Daisy-Chain Overview

Daisy-Chain Overview

Daisy-Chain Setup Using Internal Videowall Processor

DISPLAX TILE includes an internal videowall processor that allows multiple TILE units to be merged into a single display.

In this configuration:

  • TILE units are DisplayPort daisy-chained

  • TILE units are also RS232 daisy-chained

  • The layout is configured using Screen Control Software

  • The Operating System detects one screen per daisy-chained group

Daisy-Chaining Resolution Behaviour

All connected displays in a daisy-chain group share a maximum resolution of 4K (3840 × 2160), regardless of the number of monitors connected.
This means:
  1. The final merged resolution cannot exceed 3840 × 2160
  2. The resolution needs to be scaled to match the 16:9 aspect ratio 

Example Setup (6 × 1 Video Wall)

Example layout:

  • 6 TILE units

  • 1 row × 6 columns

  • Portrait orientation


Each TILE resolution:
1080 × 1920  

Total resolution:
6480 × 1920  

Optimal resolution: (scaled)
3840 × 1138

Maximum Units

  • Up to 6 TILE units can be daisy-chained in a single sequence

Operating System Behavior

When using daisy-chain mode:
  1. The OS identifies all connected TILE units as a single display
  2. Configuration is simplified
  3. Individual monitor control at OS level is not available

Software Requirement

To merge screens and configure the video wall:

  • Screen Control Software must be used

  • This software manages:

    • Screen mapping

    • ID assignment

    • Layout configuration

    • Bezel correction

RS232 daisy-chain is mandatory for proper screen identification and merging.
