The brightness of the monitor screen is one of the most important details when working at a computer, which affects eye fatigue. The fact is that on a sunny day, usually, the picture on the monitor is faded and it is difficult to distinguish it if you do not add brightness. As a result, if the brightness of the monitor is weak, then you have to strain your eyesight and your eyes quickly get tired (which is not good.).
In this article I want to focus on adjusting the brightness of a laptop monitor. This can be done in several ways, we will consider each of them.
An important point! The brightness of the laptop screen greatly affects the amount of energy consumed. If your laptop is running on battery power, then adding brightness, the battery will drain a little faster.

How to increase the brightness of the laptop screen
1) Function keys
The easiest and fastest way to change the brightness of a monitor is to use the function keys on the keyboard. As a rule, you need to hold down the function button Fn arrow (or the range F1-F12, depending on which button the brightness icon is drawn on. “sun”, see Fig. 1).

One small remark. These buttons do not always work, the reasons for this are most often:
- drivers that are not installed (for example, if you installed Windows 7, 8, 10, then by default the drivers are installed on almost all devices that will be recognized by the OS. But these drivers work “wrong”, including often the function keys do not work!). An article on how to update drivers in auto mode: https://pcpro100.info/obnovleniya-drayverov/
- these keys can be disabled in the BIOS (although not all devices support this option, but this is possible). To enable them, enter the BIOS and change the appropriate parameters (article on how to enter the BIOS: https://pcpro100.info/kak-voyti-v-bios-klavishi-vhoda/).
2) Windows Control Panel
You can also change the brightness settings through the Windows control panel (the recommendations below are relevant for Windows 7, 8, 10).
1. First, go to the control panel and open the “Hardware and Sound” section (as in Figure 2). Next, open the “Power” section.
Fig. 2. Equipment and sound.
In the power section, at the very bottom of the window there will be a “slider” for adjusting the brightness of the monitor. Moving it to the desired side. the monitor will change its brightness (in real time). Also, the brightness settings can be changed by clicking on the link “Configuring the power scheme”.

3) Setting the brightness and contrast in the drivers
You can adjust the brightness, saturation, contrast and other parameters in the settings of your card drivers (if, of course, they were installed # 128578; )
Most often, the desired icon to enter their settings is located next to the clock (in the lower right corner, as in Fig. 4). Just open them and go to the display settings.

By the way, there is another way to enter the settings of graphic characteristics. Just click anywhere on the Windows desktop with the right mouse button and in the context menu that appears, there will be a link to the parameters you are looking for (as in Figure 5). By the way, no matter what your graphics card is: ATI, NVidia or Intel.
By the way, if you do not have such a link, you may not have drivers installed on your card. I recommend checking the availability of drivers for all devices with a few clicks of the mouse: https://pcpro100.info/obnovleniya-drayverov/

Actually, in the color settings you can easily and quickly change the necessary parameters: gamma, contrast, brightness, saturation, correct the necessary colors, etc. (see fig. 6).

That’s all for me. Good luck and quickly change the “problem” parameters. Good luck # 128578;
