Reducing screen brightness on desktop PCs
The list of ways to reduce the screen brightness of external monitors is not as long as for laptops. In fact, there is only one method - using a special menu.
Monitor settings
There are special buttons on the monitor to control all the monitor settings. Their location depends on the device model and its manufacturer. They can often be found on the side or bottom. Much less often they are located on the back side. The list of actions to reduce brightness will look approximately as follows:
- Press the main "Menu" button on the monitor. Sometimes it is signed as "Enter".
- Next, using the buttons nearby on the device, go to the menu, which is responsible for setting up the picture. It can be called differently. Look for one that has the line “Brightness” or “Brightness”.
- Then simply use the same keys to change the value of the brightness bar. When finished, press the special button on the monitor that closes the entire menu. Again, it is called differently on different devices.
If you are unable to complete the necessary steps yourself, write your monitor model in the comments - we will definitely give more precise instructions on how to reduce brightness.
