Video Walls
A video wall is a group of displays arranged in a grid to form one large screen. Inspire handles content stretching, bezel compensation, and synchronised playback across all panels.
Setting Up a Video Wall
- Navigate to Endpoints
- Click New Video Wall
- Configure the wall:
| Setting | Description |
|---|---|
| Name | Descriptive name (e.g. “Lobby Video Wall”) |
| Grid | Number of columns and rows (e.g. 3x2) |
| Panel Resolution | Resolution of each individual panel |
| Bezel Width | Physical bezel width in mm (for compensation) |
| Orientation | Landscape or portrait per panel |
- Assign a paired device to each panel position in the grid
- Save the video wall configuration
Content for Video Walls
Video wall endpoints work like any other endpoint — assign scenes as normal. Inspire automatically:
- Scales content to the total wall resolution
- Splits the rendered output so each panel displays its portion
- Compensates for bezels so content appears continuous across panels
- Synchronises playback across all panels
Bezel Compensation
Bezel compensation adjusts the content so that visual elements appear to continue behind the bezels rather than being cut off. Without compensation, lines and images are visibly disrupted at the screen boundaries. With compensation, the renderer shifts each screen’s viewport to “skip over” the bezel area, creating a seamless image.
How it works
Each display in the wall shows a slightly wider virtual viewport that accounts for the physical bezel width. The renderer calculates a virtual canvas that spans all screens plus the gaps between them, then offsets each display to show only its portion — with the bezel area excluded from the visible content.
For example, a 2x2 wall with 1920x1080 displays and a 20px bezel gap creates a virtual canvas of 3860x2180 pixels. Each screen’s viewport is shifted so that content appears continuous across the bezels.
Configuring bezel gap
Set the bezel gap value (in pixels) when creating or editing a video wall under Settings > Video Walls. Measure the physical bezel width of your displays and enter the equivalent pixel value.
| Bezel size | Typical pixel value |
|---|---|
| Ultra-narrow (1.7mm) | 3-4px |
| Narrow (3.5mm) | 6-8px |
| Standard (5.5mm) | 10-12px |
| Wide (8mm+) | 15-20px |
The exact pixel value depends on your display’s pixel pitch. Measure the total bezel width (left bezel + right bezel of adjacent displays) and convert to pixels using your display’s pixels per millimetre.
Mixed Orientations
Video walls can include panels in different orientations. Specify the orientation of each panel position in the grid configuration.
For best results, use identical display panels throughout the video wall. Mixed models may have slight colour and brightness differences.
Troubleshooting Video Walls
| Issue | Solution |
|---|---|
| Content misaligned across panels | Verify bezel width settings match physical bezels |
| One panel shows wrong content | Check panel assignment in the grid configuration |
| Synchronisation drift | Ensure all panels have stable network connections |
| Colour inconsistency | Calibrate all panels to the same colour profile |
