With the advent of modern liquid crystal monitors (TFT, LCD, LCD), the issue of the correct setting of their parameters has become particularly relevant. It is hardly known to a beginner who first started working with such a monitor that if in obsolete models based on a ray tube (CRT) no program was needed to adjust the brightness of the monitor, now the situation has changed radically. You can talk about the advantages of the new technology for a very long time, and now there is so much such information that even every schoolchild is aware of the absence of flicker of the personnel scan, low weight and compact dimensions of LCD monitors. It would seem that the ideal device for displaying graphic information has finally been developed. But, alas, users who happened to change their usual CRT monitor to a modern LCD know very well how the first time after such a change your eyes hurt and watery during operation. Subsequently, these symptoms disappear, but their very appearance indicates incorrect settings: the brightness of the monitor and the contrast must be necessarily adjusted.
A properly configured LCD monitor is able to more accurately transmit the color gamut of the image, which is simply necessary for popular TN matrices, as well as reduce the load on vision. Before adjusting the brightness of the monitor, you should set the appropriate color profile for it, which can be downloaded from the manufacturer’s website. After that, you can proceed with the adjustment.
The simplest program for adjusting the brightness of the monitor, which is always "at hand" is the video adapter driver. Any video card allows you to control many basic display options. For example, to take advantage of the ability to adjust the monitor brightness, right-click on the desktop and start the Catalyst control center from the menu that appears (by the way, it only works if NET.Framework is installed on the system). Here in the left part of the window you need to select the desktop control item. By allowing the use of color controls, we get the opportunity to change the brightness of the monitor. If you need to adjust not only the desktop image, but also the video, then go to the corresponding item (Video), where we adjust the brightness. All these features are also present in the NVidia card driver settings.
Despite the convenience of making settings using the capabilities of the video adapter driver, sometimes preference is given to third-party programs. There are quite a lot of them: from the simplest, in which the brightness is adjusted by entering a value in percentage terms, to semi-automatic combines that independently adjust the brightness depending on the time of day. For example, even a person without preparation can understand Monitor Bright. More flexible tuning is possible in Display Tuner, MagicTune and NaViSet.
In addition to software solutions, one should not forget about the capabilities of the monitor itself. Many of them allow you to change the modes preset by the manufacturer by pressing a single button: for watching a movie there is a “Movie” mode, for working on the Internet - “Internet”, etc. Usually it turns out to be much more convenient for adjustments by the driver and, especially, third-party programs. After all, you can “forget” to install the setup program with a clear conscience, and change the modes using the button on the monitor panel. It's all about user preferences.
Owners of laptops are in a better position, because they can adjust the brightness of the screen glow with just two buttons on the keyboard. Usually this is a combination of two buttons - “Fn” and with the corresponding sun icon (left-right keys).
