G901 · UHD VIDEO PROCESSING

Seamless UHD Switching & Front-End Video Processing

Five Inputs. One Controlled Output. Multiple Display Possibilities.

G901 combines seamless source switching, multi-view processing and programmable output control in a compact hardware processor.

Use it as a standalone UHD multi-viewer or as a front-end processing layer for GeoBox edge blending systems, video walls and LED displays.

What G901 Does

G901 provides a dedicated hardware layer for selecting, combining and adapting video sources before they reach the final display system.

Seamless UHD Source Switching

Change Sources Without Display Re-Synchronization

Switch between up to five connected sources while maintaining a continuous output signal. Avoid unnecessary signal interruptions and projector or display re-synchronization during source changes.

PiP, PoP & Multi-View Processing

Combine Multiple Sources on One UHD Canvas

Display up to four source windows using picture-in-picture, side-by-side or predefined split-screen layouts. PiP windows support adjustable size, position and aspect ratio.

Front-End Processing for Multi-Display Systems

Add Source Flexibility to Existing Display Processing

Place G901 upstream of a GeoBox edge blending processor or video wall controller to introduce source switching and multi-view layouts without changing the downstream display architecture.

Programmable Output Resolution & Timing

Adapt the Output to the Display System

Define custom output resolutions and timings for non-standard LED canvases, ultra-wide displays and specialized AV applications, within the supported signal bandwidth.

Typical System Architecture

One Front-End Processor. Multiple Downstream Possibilities.

G901 can operate as a standalone UHD switcher and multi-viewer, or as a front-end processor that adds source management and layout control to an existing multi-display architecture.

Architecture 01 · Front-End Integration

One Source Canvas. Multiple Displays.

G901 manages source selection and multi-view layouts; downstream GeoBox hardware handles distribution, geometry or edge blending.

Architecture 02 · Standalone Processing

Multiple Sources. One UHD Output.

Switch or combine connected video sources into one controlled output for a UHD display or compatible LED controller.

UHD Display / LED Processor

Predefined multi-view layouts are supported. PiP adjustments are more flexible; fully free-positioned window composition is the role of S902.

System integration advantage: Separate source switching and canvas composition from the final display processing. System integrators can introduce different source layouts while retaining the appropriate downstream display architecture.

G901 separates source management from display processing. It handles switching, multi-view composition and output formatting, while downstream GeoBox processors manage image distribution, geometry correction or edge blending as required.

This modular approach allows system integrators to introduce new source layouts and operating modes without replacing the existing display-processing architecture.

Actual video formats depend on source timing, chroma, colour depth, cable bandwidth and downstream equipment. High-resolution input capability does not imply identical output capability. Confirm unusual custom timings before deployment.

Consider Another GeoBox — Product Selection

G901 is ideal for seamless switching, predefined multi-view layouts and a single programmable output. Consider these alternatives when the project requires greater composition freedom or more UHD output channels.

Flexible Multi-Source Composition

Need Freely Positioned Video Windows?

Consider GeoBox S902

Choose S902 when the application needs independently movable and layered source windows, alpha blending, presentation transitions or two UHD outputs. S902 prioritizes flexible canvas composition rather than G901's programmable output timing and image orientation features.

Best fitControl rooms, presentation environments and advanced multi-source layouts requiring free window positioning.

Multiple UHD Display Outputs

Need Independent UHD Output Channels?

Consider GeoBox G902 / G904

Choose G902 or G904 when the main task is to crop, scale and distribute a high-resolution canvas across two or four UHD displays. Both offer programmable output control, with additional channels for multi-display architectures.

Best fitUHD video walls, large LED canvases and projector systems requiring multiple independently processed outputs.
