Monitors will not automatically turn off. I have set my monitors to turn off after 30mins of inactivity, and only the two monitors connected to the 8800GTX card does.

SOLVED: Windows 10 Sleeps After 1-4 Minutes of Inactivity. If the issue is with your Computer or a Laptop you should try using Reimage Plus which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. Sep 04, 2015  I recently updated from Window 8.1 to Windows 10. The upgrade went fairly well except for my laptop monitor turning off after 1 or 2 minutes of inactivity. I have changed all power settings to appropriate times. At times, normally after a fresh restart, my screen saver kicks in correctly.

Describes the best practices, location, values, management, and security considerations for the Interactive logon: Machine inactivity limit security policy setting.

Reference

Beginning with Windows Server 2012 and Windows 8, Windows detects user-input inactivity of a sign-in (logon) session by using the security policy setting Interactive logon: Machine inactivity limit. If the amount of inactive time exceeds the inactivity limit set by this policy, then the user’s session locks by invoking the screen saver (screen saver should be active on the destination machine). This policy setting allows you to control the locking time by using Group Policy.

Possible values

The automatic lock of the device is set in elapsed seconds of inactivity, which can range from zero (0) to 599,940 seconds (166.65 hours).

If Machine will be locked after is set to zero (0) or has no value (blank), the policy setting is disabled and a user sign-in session is never locked after any inactivity.

Best practices

Set the time for elapsed user-input inactivity based on the device’s usage and location requirements. For example, if the device or device is in a public area, you might want to have the device automatically lock after a short period of inactivity to prevent unauthorized access. However, if the device is used by an individual or group of trusted individuals, such as in a restricted manufacturing area, automatically locking the device might hinder productivity.

Policy management

This section describes features and tools that are available to help you manage this policy.

Restart requirement

Restart is required for changes to this policy to become effective when they are saved locally or distributed through Group Policy.

Group Policy

Because this policy setting was introduced in Windows Server 2012 and Windows 8, it can only be set locally on those computers that contain this policy setting, but it can be set and distributed through Group Policy to any computer running the Windows operating system that supports Group Policy.

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

Vulnerability

This policy setting helps you prevent unauthorized access to devices under your control when the currently signed-in user leaves without deliberately locking the desktop. In versions earlier than Windows Server 2012 and Windows 8, the desktop-locking mechanism was set on individual computers in Personalization in Control Panel.

Countermeasure

Set the time for elapsed user-input inactivity time by using the security policy setting Interactive logon: Machine inactivity limit based on the device’s usage and location requirements.

Potential impact

This security policy setting can limit unauthorized access to unsecured computers; however, that requirement must be balanced with the productivity requirements of the intended user.
