LED WALL PROCESSING

LED Wall Video Processing

Hardware Processing for Professional LED Display Systems

Prepare, compose, crop and scale high-resolution source signals before they reach the LED controller.

From ultra-wide and portrait LED canvases to multi-source presentation walls, GeoBox provides dedicated hardware processing for custom output timing, source composition and predictable display behavior.

TYPICAL APPLICATIONS

Where GeoBox Fits

Non-Standard LED Canvases

Adapt standard video sources to ultra-wide, portrait or other non-standard LED canvas formats through cropping, scaling and custom output timing.

Typical systems: corporate LED walls, digital signage, architectural LED and visualization displays.

Multi-Source LED Walls

Combine several independent UHD sources into one LED canvas with flexible window positioning, resizing, layering and seamless switching.

Typical systems: control rooms, presentation spaces, sports venues and command environments.

Curved LED Geometry Correction

Correct bowing and geometry distortion when flat-plane video content is displayed on curved or irregular LED surfaces.

Typical systems: curved LED walls, immersive environments, architectural LED installations and virtual production.

Mixed Display Systems

Coordinate LED walls with LCD displays or projectors while maintaining consistent source processing and system timing.

Typical systems: experience centres, museums, hybrid presentation environments and simulation systems.

SYSTEM ARCHITECTURE

What Does the LED System Need to Manage?

The first step is deciding whether GeoBox needs to adapt a single source or canvas to the LED wall, or compose multiple independent sources before the LED controller.

STANDARD SOURCE → NON-STANDARD LED CANVAS

Adapt Content to a Non-Standard LED Canvas

Choose G900 or G400

Use GeoBox when a standard source needs to be cropped, scaled or reformatted before reaching the LED controller.

Typical requirements:

ultra-wide or portrait LED canvases
custom output resolution or refresh rate
source cropping and scaling
synchronized outputs
display configuration independent from the playback PC

MULTIPLE SOURCES → ONE LED CANVAS

Combine Multiple Sources on One LED Canvas

Choose S902

Use S902 when several independent sources need to be freely positioned, resized, layered or switched on the LED canvas.

Typical requirements:

multiple UHD sources
freely positioned windows
overlapping or layered content
alpha blending
seamless switching
reusable presentation layouts

Need Both Functions?

MULTIPLE SOURCES → MULTIPLE DISPLAY OUTPUTS

Distribute Multiple Sources Across a Larger Display System

Combine S902 + G900 Series

S902 first composes multiple independent sources into the required layout. A downstream G900 processor can then crop, segment and distribute that composed canvas across multiple display outputs.

Typical requirements:

multiple independent input sources
one coordinated high-resolution canvas
distribution across multiple LED processors or display sections
mixed LED / LCD / projection outputs
independent cropping and scaling for each output
synchronized output timing

Multiple Sources → S902 → G900 Series → LED Controller(s) → Display System

CURVED LED PROCESSING

Correct Geometry Before the LED Controller

LED controllers are designed to map and drive LED pixels accurately, but they do not necessarily correct the visual geometry created by curved or irregular display surfaces.

GeoBox UD100 Series adds real-time geometry correction upstream of the LED controller, allowing the image to be warped so that straight lines and visual proportions remain correct on the physical LED surface.

Without Geometry Correction

horizontal lines appear bowed
flat-plane content becomes distorted
visual proportions change across the curved surface

With UD100 Geometry Correction

real-time non-linear warping
fine geometry adjustment
image correction before the LED controller
independent from the LED sender ecosystem

SYSTEM RESPONSIBILITIES

Working with LED Controllers

GeoBox operates upstream of the LED controller, preparing and managing the video signal while the LED controller remains responsible for cabinet mapping, calibration and physical LED driving.
