Many users, either on duty or for personal reasons, have to spend a lot of time at the computer. And not the last role in the comfort of work is played by the brightness and contrast of the image on the screen of a monitor or laptop. Oversaturation or poor lighting may make your eyes tired. Let's see how to make the necessary settings using a few simple tools.
How to change the brightness on Windows 7 (or any other system) on a desktop computer
First, consider the moment the system starts. The normal mode of image perception is usually associated with the user when the welcome screen appears on the monitor. It is only by his appearance that one can judge how comfortable he is perceived by the eyes. Immediately attract attention and brightness, and contrast. Changing one of the parameters on stationary computers can be completely elementary.
It's no secret that it is in desktop PCs or workstations that the system unit and monitor (or several) are used separately. Their design is such that directly on the front panel there are one or two buttons: increase or decrease brightness.
In addition, if, so to speak, in a question related to how to change the brightness of the screen or the contrast of what is displayed on the monitor, dig a little deeper, it is worth noting that any monitor has its own menu, called by a special button, in which there are extended settings, including the mode of shifting the image, stretching or narrowing it, etc. As you can see, personalization is quite simple.
How to adjust the screen brightness on a laptop
With laptops, this is even easier. Since the screen is an integral part of the entire structure, there are no special buttons on it, as provided for stand-alone monitors. Nevertheless, the question of how to change the brightness on Windows 7 or any other system (there is no fundamental difference) is solved using special keyboard shortcuts.
As a rule, the brightness parameter is changed using the Fn button in combination with either the function keys, on which there are up and down arrows and an image in the form of a sun. For example, in Fujitsu laptops, these are the keys F7 (increase brightness) and F6 (decrease), on others - F2 and F1, etc.
In some models, such settings can be made using the same pressed Fn key, using additional standard buttons with left / right arrows (sometimes up / down).
Adjust screen settings on any Windows system
Another simple method that allows you to solve the problem of how to change the brightness on Windows 7 is to right-click on an empty area of the Desktop and select the screen settings item (personalization) from the context menu.
After entering the section, all available parameters will be displayed, which will not be difficult to change at your discretion.
Setting parameters in the power supply circuit
These were, so to speak, the simplest methods. Now let's see how to adjust the screen brightness on Windows 7 using our own system tools. For this, it is necessary to use the power section, access to which is carried out from the standard Control Panel. Here you need to select the item for changing settings, after which two main plans (balanced and saving mode) will be shown.
If for some reason they do not suit the user, they can be easily changed. To do this, use the item for changing additional settings, where the adaptive brightness control mode is turned on . You can also change the brightness in the “Screen” section, where the settings are presented in the category of display off parameters.
Using a graphics card management program
How to change brightness on Windows 7 another way? You can use special utilities for managing graphics adapters NVIDIA and AMD, which are initially installed in the system.
After calling the control program either from the system tray, if it is in the active state, or from the same Control Panel, you need to find the display parameters section in it, and then go to the desktop color adjustment item (for NVIDIA, for example). It is here that you can change the brightness, and contrast, and gamma, and image saturation, and much more.
The simplest test for comfort
So, the screen settings are set. Now you need to check how comfortable the perception will be. To do this, open a blank Word document. If you feel uncomfortable looking at it, you should change the screen settings. You can simply take a blank sheet of A4 paper and compare it with the white margin of the document. If the difference is not felt when looking at the sheet and the screen, then everything is in order. Finally, do not forget that for prolonged work at a computer or laptop, no matter how optimal the settings are, every 45 minutes it is recommended to take a break for about a quarter of an hour to relieve fatigue, including from the eyes.
As for the settings, the methods are quite diverse, and which one to use is up to you. However, if it is only about brightness, the best option would be buttons and function keys. But if you need to fine-tune it, it is better to use the software of both the OS itself and the programs that are part of the control software of the graphics cards, especially since they are designed for that.
