Video Matrixes
Learn how to use Matrixes for video walls
Matrix configurations use video wall processors to distribute signals from source devices to multiple display monitors.
Video wall processors, also called splitters, matrix switchers, video wall controllers, or signal switches, accept multiple inputs and distribute them to displays in controlled patterns. These devices split single signals or organize multiple signals across displays according to configuration requirements.
Cost Considerations: Video wall processors range in price based on capability. 4-input HDMI splitters typically cost $200-300. 8-input splitters and 4K-capable units range from $500-600.
Processing Requirements: Matrix devices handle signal processing, reducing graphics card requirements on source devices. Systems with appropriate CPU performance operate effectively without high-end graphics cards.
Resolution Compatibility: Video splitter input/output specifications must align with source device and display capabilities. Output resolution cannot exceed source device maximum resolution. For example, a 1920×1080 signal distributed across 4 screens results in 480×270 per screen. Resolution division affects content clarity and may introduce unintended blurring.
Multi-Stream Transport Hubs
Multi-stream transport (MST) hubs provide functionality similar to matrix video wall splitters with distinct operational characteristics.
Connectivity: MST hubs connect to source devices via DisplayPort or USB-C ports. The hubs support up to 4 screen connections, emulating multiple independent outputs from a single source device port.
Cable Management: MST implementations simplify cable routing compared to direct multi-screen connections. The 4-output limitation makes MST less suitable for video walls exceeding four screens.
MST vs. Matrix Processor Comparison
MST hubs and video wall processors operate differently:
Video Wall Processors: Take a single 1080p or 4K signal and split or stretch it across multiple screens. The processor divides one signal for display across multiple monitors.
MST Hubs: Receive multiple independent signal outputs from source devices and route them to individual screens. Each screen receives a discrete signal as if directly connected to source device HDMI ports.
Port Compatibility
MST Port Requirements: MST hubs are not compatible with HDMI connections. MST technology requires DisplayPort, Mini DisplayPort, or Thunderbolt cable connections. Hardware selection must account for connection type compatibility between source devices, MST hubs or matrix processors, and displays.
