located on the Options tab (see Figure 2.7). First of all, the screen resolution and refresh rate are set here. How to configure these parameters is described above, in the subsection “The most important technical characteristics of the monitor.”

From the Color rendering quality drop-down list, select the desired monitor color rendering quality. In most cases it is appropriate to use the default value.

If there are malfunctions in the monitor's operation, you should use the Diagnostics button to troubleshoot possible problems. When you click this button, the Help and Support Center window will appear on the screen, where you can find the necessary information on the problem that has arisen.

To switch to the mode for setting additional parameters of the monitor and video adapter, use the Advanced button. When you press this button, the window shown in Fig. 1 will appear on the screen. 2.16.

This window consists of several tabs: General, Adapter, Monitor, Diagnostics and Color Management. In the Compatibility area of ​​the tab

General (it is open in Fig. 2.16) there is a switch that can take the following positions:

• ? Restart the computer with the new display settings - changes to the monitor settings take effect only after the computer is restarted;
• ? Apply new display settings without rebooting - changes in monitor settings take effect immediately after clicking the Apply or OK button on the Settings tab (see Fig. 2.7);
• ? Ask before applying new display settings - after changing monitor settings, the system will ask you to confirm the reboot.

Please note that some programs may not work correctly if you do not restart your computer after changing your monitor settings.

Please note that we will be talking about an approach for ordinary users; the article is not intended for professionals who have completely different requirements and costs for monitors.

Why set up a monitor?

The monitor is our eyes in the electronic world. It can be bad or good, in addition, the monitor can be configured incorrectly, which is usually the case. Have you seen the difference in color rendering between your TV and the TVs of your friends and relatives? If your TV/monitor is configured correctly and you pay attention to the colors in the monitors of your friends, you will immediately notice a difference in color saturation, increased contrast, and so on. On a properly configured monitor, you can see a maximum of color shades and brightness differences

Monitor settings, system defaults, stock cords, incorrect color profiles, stock drivers, and even monitor placement all play a role in setting up your monitor correctly. That is why, when looking at someone’s photograph on some monitor, you should not count on its correct color rendition - after all, photographers’ monitors may not be configured correctly. Achieving correct color rendering On an incorrectly configured monitor, the colors of the photo can be distorted. If you want to check how lying this or that monitor is, print out the photos.

Where to start setting up your monitor correctly?

First, remove anything that may interfere with the normal perception of color and color reproduction of the monitor. Place the monitor where no external lighting. It is advisable that there are no windows behind you, so that the light from the lamp does not fall into your monitor, either directly or at an angle. Professionals even have curtains that protect against light and glare; you hardly need curtains, but position your monitor so that no light falls on it.

How is the monitor connected? The monitor can be connected using a standard analog port VGA(blue plug and port) or via digital ports: DVI, HDMI DisplayPort or USB. If your computer and monitor have a digital port, connect through it. The transmission of digital data does not entail unnecessary interference, there is no conversion, it gives enough good difference contrast.

Setting up your monitor and video card- your computer will show the picture without installing any drivers for the monitor and video card, but it will be more correct if you install their “native” ones, fresh drivers(they are on the disks that came with your equipment or on official websites)

Monitor profiling - adjusting monitor color. If we already go to the monitor manufacturer’s website, then at the same time, download and install the color profile for the monitor. The color profile has a significant impact on color rendering.

The steps described above are not mandatory; individually they provide a small advantage, but together they will give a significant result.

Setting up the monitor

If you want to take this issue more seriously, you can rent a calibrator.

It is also worth knowing that once a correctly configured profile does not solve this issue forever, you need to monitor the correct color rendition of the monitor, since it may change over the course of its life.

There are also programs or websites (such as Lagom LCD) that you can use to test your monitor.

With their help you can configure your monitor. For example, to correctly adjust the brightness and contrast, look at the color plate above - we are interested in the bottom band with a gradation of gray. Ideally, you will see 32 rectangles with distinguishable edges between adjacent rectangles (and even the one on the far left should be different from the background). An excellent result will be if 32 gradations of all stripes are visible on your monitor, but if you can’t set it up like this, don’t worry, most likely you have a TFT TN matrix, that is, an inexpensive monitor for which this is normal.

So, adjusting brightness and contrast it happens like this:

• if the rectangles merge at both edges of the strip, reduce the contrast
• if the rectangles merge only on the left side of the strip, you need to increase the brightness; if on the right, reduce the brightness.
• if the rectangles merge only on one side, but after changing the brightness they begin to merge on the other side - increase the contrast
• Well, at the last stage, achieve a better result by gradually changing the brightness and contrast

Merging 1-3 rectangles is not critical if nothing better works out.

Naturally, after reconfiguring your monitor, it will seem to you that the contrast has weakened and the colors have faded. This Fine. You just got used to the previous setting, give your eyes time to readjust too, it will soon pass. Well, don’t forget, then, to set up the TV too, since you already know how to set up a monitor

Even the outstanding technical characteristics of a monitor do not guarantee that the image on the screen will be perfect. The quality of the picture depends on the display settings no less than on its electronic “stuffing”.

Factory settings in most cases do not allow the monitor to reach its full potential. There are three reasons for this.

1. Saving. The cheaper the display, the less attention the manufacturer pays to setting it up. And even enough expensive models(10–15 thousand rubles) are often configured far from ideally.

2. Individual differences between displays of the same model. At the design stage, the monitor components - matrix, backlight, control electronics - are adjusted to each other: backlight lamps are selected according to the emission spectrum and transmittance of the matrix subpixels, the control electronics sets the shape of the gamma curves, etc. However, the parameters of the components of a single monitor are always slightly different from the nameplate ones, and as a result, the image characteristics also “float”.

3. Background lighting. Factory settings are aimed at operating the display when certain color and brightness of background lighting. However, users have to work at the computer during the day when sunlight makes it difficult to see anything on the screen, then late in the evening, straining from the excessive brightness of the image. Yes, and the color of external lighting can change from bluish in lamps daylight to red at the “Ilyich light bulb”. As a result, the shades on the screen will also be perceived differently (the explanation for this is
see below for this phenomenon).

Incorrect settings lead to “crooked” color rendering. Most users don't notice how unrealistic the colors are on the screens they use every day. The human sensory system adapts to color distortions, and over time he ceases to see them. But if you put a “lying” monitor next to another, high-quality and correctly configured one, the difference in the image will be shocking: you may unexpectedly see that the faces in the photographs have an unhealthy blue tint, the grass is acid green, etc. In addition, when processing photographs on a monitor with incorrect color reproduction, the following unpleasant effect may occur: the user adjusts the colors in the photo, unknowingly compensating for the display's deficiencies, and as a result, the image is reproduced correctly only on this device. For example, if the monitor displays a picture with a blue tint, the user will turn down the brightness of this color in Photoshop and the photo will appear yellowish on other displays.

The second blow is taken by the perceived contrast: adjusting the electronics with incorrectly specified gamma curves makes the image faded and faded, or, conversely, too dark.

Fortunately, these shortcomings can be corrected. Most monitors allow you to customize image parameters within a wide range, and even with cheap models, color reproduction and contrast can be significantly improved. As for expensive displays, they can be adjusted with pinpoint precision, which allows them to be used even for professional color work.

At the same time, a well-tuned monitor is important not only for design, digital graphics and printing specialists. The pleasure of playing games or watching movies, as well as comfort when working with text and even the health of the user, depend on the correct settings. We owe chronic eye fatigue not only to constant sitting in front of a monitor, but also low quality Images.

Preparatory actions

Before you begin setting up your monitor, you need to let it run for about 15–20 minutes. During this time, it will have time to warm up, the backlights will go into regular mode work. In addition, you should clean the screen from dust and traces of touch. Use special ones for this wet wipes impregnated with an alcohol-based composition. They do not leave streaks and not only remove dirt well, but also provide antistatic protection for some time, protecting the screen from dust. It is helpful to read the manual that came with your monitor to understand the controls and available adjustments. Pay attention to the ability to move the menu from the center of the screen to its peripheral part– this may be needed during setup.

IN Display options Windows needs to set the correct values basic settings Images. IN Vista versions To access these parameters, right-click on Desktop, select “Personalization” from the drop-down list and in the window that opens, click on the “Display Settings” link. In Windows XP the same is enough context menu select “Properties”.

1. Move the slider in the “Resolution” section, setting the value corresponding to the “native” resolution of the display (in most cases, this is the maximum). Otherwise the image will be very blurry.

2. In the “Color Quality” menu, set the value to “Highest (32 bits)”.

3. Click on the “Advanced” button and in the window that opens, go to the “Monitor” tab. Select the maximum value from the drop-down list.

4. Close all open previous steps window by clicking the “Ok” button.

Setting up your monitor using the OSD menu

The easiest way to set up a monitor is to tinker with its on-screen menu. Unlike “ancient” displays on cathode ray tubes, the best models of which have a “wide” range of options, modern LCD monitors have an order of magnitude fewer adjustments available to the user (first of all, the image geometry settings have disappeared). Three of them are found in the menu of the vast majority of models and allow you to adjust the picture by eye, without using auxiliary “software” or additional hardware devices, although it is impossible to achieve a significant improvement in image quality in such a simple way.

1. Brightness . This parameter sets the overall backlight intensity of the image.

and equally affects both its darkest elements, up to black, and light ones, including pure white. Insufficient brightness makes the picture too dark, the difference between shades of similar intensity in the shadows becomes almost invisible (“shadows” and “highlights” are terms from professional photography, indicating the dark and light areas of the image), they merge with the black color. And too much brightness on displays with low contrast emphasizes “unreliable” black color. By increasing the brightness using the menu, it is necessary to achieve optimal reproduction of black on the screen, in which it remains quite dense, but shades close to it will be clearly visible. A photograph with a night scene taken with flash is perfect for this purpose.

2. Contrast. This setting should not be confused with contrast as a display characteristic.

Editing the corresponding OSD option will not deepen the blacks on the screen, but will only change the shape of the gamma curves. When too high contrast the picture looks too bright, “it hits the eyes”, which is especially noticeable when working with standard text (absolutely black letters on a bright white background). Because of this, the user quickly gets tired, general fatigue increases, and irreversible consequences for vision are possible in the future. Therefore, for everyday work not related to computer graphics, it is recommended to lower the contrast slightly. The picture will not be as rich as with the maximum value, but the strain on vision will be reduced. For viewing photographs and videos, amateur work with graphics programs and computer games contrast should be increased to the required level, focusing on high-quality reproduction the brightest areas of the picture: if you “sort out”, then the details in the highlights will disappear.

In addition, the contrast can be adjusted to the external lighting conditions, increasing during the day, especially in bright sun, and decreasing in the evening.

3. Colorful temperature. This term, familiar to amateur photographers, will also be found in the monitor settings menu.

In this case, this parameter sets the ratio of brightness of red, green and blue colors in the image on the monitor. It is measured in degrees Kelvin and is called temperature because it corresponds to the radiation spectrum of a completely black body heated to the appropriate temperature. The higher the color temperature, the cooler (paradox of perception) the hue of the image.

To a person, the colors of objects look the same regardless of the lighting, although in fact they change noticeably - this is clearly visible in photographs. When the lighting changes, the brain finds environment familiar objects and sets “white balance” based on them. At the same time, the colors of objects in which he is less “confident” (including on the monitor screen) are adjusted accordingly. This phenomenon is easy to check at home: paper sheets look white in the light of an incandescent lamp, but the document field in Microsoft Word has a bluish tint (unless, of course, the color rendering is shifted towards warm tones; in addition, the strength of this effect depends on the size of the screen - the brain “trusts” the color of a large object more strongly and begins to take it into account when setting its “white balance”).

By adjusting the color temperature of the display, the user can adjust the hue of the picture to the spectrum of background lighting - then the difference in perception will disappear. The menu of LCD monitors usually offers several options to choose from. fixed values color temperature. Smaller numbers give the image a warmer feel. pink tint, high values make the gamma colder, bluish. Standard color temperature values ​​correspond to several types of lighting: 2000K – household lamp incandescent, 3000K – fluorescent lamp with a “warm” phosphor, 4000K – fluorescent lamp with a “cool” phosphor, 5500K – bright daylight, 6500K – medium-brightness daylight (aka D65, is the standard value for most displays), from 7500K to 8100K – cloudy “weather” and 9300K – shadow. When changing the nature of the backlight, you must select the appropriate option on the display, but not all monitors have such wide range color temperature settings. In this regard, outdated CRT displays are more convenient: good models allow you to set any custom parameter value. On LCD monitors, for this you have to “conjure” with separate sliders for red, green and blue colors.

Using them, only a color correction specialist can set the correct color temperature.

Monitor software setup

The OSD menu allows you to only rough tuning display (although even such “processing with a file” in some cases will significantly increase the quality of the picture). You can more carefully adjust the image parameters using specialized programs. The principle of their operation is simple: specially selected images are displayed on the screen, and the user changes the parameters of the picture until it takes the form specified by the program instructions. The accuracy of display calibration using such applications directly depends on the visual acuity and meticulousness of the user.

In simple calibrator programs, settings are made using the monitor's on-screen menu. As a result, quickly changing settings is only possible if the monitor allows you to save user profiles. In addition, when you change the color intensity using the OSD menu, the brightness of the color will decrease proportionally in both light and dark areas. Moreover, if the corresponding gamma curve of the display has dips or “humps,” simple linear color compensation can only smooth them out, but not completely eliminate them.

More complex utilities require the user to " feedback» in the form of selecting certain items in test tasks, and “at the output” they record the so-called ICC profile of the monitor, which contains compensating gamma curves, which, when superimposed on the display curves, give uniform color rendition over the entire brightness range (of course, with strong errors, but this option is still better than simple linear compensation).

Most utilities for subjective monitor calibration are universal and allow you to adjust all image parameters in one pass. However, we recommend using two different programs to adjust the display: one is more suitable for adjusting brightness and contrast, the other is better at color correction.

4. Set the contrast control in the monitor OSD to maximum and the brightness control to minimum.

5. Increase the brightness until the background and everything are visible dark rectangles at the top of the scale. Now gradually reduce the brightness until only rectangles numbered 6 to 24 remain distinct, and the leftmost one, corresponding to a hue with an intensity of 1.2%, merges with the black background.

Remember that if you set the menu too high brightness, the monitor will not be able to display blacks correctly, and excessively low brightness will lead to loss of shades in dark parts of the image.

6. After adjusting the brightness, select the appropriate contrast for the ambient lighting conditions. As you decrease it, stop at the value at which large rectangles around the central scale will remain clear and will differ sharply from each other in intensity. You can control how the monitor displays the lightest shades close to white using the lower half of the central scale. It’s not scary if the rightmost rectangles with numbers 252 and 249 merge with the white background - this is how it should be if the contrast of the picture is normal.
