When using the desktop flavor of Raspberry Pi OS, you will notice that the screen will be automatically put to sleep after a certain amount of time of inactivity.
A part of how the Raspberry Pi achieves this is to blank the video device connected to your screen. Basically, by blanking the output, the display will stop receiving video output and typically put itself to sleep.
We will show you how you can easily disable the screen blanking behavior using both the desktop and command-line interface within the next few steps.
