Brightness is the most important detail when working on your own computer. It is she who has a strong influence on eye fatigue. Weak brightness makes them quickly tired, due to the constant tension of vision. For this reason, there are constant difficulties how to change its indicator. There are also situations when the brightness on the laptop does not fully work. We will try to consider all kinds of options, how to deal with brightness on a personal laptop.
Power Settings
The first way to change the brightness is to go to Power Options. For a laptop on Windows 7, go to "Start", then find "Control Panel", and at the end click on the "Power" section.
An alternative is to go to the “Start” and use the search line to find “Power”. After finding you need to click on the corresponding button.
After you have switched to "Power Options", you need to find the "Screen Brightness" section. This section will help the user to adjust the brightness and contrast on the computer to the desired limits.
In case it is inactive, you need to try updating the driver of the monitor itself. Inactivity may also be a sign that the manufacturer has saved on such a function. Therefore, you will have to use other options for adjusting the brightness on the computer.
Time setting
Most users like to save laptop energy to work longer. To do this, you must configure the power supply. We find through the "Start" section "Power", click on "Setting the power plan." In the window that opens, you can select various options. For example, you can darken the laptop screen when working on battery power rather than on the network, or after a certain time put the computer into sleep mode.
This setting will help to save more battery power, increase the performance of the computer and the battery itself, and also help increase the screen brightness on the laptop.
Function keys
Most modern laptops have special keys that help you adjust the brightness of the monitor. You need to look at the top keys of category F (F1–12). The key should show the sun, and next to the sun + or -. Plus is needed to increase the brightness of the screen on a laptop, and minus to decrease the brightness.
If the laptop does not have such keys, you can use a certain combination, namely Fn + arrow to the right or left. The Fn key is located next to the Windows button. You need to hold Fn, and then click on the arrows. Pressing will decrease the brightness or increase the brightness.
This method has an unpleasant feature - the former brightness may return after some time. The best option would be to change it using Power Options.
Firmware in a laptop
Advanced laptops have unique capabilities that change brightness and contrast. For example, automatically changing and increasing the brightness of the screen on a laptop, under certain lighting conditions. In bright indoor conditions, the brightness will automatically increase. Such a feature is, for example, Sony Vaio.
To configure such a function, you need to go to the "Control Center", then click on the "Display" section and select "Automatic brightness settings." In a new window, you can set automatic adjustment or completely remove it to independently change the brightness. Also, at the end of the procedure, do not forget to click the "OK" button to save the changes that were made.
For other laptops, you need to find out about these settings in the instructions that are attached to the device or find on the Internet all the necessary information.
Other programs
You can increase the brightness of the screen on the laptop with the help of other programs. In addition to the built-in, there are special ones that can be easily downloaded from the Internet. In addition to brightness, such programs can change the contrast, screen resolution of the laptop monitor, as well as the color scheme and other parameters.
The most popular programs are: Display-Tuner and iBrightness Tray.
It is enough to find the program data, download from the Internet and start using it in business. There is nothing complicated in their application.
Difficulties and their solutions
After the user has changed the brightness of the laptop monitor, you need to make sure that the system saved the changes. Keep in mind that most laptops automatically save these settings. However, if, for example, after rebooting the system, the settings were not saved, you need to go to the power settings and carefully check the settings. There is a high probability that the user himself set the values incorrectly.
If, after the steps taken, the brightness continues to change independently, you need to make sure that the automatic adjustment is disabled. To do this, go to additional power settings and turn off adaptive brightness control. After making the changes you need to remember to click the "OK" button.
A secondary problem with increasing screen brightness on a laptop is video drivers. Often, difficulties with brightness are caused by their recent update. To solve these problems, you must perform the following steps:
- Open device manager.
- Find the “monitor” section and open it.
- Delete all kinds of displayed monitors.
- Update the configuration of the equipment itself to detect the monitor, and install the appropriate driver on it.
It is also recommended that you download the latest drivers for your video card. If the problems are associated with the latest version of the drivers, you should install the previous version or the version that was previously installed on the computer. This will help the user to decrease or increase the screen brightness on the laptop.
