G400 series
4K Input to Multi-Display Processing
G406 · G408 · G406S
Process 4K and ultra-wide source signals into 2, 4 or 8 independently controlled outputs for video walls, multi-display systems and projector-based installations.
2 / 4 / 8 outputs · Independent cropping, scaling & rotation · Frame-synchronized processing · Custom output resolution
One Processing Platform for Video Walls, Mixed Display Layouts and Projection Systems
Distribute one high-resolution source across multiple displays with independent cropping, scaling, positioning and bezel adjustment for every output.
Best for: LCD video walls, command displays, presentation walls and multi-monitor visualization systems.
Combine portrait and landscape displays while independently adjusting image rotation, image position and aspect ratio for each screen.
Best for: creative display walls, asymmetric layouts and installations combining different screen orientations.
Prepare cropped, scaled and synchronized images for multiple projectors while leaving geometry correction and edge blending to projectors that already provide those functions.
Best for: multi-projector systems where source distribution and image preparation are required upstream of the projectors.
CORE PROCESSING
WHAT G400 DOES
Control How High-Resolution Content Is Distributed Across Multiple Displays
The G400 Series separates the source canvas from the physical display layout.
Each output can independently select, crop, scale, position and orient the required image region, allowing the display system to be configured without rebuilding the original content.
Image Cropping & Distribution
Divide One High-Resolution Canvas Across Multiple Displays
Select the required image region for each output and distribute one 4K or ultra-wide source across multiple FHD, WUXGA or custom-resolution display channels.
Independent image positioning and edge adjustment allow the visible canvas to be aligned with the physical display layout rather than being fixed by the original source format.
Typical applications
- LCD video walls
- Multi-monitor display systems
- Ultra-wide presentation surfaces
- Multi-projector installations
- Cascaded display systems
Independent Scaling & Positioning
Match Each Output to the Required Display Area
Each output channel can independently resize and reposition its assigned source region.
This allows displays with different visible areas, bezel dimensions or installation positions to be aligned without changing the source content.
Image Rotation & Aspect-Ratio Control
Adapt Content to the Physical Display Orientation
Each processing channel can independently adjust image orientation and aspect ratio according to the connected display.
Available image operations include:
- 90° / 180° / 270° rotation
- Mirror / flip
- Independent scaling
- Image positioning
- Aspect-ratio adjustment
- Pixel-based edge adjustment
- Bezel compensation
Portrait and landscape displays can therefore be combined within the same system without preparing separate source content for each orientation.
Note:
For 90° / 270° portrait processing, the G400 Series supports source signals up to 4K30. Applications requiring 4K60 source processing in portrait orientation should use the G900 Series.
Custom Output Resolution
G400 supports user-defined output resolution and timing for downstream devices that require non-standard signal formats.
This is particularly useful when working with:
- dvLED controllers and custom-resolution display systems
- Applications requiring a specific output refresh rate, such as 50 Hz
- Downstream devices requiring user-defined output timing
Multi-Source Display Assignment
Assign Different Sources Within the Same Four-Display System
G406 adds flexible multi-source assignment for applications requiring different content on different displays.
Its HDMI and DisplayPort inputs can be assigned to different processing channel groups, enabling configurations such as:
- One source across all four displays
- Separate sources on different displays
- Mixed source assignments within one four-screen wall
- Different operating layouts stored as system profiles
For suitable four-display installations, this can reduce the need for an additional external matrix switcher.
Model note: Multi-source assignment is a specific advantage of G406. G408 and G406S are primarily optimized for high-channel-count source distribution and image processing.
Projector Overlap Preparation
Prepare Each Projector Image Before Warp & Blend
G400 can crop the appropriate source region for each projector and include the required overlap area between adjacent outputs.
The downstream projectors then perform:
- Geometry correction
- Edge blending
- Optical alignment
This architecture is particularly useful when the projectors already provide sufficient geometry and edge-blending capability, but the system still requires flexible source cropping, distribution, scaling, custom output timing and synchronization.
Scale to Larger Video Walls
Add Processing Channels as the Display Array Grows
G400 processors can be combined as larger video walls require additional display outputs.
The processor configuration is selected according to the number of displays rather than forcing the complete wall into a single fixed-output chassis.
3 × 3 Video Wall
9 displays
1 × G408 + 1 × G406S
G408 provides eight independently processed outputs, while G406S adds two additional processing channels.
Nine channels are assigned to the 3 × 3 display wall, leaving one additional output available.
10 processing outputs available · 9 displays used
4 × 4 Video Wall
16 displays
2 × G408
Two G408 processors provide sixteen independently controlled output channels — one processing channel for each display in the 4 × 4 video wall.
16 processing outputs · 16 displays
High-Resolution Processing without PC-Based Rendering
4K60 & Ultra-Wide Input
Process UHD and DCI 4K signals as well as ultra-wide source formats for large display canvases and multi-screen applications.
RGB 4:4:4 Processing
RGB / YUV 4:4:4 processing preserves fine text, graphics and image detail required in professional AV, visualization and presentation environments.
Flexible Output Formats
Generate multiple independently processed display outputs, with custom output resolution available when standard formats do not match the downstream device.
High-Quality Video Processing
10-bit processing, high-quality scaling and motion-adaptive video processing maintain image quality through cropping, scaling and format conversion.
Designed for Fixed AV Infrastructure
Frame Synchronization
Hardware frame synchronization maintains stable timing across multiple output channels for multi-display or multi-projector applications.
Profile Saving & Recall
Store display configurations for different content arrangements, operating modes or physical layouts and recall them without rebuilding the system.
Programmable EDID
Configure EDID settings to manage source compatibility and define the preferred input format for different system requirements.
Custom Output Resolution & Timing
Create non-standard output formats for compatible displays, projectors and dvLED controllers requiring specific resolutions or timings.
Input resolution and output timing are independently managed by the processor.
50 Hz Signal Handling
Maintain 50 Hz operation where required, reducing unnecessary frame-rate conversion in broadcast, European AV and other 50 Hz workflows.
UWM PC Tool
Configure cropping, scaling, rotation, output timing and system layouts through the GeoBox UWM control software during installation and commissioning.
External Control
Integrate GeoBox functions with third-party control systems for remote operation, preset recall and system automation.
Standalone Hardware Processing
Dedicated video-processing hardware operates independently from a general-purpose computer, operating system or graphics card.
This provides predictable operation for permanent AV installations.
Separate the Source Canvas from the Display Layout
A high-resolution source provides the complete visual canvas.
G400 independently selects and processes the required region for each downstream display, applying cropping, scaling, positioning, rotation, bezel compensation and output timing before generating synchronized display signals.
