Overview

All FLEX Matrix chassis include a built-in video wall processor — no external controller required. A single source can be tiled across multiple displays in configurable grid layouts with bezel correction. Video wall zones can run simultaneously alongside normal matrix routing and multiview outputs on the same chassis.

Supported Layouts

The FLEX chassis supports flexible video wall configurations across any combination of output ports:

• 1×2, 1×3, 1×4 (horizontal or vertical strips)
• 2×2, 2×3, 2×4
• 3×3, 3×4, 4×4
• Custom non-rectangular layouts
• Multiple independent video wall zones simultaneously on one chassis

Configuration Steps

1. In the FLEX web GUI, navigate to Video Wall.
2. Click New Wall and name the video wall zone.
3. Select the output ports that form the wall. Assign each output to its physical position in the grid (e.g., Row 1 Col 1 = display top-left).
4. Set the grid layout (e.g., 3×3).
5. Enter bezel compensation values:
   • Horizontal bezel: Measure the inner bezel width between adjacent displays (left–right), in millimeters.
   • Vertical bezel: Measure the inner bezel height between adjacent displays (top–bottom), in millimeters.
6. Assign the source input to the wall zone.
7. Click Apply. Each display renders its assigned tile of the source image.

Bezel Compensation

Bezel compensation crops the source image behind each display’s physical bezel so content appears visually continuous across all panels. Measure the inner edge to inner edge gap between adjacent screen surfaces — not the outer frame. Enter values in millimeters.

Tip: Use a full-width gradient or grid test pattern to verify bezel alignment before handoff.

Multiple Simultaneous Video Walls

A single FLEX chassis can run multiple independent video wall zones at the same time. For example, on a FLEX-MF24X36:

• Zone A: Outputs 1–4 — 2×2 wall showing sports feed
• Zone B: Outputs 5–8 — 2×2 wall showing news feed
• Outputs 9–36: Normal matrix routing, individual displays

Video Wall + Multiview

Outputs not assigned to a video wall zone can simultaneously operate in Quad View or PiP multiview mode. The FLEX chassis manages all display modes independently per output.

Switching Video Wall Sources

Change the source feeding a video wall zone without reconfiguring the layout:

• Web GUI: Select the wall zone, change source, apply
• RS-232: SET WALL wallname SOURCE input_number\r
• TCP/IP API or control system preset

Best Practices

• Use identical display models (same panel size, bezel width, resolution) for cleanest results
• Label output cables by grid position (R1C1, R1C2, etc.) during cable pulls
• Assign static IPs to all FLEX-CATRX receivers used in wall zones for reliable web GUI management
• Power on the chassis before displays to ensure proper EDID negotiation
