Overview

Every output port on the FLEX chassis includes an independent scalar — each output can be set to a different resolution, regardless of the source’s native resolution or what other outputs are doing. This allows a single system to drive mixed display environments: 4K TVs, 1080p monitors, and HD projectors simultaneously from the same chassis without signal conversion hardware.

Per-Output Scaling

Scaling is configured per output port in the web GUI:

1. Navigate to Output Settings in the chassis web GUI.
2. Select the output port to configure.
3. Under Output Resolution, choose from:
   • Auto (EDID follow): Output resolution follows the connected display’s EDID. Recommended for most setups.
   • Manual override: Force a specific resolution (e.g., 1920×1080@60, 3840×2160@60, 1280×720@60).
4. Set the scaling mode:
   • Fill: Stretch to fill the output resolution (may change aspect ratio).
   • Fit (letterbox/pillarbox): Scale to fit with black bars to preserve aspect ratio.
   • Crop: Scale and crop to fill without bars.
5. Apply. The output immediately scales to the new resolution.

Supported Output Resolutions

• 3840×2160 @ 60/30/25/24Hz (4K UHD)
• 1920×1080 @ 60/50/30/25/24Hz (1080p)
• 1280×720 @ 60/50Hz (720p)
• 1024×768 @ 60Hz (XGA — for projectors)
• 1920×1200 @ 60Hz (WUXGA — for widescreen monitors)

EDID Management

EDID (Extended Display Identification Data) is the data a display sends to the source describing its supported resolutions and audio formats. Incorrect EDID handling is a common cause of no signal or wrong resolution on matrix systems.

EDID Modes

• Pass-through: The chassis forwards the connected display’s EDID directly to the source. Default mode. Works for most installations.
• Fixed EDID: The chassis presents a fixed EDID to all sources regardless of connected displays. Useful when displays have mismatched EDIDs or when sources must always output at a specific resolution.
• Custom EDID: Upload a custom EDID file to present specific capabilities to sources. Advanced use case for broadcast or specialized display environments.
• Copy EDID: Copy the EDID from a specific output and apply it to one or all inputs. Useful for establishing a consistent EDID baseline across all sources.

EDID Best Practices

• Use Fixed EDID when video wall displays have mismatched native resolutions or report inconsistent EDIDs.
• Use Fixed EDID when CATx runs are long — EDID pass-through over long CATx runs can occasionally be unreliable.
• Lock sources to their fixed EDID before finalizing installation to prevent sources from changing resolution during system updates or display swaps.
• For 4K sources: ensure the EDID presented supports 4K60 4:4:4 and HDR if the source needs to output HDR content.

Use Case: Mixed Display Environment

A typical large venue deployment with the FLEX-MF24X36 might have:

• Bar TVs (1080p60) — outputs scaled to 1920×1080
• Main feature display wall (4K60) — outputs at 3840×2160
• Projector (WXGA, 1280×800) — output scaled to 1280×800
• Operator monitors (1080p60) — outputs at 1920×1080

All from the same chassis, same sources, no external scalers needed.
