Video Walls

TelemetryOS supports multi-screen video wall configurations through three implementation strategies: native multi-display output, daisy-chained displays, and video matrix processors. Video wall capabilities scale from two-screen installations to large-scale deployments exceeding 16 displays.

🚧

Advanced Video Wall Support

TelemetryOS software integrates with video walls of any size when hardware supports multi-screen operation. AV specialists or hardware resellers assist with setup and troubleshooting for complex video wall configurations.

Hardware Requirements

Video wall hardware scales based on display count and resolution requirements:

Hardware performance impact:

• GPU capabilities determine maximum resolution per output
• CPU performance affects content rendering
• Network bandwidth impacts content synchronization
• Storage capacity limits content cache size

TelemetryOS supports any resolution within hardware and display capabilities. Visual quality and resolution scale with hardware performance.

Hardware Selection

Video wall hardware selection involves technical complexity. Technology resellers provide product recommendations and setup guidance based on specific video wall size and deployment requirements.

Display Implementation Methods

Video walls implement through three primary methods, each with distinct characteristics:

Native Configuration

Native video wall configurations transmit direct signals from single device to multiple displays via independent outputs:

Architecture:

• Device with multiple video outputs (HDMI, DisplayPort, USB-C)
• Direct cable connection from device to each display
• Operating system manages display layout and positioning

Connection requirements:

• Compatible device with sufficient video outputs
• HDMI/DisplayPort cables for each display
• One cable per display (no signal splitting)

Display layout configuration:

• Operating system recognizes multiple displays
• Display arrangement configured through OS settings
• Positioning determines content flow across displays

Resolution considerations:

Source resolution must exceed individual screen resolution to maintain full resolution across multiple displays. Pixel count requirements scale with display quantity and arrangement.

Recommended scale: Native configurations work effectively for video walls up to 3-4 screens due to resolution and processing limitations.

Daisy Chain Configuration

Daisy chaining connects displays in sequential series from single device output:

Signal flow:

1. Device outputs to first display
2. First display passes signal to second display
3. Second display passes to third (continues through chain)

Hardware requirements:

• Compatible source device with DisplayPort output
• Professional displays with daisy chain support (DisplayPort in/out)
• DisplayPort cables between displays

Display vendors specify daisy chain capabilities. Consumer displays typically lack daisy chain functionality; professional-grade displays include this feature.

Cost considerations:

Daisy chaining eliminates matrix processors but requires professional displays with daisy chain capabilities (typically higher cost than standard displays).

Matrix Configuration

Matrix configurations use video wall processors to distribute signals from source devices to multiple displays:

Architecture:

• Source device(s) output to video matrix processor
• Matrix processor splits and distributes to all displays
• Processor handles bezel compensation and scaling

Video matrixes support large-scale installations (5+ displays) and complex configurations. See Video Matrixes guide for detailed matrix setup.

Matrix advantages:

• Supports unlimited display count (within matrix capacity)
• Centralized signal management
• Advanced features (bezel compensation, rotation, scaling)
• Multiple source device support

Matrix considerations:

• Additional hardware cost (matrix processor)
• Installation complexity
• Processor performance determines maximum resolution
• Potential single point of failure (processor failure impacts all displays)

Video Wall Configuration

Video wall configuration encompasses aspect ratio calculation, playlist configuration, and content zone management.

Aspect Ratio Calculation

Video wall aspect ratios derive from combined dimensions of all displays:

Standard single display: 16:9 (landscape) or 9:16 (portrait)

Multi-display calculations:

Calculation method:

1. Identify physical layout (rows × columns)
2. Multiply base aspect ratio by display count in each dimension
3. Simplify resulting ratio

Playlist Aspect Ratio Configuration

Playlists configure with aspect ratios matching physical video wall layout:

📘

Aspect Ratio Display Note: Playlist aspect ratio settings provide editor preview convenience and do not affect device output. The setting enables visual editor matching to physical device aspect ratios without impacting actual display output.

Configuration location: Playlist Configuration tab > Aspect Ratio setting

Available options:

• Standard ratios (16:9, 9:16, 4:3)
• Custom ratio entry (for video wall-specific ratios)

Playlist editor preview updates to match configured video wall layout, supporting accurate content positioning during design.

Playlist Zones for Video Walls

Playlist Zones partition playlist pages into separate content sections:

Video wall applications:

• Divide content across different screens in video wall
• Each zone displays independent content on specific screens
• Zone boundaries align with physical display boundaries

Zone layout example:

2×2 screen grid video wall with corresponding zone layout:

Each zone displays unique content on corresponding physical screen within video wall.

Zone configuration:

• Zone dimensions match individual display resolutions
• Zone positioning aligns with physical display arrangement
• Content assigned independently to each zone

See Playlist Zones for zone configuration details.

Bezel Compensation

Display bezels (frames) create gaps between screens in video wall configurations:

Compensation methods:

• Content scaling to account for bezel width
• Zone padding to prevent content overlap with bezels
• Matrix processor bezel compensation features

Bezel width (typically 1-5mm per side) impacts visual continuity across displays. Content design should account for bezel gaps or use matrix processor compensation.

Common Use Cases

Corporate lobbies: Large-format brand displays with synchronized content (2×2 or 3×2 configurations)

Retail signage: Product showcases with multi-angle presentations (horizontal 1×2 or 1×3 layouts)

Control rooms: Multi-source monitoring with independent content per screen (2×3 or 3×3 grids)

Event displays: High-impact visual presentations with synchronized video (2×1 or 3×1 horizontal)

Transportation hubs: Large-scale information displays with departure/arrival boards (2×4 or larger grids)

Sports venues: Replay displays and statistics with synchronized content across large surfaces

Configuration Specifications

Video walls configure through combination of hardware setup (display arrangement, signal routing), operating system configuration (display positioning), and TelemetryOS playlist settings (aspect ratio, zones).

Required Configuration

• Physical display arrangement and mounting
• Signal routing (native, daisy chain, or matrix)
• Operating system display positioning
• Playlist aspect ratio matching physical layout

Optional Configuration

• Playlist zones for multi-content layouts
• Bezel compensation (via matrix processor or content design)
• Display synchronization settings
• Content-specific scaling and positioning

Limitations

• Native configurations limited to 3-4 displays (hardware-dependent)
• Daisy chaining requires professional displays with DP in/out
• Matrix configurations require additional hardware investment
• Source resolution must support total pixel count across all displays
• Display positioning accuracy critical for seamless content flow
• Bezel gaps create visual discontinuity unless compensated
• Network bandwidth impacts content sync across multiple devices (multi-device walls)
• Matrix processor performance determines maximum resolution and display count
• Aspect ratio mismatches cause letterboxing or pillarboxing
• OS display configuration persistence varies by platform (may require reconfiguration after updates)
