Video Wall Processing
Control how one image or multiple sources are managed across synchronized displays.
- Image segmentation across displays
- Per-output control
- Frame-locked synchronization
- FPGA-based processing
- Multi-view and seamless switching
Quick Capabilities Overview
Display Segmentation
Define how one image is distributed across multiple displays
Per-Output Control
Adjust scaling, cropping, rotation, and layout per display
Multi-Source Processing
Manage multiple inputs with PiP, PoP, and multi-view
Signal Synchronization
Keep outputs frame-synchronized and stable
FPGA-Based Processing
Consistent signal behavior regardless of PC or GPU performance
What You Can Control in the System
Image Splitting and Layout
A single input signal can be divided into multiple output regions.
- define how the image is split across displays
- assign image regions per screen
- support irregular layouts beyond standard grids
Per-Output Image Control
Each output can be adjusted independently:
- scaling and cropping per output
- bezel compensation
- image rotation
- independent position control
Free-Angle Image Rotation for Creative Video Walls
G413 Supports image rotation at free angles for video walls that do not follow standard portrait or landscape layouts.
- free-angle image rotation
- support for asymmetric screen arrangements
- align content to unusual display orientations
- reduce content redesign in creative layouts
Multi-Source and Free-edit-windowing
- PiP / PoP / multi-view
- multiple sources on one canvas
- Seamless switching or various transition effect
Signal Synchronization
- frame-locked outputs
- stable timing across screens
- consistent behavior during switching
Input Flexibility
The system accepts a wide range of input formats.
- up to 4K / 8K input depending on model
- support for non-standard resolutions
- programmable EDID to match system requirements
This allows connection to PCs, media players, and servers without redesigning content.
What This Means in Practice
- No need to re-edit content for layout changes
- Multi-screen behavior remains predictable
- Display replacement is easier
- One system supports different sources over time
