In Windows 7 and Windows 10 you can improve the display quality of the PC screen with a calibration wizard, which allows you to improve the colors and contrast by optimizing them according to your perception. This procedure works on any monitor used, be it the laptop screen or a new external monitor. READ ALSO: How to change screen brightness on PC, even automatically
To understand what the wizard does to calibrate the monitor you need to have an idea on some concepts.
First of all, when we talk about Gamma we mean the coding of the images seen by electronic devices. Our eyes see things differently than computers and use "gamma coding" to make images clearly visible to the human eye. The monitors perform a gamma correction so that what we see on the screen resembles what we would like to see in the real world. The pixels on the monitor are three colors, red, green and blue (RGB) and the mixture of these colors make the colors we see. By adjusting the Gamma coding, you can adjust the monitor so that it represents all the colors well.
The color balance, then, is an adjustment of the way the various intensities of colors are displayed on the monitor. It is therefore important that the color balance is balanced and correct to prevent one from predominating over the others.
Knowing this, you can start calibrating the screen in Windows .
To start, in Windows 10 and Windows 7 or 8.1, search for monitor calibration from the search box or from the Control Panel, in the Appearance and Personalization -> Screen section, by clicking on Perform color calibration . To use this program you must also authorize the execution of the Windows User Account Control. Go to Next to continue and read the next message, where you are asked to press the menu button on the monitor and restore, if they had been changed, the factory display settings to start from scratch. On a laptop this button may not be present.
Press Next again and read the explanation on the Gamma configuration which helps to recognize the optimal setting.
Here you have to memorize the figure with your eyes because you can't go back afterwards. Press Next to continue and, in the following screen, move the vertical cursor to adjust the range until the colors are identical or almost to the example in the previous screen, so that the dots in the center of the circles are not seen. Having the gamma set correctly is vital for subsequent settings so it is better not to make mistakes and, if in doubt, to cancel and start again.
Go Next again when finished and set the contrast and brightness (don't press Skip at this point and go Next).
Also for brightness and contrast it is necessary to see the example and then adjust the sliders to make them look as similar as possible to the figure.
To adjust the brightness and contrast, however, use the buttons on the monitor. For each monitor the controls can be different so it is better to read the instruction booklet. For brightness, you need to distinguish, in the photo, the jacket from the shirt and make sure that the X is barely visible. Most likely the brightness of the monitor will be lowered. The contrast must be as high as possible, but in the photo the folds of the shirt must be visible.
The next step is to adjust the color balance and it is a software adjustment with the RGB cursors to be adjusted with the mouse. Here, too, read the instructions and go ahead trying to achieve a neutral shade of gray.
With the color balance, the guided procedure ends and you can compare the previous calibration and the one just configured to see which one is better.
At the bottom of the last screen you are asked to activate ClearType to improve the display of text and characters on the LCD monitor.
To finish, to refine the calibration or to improve it, I had previously talked about programs and applications to adjust colors, contrast and brightness on the screen
