VigilLink M814 4-Channel 4K/2K Modular Edge Blending Processor

VigilLink M814 4-Channel 4K/2K Modular Edge Blending Processor

The VigilLink M814 4-Channel 4K/2K Modular Edge Blending Processor is a professional video processing system designed for seamless multi-projector displays, image warping, and immersive projection environments. Featuring four independent processing modules, support for 4K60 video inputs, and HDMI outputs up to 2048 x 1080 at 60Hz, the M814 controls four projectors from one chassis.

Designed for professional AV integrators, simulation facilities, museums, entertainment venues, and commercial projection installations, the M814 provides extensive control over complex multi-projector arrangements. Each processing module features two HDMI 2.0b inputs, one DisplayPort 1.2a input, and one VGA input, allowing integration with multiple video sources. Advanced image geometry correction aligns projected content across flat, curved, panoramic, and corner-wall surfaces. Four-direction edge blending combines overlapping projector images into continuous displays, while independent RGB gamma correction and black-level compensation help maintain consistent image appearance. The integrated video wall processor supports image splitting, cropping, scaling, and configurable overlap regions without requiring an external video splitter.

The M814 incorporates a 10-bit video processing engine with motion-adaptive deinterlacing, programmable EDID, HDR-to-SDR conversion, and synchronized output capabilities. Picture-in-Picture (PIP) and Picture-Outside-Picture (POP) functions support flexible multi-source presentations, with up to eight input contents displayed across the four-channel system. HDMI loop-through connections allow compatible GeoBox processors to be cascaded for larger installations. Front-panel controls, infrared operation, RS-232, USB, Ethernet, and the GeoBox Control Tool provide multiple configuration methods. Its compact professional chassis supports demanding installations requiring continuous operation and detailed projector alignment.
