Hello.
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 unless you turn up the brightness. As a result, if the brightness of the monitor is low, 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, let's look at each of them.
Important point! The brightness of a laptop screen greatly affects the amount of energy consumed. If your laptop is running on a battery, then turning up the brightness will drain the battery a little faster.

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

One small note. These buttons do not always work; the reasons for this are most often:
- uninstalled drivers (for example, if you installed Windows 7, 8, 10, then by default 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!) . Article on how to update drivers in auto mode: https://pcpro100.info/obnovleniya-drayverov/
- these keys can be disabled in the BIOS (though not all devices support this option, but it is possible). To enable them, enter the BIOS and change the corresponding 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 brightness settings through the Windows Control Panel (the recommendations below are relevant for Windows 7, 8, 10).
1. First you need to go to the control panel and open the “Hardware and Sound” section (as in Fig. 2). Next, open the “Power Options” section.

In the power section at the very bottom of the window there will be a “slider” for adjusting the brightness of the monitor. By moving it to the desired side, the monitor will change its brightness (in real time). You can also change the brightness settings by clicking on the link “Setting the power supply scheme”.

3) Adjusting brightness and contrast settings in drivers
You can adjust brightness, saturation, contrast and other parameters in the settings of your video card drivers (if, of course, they were installed
