TV Wall Output turns one Apple TV into four independent 1080p outputs. With an inexpensive HDMI “video wall” controller set to 2×2 mode, the Apple TV’s single 4K signal is split into four 1080p quadrants — and LightLoop renders something different in each one. A common live-production setup:

Audience screen

Program Output — the full presentation your congregation sees.

Confidence monitor

Stage Display — current lyric/verse, the next preview, a clock, and speaker timers.

Switcher input 1

Lower-Third Overlay — song/Bible text only, for keying over a livestream.

Switcher input 2

Overlay Alpha (DSK) — the same lower-third as a solid-white fill matte for downstream keying.
TV Wall Output requires an external 2×2 HDMI wall controller set to 2×2 mode at 16:9 aspect ratio. LightLoop renders the four quadrants; the controller splits them across your physical screens.

​
Enabling TV Wall

TV Wall is configured per feed in the web app.
1

Open the Feeds tab

In the web app, go to Feeds and find the feed connected to the Apple TV you want to drive.
2

Turn on TV Wall Output

Toggle TV Wall Output on the feed card. A Config button appears.
3

Configure the quadrants

Click Config to open the TV Wall Output Config modal and choose what each quadrant displays.
4

Present

Connect the Apple TV through your 2×2 controller (2×2 mode, 16:9) and start presenting. The TV wall grid replaces the normal full-screen output.

​
Quadrant backgrounds

Each of the four quadrants (Top Left, Top Right, Bottom Left, Bottom Right) is set to one of:

Empty (Black)

A solid black quadrant — use it for unused outputs or as a clean black field behind an Alpha overlay.

Program Output

The full presentation — identical to normal full-screen output (songs, Bible, video, images, monitors, calendars, countdown banners). Rendered at full 1080p and scaled into the quadrant so it’s pixel-accurate.

Stage Display

A confidence monitor: the current lyric/verse in large text, a Next preview, optional clock and live video/thumbnails. Lyric and verse changes animate directionally (up on next, down on previous).

Media

An independent looping image or video pulled from your Media Library — separate from the program playback. Optional loop and mute.

​
Overlays — lower-thirds & alpha

Any quadrant that isn’t a Stage Display can also carry a foreground overlay:
OverlayWhat it shows
No OverlayBackground only.
Lower-Third OverlaySong lyrics / Bible text rendered as a lower-third on top of the background.
Overlay Alpha (DSK)The same lower-third rendered as a solid-white fill matte on black for downstream keying.
Lower-thirds apply to Songs and Bible items — the only content types with separate foreground (text) and background layers. All other content is full-screen and has no separate lower-third.

​
Alpha for downstream keying

The Overlay Alpha quadrant renders an exact copy of the lower-third with every color driven to 100% white on black, preserving the true coverage of text, drop shadows, background shapes, borders, and media. Feed it into an ATEM (or any switcher) downstream keyer as the key/alpha, and the matching Lower-Third Overlay quadrant as the fill — and your song and Bible text keys cleanly over your livestream.
A typical streaming rig uses two quadrants for one lower-third: one Lower-Third Overlay (fill → switcher input 1) and one Overlay Alpha (key → switcher input 2), both using the same template.

​
Lower-third templates

Lower-Third and Alpha overlays use reusable lower-third templates that give you precise control over placement and styling — including text that shrinks to fit a defined area rather than the whole screen. Templates are created in a visual editor (drag-to-move, drag-to-resize zones on a 16:9 canvas) and selected per overlay quadrant. There are two template types:

Song templates

A single lyrics zone with full styling and shrink-to-fit.

Bible templates

Two independent zones — reference (e.g. “John 3:16”) and verse text — each placed and styled separately.
Each zone supports:
  • Font (DM Sans, Montserrat, Oswald, Playfair Display, Fredoka, OPTI Improv Wide Nine), max size, color, bold/italic/ALL CAPS, alignment, vertical alignment, stroke, text background, and drop shadow.
  • Box styling — padding, border, corner radius, and a background that fills the zone (solid color, gradient, or a looping image/video from your Media Library) with hidden overflow.
  • Transitions — cross-dissolve (default), directional (up/down following navigation), or cut.
  • Hide when empty — automatically hide the whole overlay when there’s no text to show.
  • Blank-slide media — optionally show a full-screen watermark or holding graphic (image or looping video) on blank slides instead of going empty (when Hide when empty is on).
  • Hide Media (off by default) — by default, non-song/bible items (videos, images, monitors, etc.) play full-view in an overlay quadrant, with a full-frame Alpha matte for keying. Turn this on to show only lower-thirds/alpha and leave the quadrant blank for other content.
Templates are per-user and reusable across feeds. When no template is selected, a simple bottom-third bar is used.

​
Stage Display extras

A Stage Display quadrant has a few options of its own:

Show Clock

A live clock (AM/PM) pill in the upper-right corner.

Show Countdowns

Mirror program countdown banners onto the stage too — shrinking the stage view to make room without covering the Next preview.
For timed media (video, audio, songs with a track), the Stage Display also shows a small time-remaining pill, and stage-only speaker timers appear as a pill in the upper-left corner. Set these up under a playlist item’s Actions → Countdown Timer (see Playlists).
Dynamic, server-rendered content (Planning Center monitors and calendars) renders in Program and Media quadrants. In a Stage Display quadrant they appear as a labeled placeholder, since the stage view is built for lyrics and verses.

​
Performance

LightLoop reuses a single decode of the program video across quadrants — one AVPlayer can feed multiple on-screen layers — so showing the same video in the Program and Stage quadrants doesn’t double the decoding cost. Media-quadrant images and videos are streamed/cached independently.
