Reasons Your Monitor Keeps Going To Sleep

Excellent performance for a long time is one of the features of high-quality systems with monitors. Nonetheless, you may sometimes experience the issue of a monitor that keeps going to sleep.

How will you feel if your screen suddenly goes blank, perhaps in the middle of working on something important? You may feel terrified of losing data. It is a problem common with systems with Windows 10 or Windows 7.

One of the most common causes of why your monitor keeps going to sleep is your system’s power settings. You may face this problem sometimes if your system’s sleep mode duration is very short. For instance, you are likely to see your monitor going to sleep persistently if you set it to 2 minutes. You may want to change the settings to a longer time to stop this from happening. 

Another common cause is the function of the screen saver. Every version of the Windows operating system has screen saver functionality. Your monitor may go to sleep mode when idle if you enable the screen saver and put the sleep mode in a specific short duration.
