Projection window

The projection window is a window separate from the app’s main window. It’s the one you send to the projector’s monitor and what the service audience sees.

Dual-monitor setup

The typical use is:

Monitor 1 (laptop)	Monitor 2 (projector)
Main window	Projection window
Sidebar, program, preview, controls	Fullscreen, no borders, just the content being projected
You look at it while operating	The congregation sees it

Configure and open

1. Connect the projector to your computer via HDMI / DisplayPort / USB-C.
2. In your operating system’s display settings (macOS or Windows), pick “Extend display” (not “mirror”).
3. In the EFA Projection main window, look at the preview on the right — there’s a monitor selector that appears when more than one is connected.
4. If your setup is typical (laptop + projector), the app detects and pre-selects the second monitor. If you have more, you can switch with the dropdown.
5. Click Project. The app:
   • Opens a new window on the selected monitor.
   • Puts it automatically in fullscreen.
   • Leaves it without borders or window controls (decoration-less) so it fills the screen without distracting.
   • Focus returns to the main window so you keep operating from there.

Once open, the button changes to Projection Active (in green) to show the state.

Single-monitor setup

If your computer doesn’t have a second monitor (e.g. rehearsals or prep), you can:

• Open the projection window anyway, choosing the only monitor available. It will take over your screen in fullscreen — useful to preview how it looks.
• To return to the main window, click the main app in the Dock (macOS) or in the taskbar (Windows).
• Or simply don’t open the projection window while editing. Sync to the server isn’t affected — the window is only for display.

Only one projection window

For now EFA Projection supports one active projection window at a time. If you want to switch monitors during the service (rare):

1. Close the current window (Close projection button or Cmd + W with focus on that window).
2. Switch the monitor in the dropdown.
3. Click Project again.

Control from the main window

Everything you do in the main window is reflected in real time in the projection window:

• Change a slide → the projection window updates.
• Change a theme → the look changes.
• Black screen → the window goes to black.
• Clear → returns to the default state.

You don’t need to touch the projection window directly. In fact, avoid clicking on it — it doesn’t accept input.

Black screen and clear

Two different commands:

Action	How	Behavior
Black screen	Esc (in the main window)	Sends the projector to black but keeps the current slide; press another key to return.
Clear	Button in the preview	Returns the screen to the default state and resets the slide position.

Black screen is the most used — for transitions, announcements where the preacher wants no distraction, or pauses.

Show logo

From the preview → image icon button, or from the mobile remote control. Displays the organization’s logo full screen.

Useful for:

• Service opening.
• Long transitions between items.
• Showing identity when there’s no other content.

The logo is set from the web panel under Settings → Organization → Logo.

Background audio

Background audio is independent of the slide. Once you start it:

• Persists when you change slides.
• Persists when you go to black screen.
• Persists when you clear.
• Only an explicit command (Stop) or playing another audio stops it.

This is the typical pattern for background music during announcements — you want it to keep playing while the operator changes slides.

Background audio controls

In the preview there’s a strip with:

• Play / pause
• Stop (resets position to 0)
• Restart (returns to 0 and plays)
• Toggle loop (repeat when finished)
• Progress bar with current time and duration

These same controls appear in the mobile remote control, with the position synced in real time.

Video and YouTube

Different from audio: videos are projected as a slide. When you move to the next item, the video stops.

If you want a short looping video as a background, use an animated theme — it’s optimized for that.

Resolution and aspect ratio

The projection window uses the native resolution of the monitor you picked. If your projector is 1920×1080, the window fills that full resolution.

For non-standard projectors:

• 4:3 (1024×768) — the app adjusts automatically.
• 16:9 (1920×1080) — the most common case.
• Ultra-wide (21:9, 32:9) — works but some themes may need a position adjustment (centered text may look “lost”). Try a theme with left-aligned text.

Reposition if something looks off

If the monitor order changed (e.g. you unplugged and replugged the projector), the app re-reads the monitor list every 3 seconds and updates the dropdown. If the monitor you were using is no longer there, the app automatically selects another available one.

To force it:

1. Close the projection.
2. Verify the connected monitors in your system settings.
3. Return to the main window → the dropdown should have the updated monitors.
4. Click Project.

Close the projection window

When the service ends, Close projection from the preview, or from the projection window with Cmd + W. The main window stays open and the app doesn’t quit — you can keep editing content without projecting.
