Adjusting the brightness of your screen in laptop or tablet can be easily done in Windows. However, when you are using a desktop computer, then for adjusting the screen brightness level you have to physically operate the controls of your monitor. Therefore, many users ask whether it’s possible to adjust screen brightness of a desktop computer in Windows. The answer is, YES. In this tutorial, we will explain in detail how to adjust brightness in Windows for desktop computers.
First, learn what is DDC/CI Protocols
The Display Data Channel (DDC) / Command Interface (CI) protocols is a combination of protocols used for digital communication between a graphics adapter and a computer display. Almost every monitor today supports DDC/CI feature. By using this feature a monitor informs the computer about the display modes it supports and allows a user to alter monitor settings like contrast, brightness and color pallet from their computer.
Second, how you can use DDC/CI
First make sure that your monitor supports DDC/CI. If your monitor is 3 to 4 years old, then it will support this feature because DDC/CI is an integral feature of all modern day monitors and performs a very important task in their proper functioning. Also, by default DDC/CI feature is enabled in your monitor, but it’s better to verify this and enable it if it’s disabled.
For enabling DDC/CI you will have to press the Settings button on your monitor. Pressing the Settings button will open the menu of your monitor. Now, you surf through this menu to find DDC/CI feature and if it’s disabled, then enable it. In the above mentioned example, DDC/CI option is under the System menu, but it can differ based on the manufacturer and model of your monitor.

Once you have enabled the DDC/CI feature of your monitor then your main task is completed as your computer will now be able to send commands to your monitor. All that remains is installing a software, which can simplify the process of sending these command.
Although there are some manufacturers which provide software with their monitors that are capable of working with DDC/CI, but such software don’t work with other brand of monitors. Therefore, you should install a program on your computer which has been especially designed for this purpose.
