M810 SERIES

Multi-Projection Processing with Flexible Geometry Control

Scalable 4K video processing for multi-projector edge blending, geometry correction and high-resolution display systems. Start with the outputs required for the project and expand larger projector arrays by combining synchronized M810 processors.

What M810 Does

The M810 Series provides the core processing tools required to build seamless multi-projector displays, from small projector groups to larger synchronized arrays. Each processor handles independent image distribution, geometry correction and edge blending, while multiple units can be combined as the system scales.

Image Cropping & Distribution

Crop and distribute selected areas of a high-resolution source across multiple outputs. Each output can capture and position the required image region independently, allowing one source canvas to drive multi-projector layouts without pre-splitting the content.

image crop and distribution

Four-Side Edge Blending

Edge blending can be applied independently on all four sides of each output, supporting horizontal, vertical and multi-row projector arrangements. Overlap regions can be adjusted to create a continuous image across multiple projectors.

Edge blending and related blend-zone adjustments apply to M812, M813 and M814.

Advanced Geometry Correction

Correct image geometry for flat, curved, angled or irregular projection surfaces. Independent control points allow the projected image to be aligned to the physical screen while keeping the source workflow unchanged.

Black-Level Uplift

Raise the black level of non-overlap areas to better match the brightness of blended regions. This helps reduce visible differences in dark scenes across multi-projector installations.

Need Multi-Source Layouts Across the Full Canvas?

M810 is designed primarily for image distribution, geometry correction and edge blending. Its built-in PIP / POP function operates within an individual processing channel and does not extend across the complete edge-blended canvas.

For multi-source or multiview layouts across the full projection surface, add an S902 or G901 upstream of the M810 Series.

S902 for freely editable multi-window layouts.
G901 for fixed multiview / PiP workflows and applications requiring programmable output timing.

Video Performance

The M810 Series preserves professional video quality throughout the processing pipeline, supporting full-chroma processing, high-resolution source formats and deterministic FPGA-based operation.

FPGA

Dedicated Hardware Processing

Cropping, scaling, geometry correction, blending and output synchronization are handled by dedicated FPGA processing, without dependency on an operating system or GPU-based processing environment.

Engineering Features

System-level functions simplify integration, commissioning and long-term operation in fixed professional AV installations.

Frame Synchronization

Synchronizes outputs to maintain stable timing across multi-projector installations and reduce visible timing differences between display channels.

Profile Saving & Recall

Save complete system configurations for fast recall during operation, maintenance or different presentation modes.

Programmable EDID

Configure EDID settings to manage source compatibility and define the preferred input format for different system requirements.

Custom Output Timing

Define custom output resolution and timing when the display requires a non-standard format, including dvLED applications and projector systems operating at 50 Hz.

GCT PC Tool

Configure and manage GeoBox settings from a PC for faster installation, alignment and commissioning workflows.

External Control

Integrate GeoBox functions with third-party control systems for remote operation, preset recall and system automation.

Typical System Architecture

M810 is typically positioned between the source system and multiple projectors, keeping geometry correction, image distribution and blending independent from the playback platform.

The following example shows an M813 in a three-projector configuration:

The source system provides the required canvas resolution, while the M810 Series independently crops, scales, corrects geometry and blends the image for each projector output. Display alignment therefore remains independent of the media player or content application.

Scale Beyond One Processor

Multiple M810 processors can operate as synchronized processing nodes, allowing the same architecture to scale beyond the outputs of a single unit.

Multi-Source Layouts

When multiple live sources need to be positioned across the complete blended canvas, an S902 or G901 can be placed upstream of the M810 Series. The upstream processor creates the multi-source canvas, while M810 handles projector-side cropping, geometry correction, edge blending and output synchronization.

Choose M810 When

Need multiple sources across the full canvas?

Pair the M810 Series with an S902 or G901 upstream to create the multi-source layout before projector-side geometry correction and edge blending.

Consider Another GeoBox
