How to Change Turn Off Display After Time in Windows 10
In Windows 10, you can specify for how long your computer remains inactive before the connected monitor is automatically turned off. If you have not changed the default power management settings, the display will be turned off after 10 minutes. Here is how to change these settings.
Since Windows 8, Microsoft has added a Lock Screen feature to Windows in addition to the Logon screen where you type the password. In Windows 10 also, the Lock Screen is an additional screen which is displayed with a fancy background and some useful information like clock and date. It appears before you can pick a user account to sign in. When you lock your computer, again you will see the Lock screen. When the PC is locked, the normal display off timeout value has no effect on it and you cannot specify the timeout value after which the screen will turn off while you are on the Lock screen. Turns out, there is a hidden registry setting for this and enabling it even turns it on in the Power Options control panel GUI - the same window where you specify other power related timeouts. Let me show you how.
