Use 'Display power Off Utility' to power off your monitor without turning off your system
There are several ways to power off your monitor without turning off your system. One way is to adjust your power settings. This can be done by going to your power settings and selecting "When plugged in, turn off my screen after" and choosing a time interval, such as 5 minutes or "never". Alternatively, you can use a third-party utility like NirCmd or Dekisoft Monitor Off Utility to manually turn off your monitor without affecting your system.
If you are using a Linux operating system, you can use the ddcutil command-line utility to control your monitor settings. The Monitor Control Command Set (MCCS) specifies a set of Virtual Control Panel (VCP) features, including the ability to turn off the display.
Another option is to use a hotkey approach, which allows you to manually trigger your monitor to turn off. This can be done through third-party software, such as AutoHotkey, which lets you press a key combination like ⊞ Win+M to sleep the monitor.
Turning off your monitor can help conserve energy, reduce eye strain, and save power, although the amount of power saved may not be significant. It is important to note that while your computer is running, it will still consume power, and the hardware and software used will impact the overall power usage.

For a PC, go to Control Panel, System and Security, Power Option, Change Plan Settings
If you're using a Windows PC and want to close your laptop while keeping it connected to an external monitor, you can adjust your power settings to prevent the system from going to sleep. Here's a detailed guide on how to do it:
For a PC, go to Control Panel, System and Security, Power Options, Change Plan Settings:
- Access the Control Panel: Open the Start menu and search for "Control Panel." Click on the corresponding result to launch it. Alternatively, you can press the Windows key + R on your keyboard to open the Run dialog box, then type "control panel" and press Enter.
- Navigate to Power Options: Once you're in the Control Panel, locate and click on "Hardware and Sound." From the options that appear on the left-hand side of the screen, select "Power Options."
- Change Plan Settings: On the Power Options screen, you'll find various settings related to your computer's power management. Look for the option "Choose what closing the lid does" and click on it. This will open a new window where you can customize the actions triggered when you close your laptop lid.
- Configure 'When I close the lid' settings: In the new window, you'll see options for the power and sleep buttons, as well as lid settings. Under the "When I close the lid" section, you can specify different actions for both battery and plugged-in power sources. To keep your laptop from going to sleep when you close the lid, select "Do nothing" for both options.
- Save your changes: Before closing the window, make sure to save your new settings. Now, when you close your laptop lid while it's connected to an external monitor, your system will remain active, and you can continue using the external display without interruption.
Remember, these steps are specifically for Windows PCs. If you're using a different operating system, such as Linux Ubuntu, the process might vary, but the underlying goal of keeping your system active while using an external monitor remains the same.

For a laptop, set the option choose what closing the lid does to nothing
If you want to close your laptop's monitor without sending it to sleep, you can do so by adjusting your power settings. This is especially useful if you want to use your laptop with an external monitor, freeing up desk space and allowing you to work more comfortably.
For Windows laptops, the default setting is to enter sleep mode when the lid is closed. To change this, open the Control Panel and navigate to Hardware and Sound > Power Options. Click on "Choose what closing the lid does" in the left pane. You will see options for "When I close the lid" under "On battery" and "Plugged in". Set both of these to "Do nothing". This will prevent your laptop from going to sleep when you close the lid, allowing you to continue using it with an external monitor. Remember to save your changes before closing the window.
If you're using a MacBook, there is no need to change your lid settings. However, you must ensure that your device is plugged into a power source before closing the lid, or it will automatically sleep. Newer MacBook models have a built-in setting that automatically detects when you plug into an external display and stays awake. If you want to manually adjust your settings, go to System Settings > Battery and choose the Power Adapter tab on the sidebar. Enable the option to "Prevent the computer from sleeping automatically when the display is off". This will keep your MacBook active and ready to use even when the lid is closed.
Once you've adjusted your laptop's settings, you can connect your external monitor to the correct display output port on your laptop or a connected USB hub or dock. Close the lid of your laptop and adjust any display settings as needed. Now you can use your laptop with the lid closed, enjoying the benefits of a larger screen and a more comfortable setup.

Use the SendMessage powershell script with the parameters -1,0x0112,0xF170,2 to turn off the display
If you want to turn off your computer screen without putting it to sleep, there are a few methods you can try. One method is to simply press the power button on your monitor to turn it off. However, if you want a more advanced solution, you can use the SendMessage PowerShell script.
The SendMessage function in PowerShell can be used to send the Windows API command to change the power state of the display. The specific parameters you need to use for the SendMessage command are: -1 for hWnd, which means broadcasting the message to all windows; 0x0112 for Msg, which corresponds to WM_SYSCOMMAND; 0xF170 for wParam, which corresponds to SC_MONITORPOWER; and 2 for lParam, which turns off the monitor.
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)
By running this script, you can turn off your display while keeping your computer on. This can be useful in various scenarios, such as when you want to conserve energy or locate a specific computer by blinking the monitor.
It is important to note that running unknown scripts can be risky, and it is always recommended to test them in a safe environment first. Additionally, some users have reported issues with the SendMessage function causing a script to hang, so it is advised to be cautious and test thoroughly before implementing this solution.

Change the Console lock display off timeout attribute to 2 in Power Options by enabling it with a registry edit
If you want to change the Console lock display off timeout attribute to 2 in Power Options, you will need to enable it with a registry edit. This will only affect the lock screen that is displayed when a user locks the computer (Win+L). The Console lock display off timeout setting is set to 1 minute by default for all power plans.
To enable the lock screen display timeout setting in Power Options, you will need to follow these steps:
- Sign in as an administrator: This is necessary to be able to add or remove the setting in Power Options.
- Find the registry key: The registry key for the "Console lock display off timeout" setting is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7.
- Change the Attributes data: You will need to change the Attributes data to 2. This will enable the "Console lock display off timeout" setting in the Power Options.
- Exit the Registry Editor: After making the changes, exit the Registry Editor.
- Launch Powercfg.cpl: This will open the Power Options Control Panel applet.
- Click on "Change Power Settings": In the Power Options Control Panel, click on the "Change Power Settings" link next to your current power plan.
- Increase the lock screen display off timeout: You can now increase the lock screen display off timeout to your desired value, making sure it is less than the "Turn off Display after" setting.
It is important to note that any changes made to the Console lock display off timeout setting will affect all users on the PC that use the same power plan. Additionally, this method has been tested to work on Windows 8, 10, and 11.
