How to adjust brightness on a laptop?
On almost any laptop adjusting screen brightness is quite simple. There are special keyboard shortcuts for this.
Press the "Fn" and "Left Arrow" or "Fn" and "Right Arrow" keys (you may have other brightness keys. Look for the "sun" icon on the keys) to adjust the desired monitor brightness level.
Fn key in combination with the top row or arrow keys can perform a specific action that is often written on the keys themselves. If these combinations do not work on your laptop, this most likely means that the laptop is missing drivers ( software), allowing you to use hotkeys. If there is such a problem, look at the very bottom “Method 2”.
How to adjust brightness on a desktop computer?
The easiest way is to use the buttons on the monitor itself to go to the menu and adjust the brightness there. If for some reason you cannot adjust the brightness using hardware, there are two more ways.
Method 1. Go to your computer's video driver settings. You can almost always find it near the clock in the " tab Hidden icons". Next, in the driver itself, you need to find "Adjusting color parameters" (yours may be a little different) and there, moving the sliders, achieve the desired brightness level.

When downloading the driver, make sure that you select it correctly: the video card software must match the version and bitness of the system.
After updating the driver, the problem with the inability to change the display brightness should be resolved. If the problem persists, then most likely there is physical damage matrix or cable, which is corrected by replacing the failed part.
