There are many situations when we need to keep our computer running without using monitor. It usually happens when we are downloading any large file or when we are leaving our computer for a short while. In such a case, most of us leave our computer monitor turned ON even though it is not required until the power saving system automatically turns it off after some time. Monitor consumes a significant amount of power. So, turning it off when not in use will save power.


You might be thinking "why not use the button provided to turn off our monitor?"
Yes, you can do that way but not always. It can cause wear and tear and the button may get damaged sometimes as it has happened to me now (esp if you had an old monitor). Also, this button is not provided for most laptops these days. In this article I will tell you an easy solution to turn Off your monitor on Linux.
