There are several ways to turn off your monitor without putting it to sleep. If you're using a Windows 7 laptop, you can go to Control Panel > Power Options and change the setting for Choose what closing the lid does to Do Nothing. This will prevent your computer from going to sleep when you shut the lid. For Windows 10, you can set the screen off display time in the power settings or use the DisplayPowerOff utility. Additionally, you can simply press the power button on your monitor to turn it off without putting your system to sleep. However, be aware that some methods may not work for all types of displays, such as OLED screens.

Use the DisplayPowerOff utility
The DisplayPowerOff utility is a simple and lightweight tool that allows you to turn off your monitor on command without putting your system to sleep. It is designed to work with Windows API and can be used for PCs, notebooks, or netbooks with a monitor.
To use the DisplayPowerOff utility, you can download it from SourceForge.net. Once downloaded, simply run the program, and your monitor will be turned off while your system remains on. This can be useful when you want to conserve battery power or when you want to temporarily power off your display without interrupting any ongoing processes or downloads.
The DisplayPowerOff utility offers some additional features as well. It can be set as a screensaver, and it also has the option to lock your workstation when the display is turned off, providing a layer of security. Additionally, it can be launched as a system tray icon application, giving you quick access to the utility whenever needed.
One notable aspect of this utility is its ease of use and configurability. It does not require any installation or additional frameworks, and it can be easily accessed from the system notification area icon. Furthermore, it does not run in the background, ensuring that it only operates when you actively use it.
Overall, the DisplayPowerOff utility is a straightforward and effective solution for users who want to turn off their monitors without putting their systems into sleep mode.

Use the SendMessage method
The SendMessage method can be used to turn off your monitor without putting your computer to sleep. This method involves using a specific code to send a message to the monitor, instructing it to turn off.
One way to use the SendMessage method is through a PowerShell script. The following code can be used:
Powershell (Add-Type ' [DllImport("user32.dll")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)
This code includes the necessary DllImport statement and defines the SendMessage function with the required parameters. The `-1` value for the first parameter of the SendMessage function indicates that the message will be sent to all windows. The `0x0112` value for the second parameter represents the WM_SYSCOMMAND message, which is used to perform system-wide actions. The `0xF170` value for the third parameter is the SC_MONITORPOWER constant, which specifically targets the monitor's power. Finally, the `2` value for the fourth parameter indicates that the action to be performed is to turn off the monitor.
Another way to use the SendMessage method is through an AutoHotkey script:
#m:: Sleep 1000 SendMessage, 0x112, 0xF170, 2,, Program Manager return
In this script, the `#m::` part defines a hotkey that can be used to trigger the script. The `Sleep 1000` part introduces a delay of 1 second before executing the `SendMessage` command. This delay allows the user to release any keys that might wake up the monitor. The `0x112, 0xF170, 2` parameters are similar to those in the PowerShell script, targeting the monitor's power and instructing it to turn off. The additional `, Program Manager` part specifies the target window for the message.
It is important to note that the effectiveness of these methods may vary depending on your specific system configuration and operating system version. Some users have reported that these methods worked on Windows 7 but not on Windows 10. Additionally, with the introduction of Modern Standby in Windows 11, the behavior of the SendMessage method may have changed, causing the entire system to enter sleep mode instead of just turning off the monitor.
