How to turn off your screen on Windows

  1. Extract the ZIP and open ScreenOff.exe.
  2. Select the monitor you want to control.
  3. Click the power button or press Alt + Space.

A two-second countdown gives you time to cancel with Escape or the shortcut again. Press Alt + Space after power-off to request a wake command.

Good to know.

Shortcuts, display setup, and answers before you buy.

What is the screen-off shortcut key?

While ScreenOFF is running, press Alt + Space to turn off the selected monitor after a two-second countdown. Press the shortcut again during the countdown, or press Escape, to cancel. ScreenOFF uses this combination globally, replacing the usual Windows window-menu shortcut until you exit the app.

Can I turn off one monitor without putting the PC to sleep?

Yes. Select the monitor in ScreenOFF, then click its power button or use Alt + Space. The app sends a DDC/CI power command to that display; it does not request Windows sleep or shutdown. Your ordinary Windows sleep settings still apply.

How do I turn the screen back on?

Press Alt + Space again to request a wake command for the selected display. Wake behavior depends on the monitor. If it stops accepting DDC/CI commands while off, use its physical power button. Mouse movement or typing may not wake a display powered off this way.

Does it work with multiple monitors or laptop screens?

You can choose an individual supported external display in a multi-monitor setup. DDC/CI support must be enabled in the monitor settings. Built-in laptop panels typically do not expose the external-monitor DDC/CI power controls this app needs.

Is screen off the same as locking Windows?

Turning a monitor off controls its display power. It does not lock your Windows account. Use Windows + L when you want to lock your PC.

Do I need an installer, subscription, or activation key?

No installer or activation key is required. ScreenOFF is a portable Windows app delivered as a ZIP. Pay USD 3.99 once through PayPal, download it after payment, and keep your copy. It does not start automatically with Windows.

How do I identify which physical screen I’m controlling?

Open the display dropdown. ScreenOFF shows name badges on connected displays not marked off, with a white border on the selected display. Close the dropdown or switch apps to dismiss the badges. The screen-off shortcut pauses while you configure screens.

Can I rename and reorder my monitors?

Double-click a display name, or press F2, to rename it. Drag its grip to change its order, or use Control + Up/Down. Enter saves a name; Escape cancels the edit. A blank name restores the default.

Does ScreenOFF remember my display setup?

Names, ordering, and selection save automatically on your PC. Saved entries remain when a monitor disconnects. Moving a display to a different port or adapter can give it a new Windows identity. These preferences do not change your Windows display arrangement.

How do I refresh the list after connecting a monitor?

Use Rescan screens after reconnecting a display or enabling DDC/CI. It refreshes monitor connections, keeps your selection when possible, and cancels any pending countdown without sending power commands.

Why is my monitor unavailable?

Individual monitor power control needs DDC/CI support from the monitor and the connection. Enable DDC/CI in the monitor’s own menu, then rescan. Some cables, adapters, docks, and built-in panels do not expose the required controls. ScreenOFF does not fall back to turning off every screen.

Why doesn’t moving the mouse turn the monitor back on?

A DDC/CI power command can behave differently from a Windows display timeout. Use Alt + Space to request a wake command. Some monitors stop listening while off and need their physical power button.

Can I use ScreenOFF while a download or another task runs?

ScreenOFF sends a power command to the selected monitor; it does not close your apps or request PC sleep. Tasks continue as allowed by Windows and the apps themselves. Your existing system sleep settings still apply.

Does it turn off every monitor at once?

ScreenOFF controls the selected supported monitor. Choose another display when you want to control it. It does not silently switch to an all-screens-off command when individual control is unavailable.

What happens when I close the app window?

Closing or minimizing the window hides ScreenOFF in the system tray. The global shortcut remains available. Open ScreenOff.exe again to restore the existing window. Right-click its tray icon to exit completely.

What if Alt + Space is already in use?

The shortcut can be unavailable if another app has registered it. Use ScreenOFF’s power button instead. While ScreenOFF owns the shortcut, the usual Windows window-menu action is replaced; exiting restores that behavior.

Does the OFF label measure the monitor’s live power state?

The label reflects the last successful power command, not a live power measurement. Command history is not restored as monitor state when the app restarts.

Is ScreenOFF a screen dimmer or a black-screen overlay?

ScreenOFF sends a supported monitor power command through DDC/CI. It does not place a black window over your desktop or change screen brightness. The colored monitors on this website are an interactive demonstration.

Will it save electricity or prevent OLED burn-in?

Powering down an unused display can reduce its active use, but the result depends on the monitor and its supported power mode. ScreenOFF does not promise a specific energy saving or burn-in prevention. Follow the display manufacturer’s care guidance.

How do I get my download after paying?

Pay USD 3.99 through PayPal, then download the ZIP from the checkout. Extract it and open ScreenOff.exe. Keep a backup of the ZIP. The purchase link is available for seven days; there is no activation step.

Requires a DDC/CI-compatible external monitor. Wake behavior varies by display.
