Amoonsky MS4K-C 4K LED Multi-Window Splicer | 10.5M Pixel Processing Power

4K LED Multi-Window Splicer

Amoonsky MS4K-C: 4K Multi-Window Splicer Processor with 10.5M Pixel Capacity

A high-performance 4K@60Hz splicer processor designed for large-scale LED video walls. Featuring 10.5 million pixel processing, 4 output channels with 8 DVI ports, multi-layer windowing, and seamless switching for professional display environments.

Beyond Basic Splicing

Large LED video walls demand more than simple signal distribution. The Amoonsky MS4K-C is a dedicated splicer processor that combines massive pixel processing capacity with intelligent multi-window management, enabling operators to drive expansive LED displays from a single, consolidated control point.

With native 4K@60Hz input support, a total processing capacity of 10.5 million pixels, and 4 independent output channels through 8 DVI interfaces, the MS4K-C handles LED wall configurations that would otherwise require multiple separate processors, reducing system complexity while increasing reliability.

Available in three variants — standard MS4K-C, SDI-extended MS4KS-C, and USB-extended MS4KU-C — the series adapts to broadcast, corporate, and standalone playback scenarios without hardware compromise.

Input Architecture

The MS4K-C provides a comprehensive input matrix covering 4K digital, standard digital, analog, and optional broadcast-grade interfaces, ensuring compatibility with virtually any signal source.

Interface	Quantity	Max Resolution	Notes
DisplayPort	1	3840×2160@60Hz	Primary 4K input
HDMI	3	HDMI3: 4K@60Hz	HDMI 1-2 standard; HDMI 3 is 4K capable
DVI	2	4K@30Hz	Dual DVI digital inputs
VGA	1	1920×1200	Legacy analog support
SDI	1	1080p@60Hz	Optional (MS4KS-C model)

4K Workflow: For true 4K@60Hz throughput, use the DisplayPort or HDMI 3 input. The DVI inputs support 4K@30Hz for applications where frame rate is less critical than resolution.

Output & Processing Capacity

The MS4K-C delivers its processed output through 4 independent channels, each driving up to 2.65 million pixels, for a combined total capacity of 10.5 million pixels.

Output Configuration

4 Output Channels / 8 DVI Interfaces — each channel provides dual DVI ports for maximum flexibility
1 Monitoring Output — dedicated preview/monitoring port for operator verification
4 Sending Card Slots — built-in support for standard LED sending cards, eliminating external hardware

Maximum Splicing Resolutions

Configuration	Resolution	Refresh Rate	Layout Type
Ultra-Wide Horizontal	15360×640	60Hz	Long banner / ticker displays
Balanced Widescreen	4608×2304	60Hz	Standard video wall ratio
Square Format	3072×3072	60Hz	Cube / art installations
Vertical Tower	960×8640	60Hz	Tall portrait displays

Capacity Note: The 10.5M total pixel capacity is distributed across all 4 output channels. The actual maximum resolution depends on how the pixel budget is allocated across your specific display configuration.

Multi-Window & Layer Management

The MS4K-C supports advanced multi-window operation, allowing operators to display multiple content sources simultaneously on a single LED wall.

2-Layer Architecture

Two independent display layers with priority control. Content on Layer 2 overlays Layer 1 with configurable transparency and positioning.

Up to 4 Windows

Display up to 4 simultaneous windows from different input sources. Each window supports independent sizing, positioning, and cropping.

11 Layout Templates

Built-in layout presets for common multi-window configurations, enabling instant switching between presentation modes without manual window adjustment.

Flexible Arrangement

Windows can overlap, tile, or be positioned freely across the entire display canvas. Supports both equal-split and asymmetric layouts.

Image Processing & Rotation

For installations where LED panels are mounted in non-standard orientations, the MS4K-C provides hardware-level image manipulation at full 4K@60Hz throughput.

Image Rotation

Rotate the output image by 90°, 180°, or 270° to match physically rotated LED panels. Processed at the hardware level with zero latency penalty.

Horizontal Flip

Mirror the display horizontally for rear-projection configurations or specialized creative installations.

Custom EDID

Program custom EDID data to communicate non-standard resolution requirements to upstream signal sources automatically.

Custom Resolution

Define arbitrary output resolutions to match any LED panel configuration precisely, beyond factory presets.

Operational Controls

The MS4K-C includes a comprehensive control feature set designed for both live operation and automated installations.

Live Operation

Seamless Switching — glitch-free transitions between input sources with no black frames or visual artifacts
One-Key Blackout — instant output kill for intermissions, emergencies, or content changes
Frame Freeze — lock the current display frame while switching sources behind the scenes
10 Mode Presets — save and recall complete system configurations for different show scenarios

Automation Features

Timed Power On/Off — schedule automatic system startup and shutdown for unattended installations
Timed LED Brightness — program brightness schedules to adapt to ambient lighting changes throughout the day
Audio Extraction — synchronized audio output from digital input sources

Control Interfaces

RS232 Serial — integration with show control, AV automation, and building management systems
Remote Control — infrared remote for quick on-site adjustments
Front Panel — direct hardware controls for standalone operation
