Screen Blackout for Windows

Black out or dim one monitor, hide the taskbar on your OLED monitor or turn every screen off with a Stream Deck key on Windows, plus a shutdown timer and sleep timer that count down on the key. For OLED owners worried about burn-in, one press hides the taskbar or blacks out a screen. Blackout Monitor covers the monitor you choose with black: a privacy screen for a second monitor, a dark side screen while you game, or a screensaver for one monitor that goes black by itself when idle. The monitor stays powered, so the picture comes back with a press or a double-click. On Stream Deck +, a dial sets the darkness or the timer.

Features

Black out one monitor: pick it by name, or all but the main one. Press again, hold or double-click to bring it back

Keep playing: the black window is built to leave the keyboard focus with your game and stays out of Alt+Tab. It returns on top when you switch windows

Darkness: 100% black, or 90% to 30% to dim a screen and still see it

Auto blackout: a monitor left alone for 1 minute to 1 hour goes fully black and comes back when the mouse moves onto it. It can wait while full-screen games or videos play (on by default)

Stream Deck + dials: turn for darkness or minutes (also while the timer runs), push to start or stop; the touch strip shows the state

Hide Taskbar: Windows' auto-hide on or off, so the taskbar hides until you point at the screen edge; desktop icons optional. The key shows SHOWN or HIDDEN as Windows has it (a change in Windows Settings shows at the next press)

Screens Off: every monitor off with one press, optionally locking the PC first

Sleep Timer (shutdown timer): each press adds time, or one press starts a fixed time. The key shows the time left and blinks in the last minute. Hold to cancel. At zero: sleep, hibernate, shut down, screens off or lock

Questions

How do I hide the taskbar on an OLED monitor with Stream Deck? Press Hide Taskbar; press again to bring it back.

Can a Stream Deck button turn off my screen? Yes. Screens Off turns every monitor off; Blackout Monitor just the one you choose.

Can Stream Deck shut down my PC after an hour? Yes. Set Sleep Timer's At zero to Shut down and start a fixed time of 1 hour.

Does it prevent OLED burn-in? It reduces still images (black on an unused monitor, a hidden taskbar); how much that helps depends on the monitor.

Limitations

On a covered monitor, a game in exclusive full screen, the mouse pointer and Windows pop-ups can still show. An always-on-top window that opens without becoming active can show until you switch windows

Auto blackout counts a monitor as used while the pointer or the active window is on it: for a windowed video there, use full screen or turn auto blackout off

Blackout Monitor leaves one screen visible, so a single-monitor PC cannot black out or dim it (use Screens Off)

Auto blackout and the timer run only while their key is shown (another page or profile ends them)

Sleep or a restart cancels the timer; it never runs late

Hide Taskbar changes a Windows setting, which stays after the app closes; some managed PCs refuse the change (the key says so)

An app flashing in the taskbar for attention can keep the hidden taskbar shown until you open that app

Sleep needs classic sleep (S3); on Modern Standby PCs, choose another action

Some company PCs block PowerShell; the plugin cannot run there

Privacy

Everything stays on your PC: no account, no network, no telemetry. Auto blackout reads where the pointer and active window are and keeps nothing

Requirements

Windows 10 or later, Stream Deck app 6.9 or later, Windows PowerShell 5.1 (built in)

If something does not work, ask through the Support link.

Stream Deck + dials: turn to set how dark a monitor goes or the timer's minutes (also while it runs), push to start or stop; the touch strip shows the state.
