Update Your Display Adapter Driver

Outdated, incompatible or corrupted drivers are usually the cause of Windows 10 screen brightness control problems. A device driver is software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly, if at all. We recommend that you update the display driver first and see if this solves the problem. To do this, open Device Manager by right-clicking the Start button and selecting the 'Device Manager' result from the contextual menu or type 'device manager' in Search and click the 'Device Manager' result.

In Device Manager, find 'Display adapters', expand it, right-click the display adapter and select 'Update driver' from the drop-down menu.

You will be asked if you want to search for updated driver software automatically or to browse the computer for driver software. If you select the first option, Windows will search your computer and the Internet for the latest driver software for your device. If you select the second option, you must locate and install the drivers manually. Using this option requires having previously downloaded the driver on your computer or USB flash drive.

Another way to update or install new drivers for devices is to do it by using third-party software such as Snappy Driver Installer. You will need a computer with a working internet connection to download it.

Snappy Driver Installer (SDI) is a powerful free driver updater tool for Windows that can store its entire collection of drivers offline. Having offline drivers gives Snappy Driver Installer the ability to have access to fast driver updates, even if there is no active Internet connection on your computer. Snappy Driver works with both 32-bit and 64-bit versions of Windows 10, Windows 8, Windows 7, Windows Vista, and also works with Windows XP. Drivers are downloaded through Snappy Driver Installer in 'driverpacks', which are simply collections (packs) of drivers for various hardware such as sound devices, video cards, network adapters, etc. It can also show duplicate drivers and invalid drivers. It separates the updates that require you to restart your computer so that they are easier to distinguish. You can download Snappy Driver Installer from here.
