The KYSTAR Hxs Series is a professional LED receiving card series for LED display signal receiving, image output, grayscale correction, and cabinet-level display management.
The series includes H5s, H8s Pro, H10s, and H12s. As a receiving card for LED display systems, Hxs Series receives display data from the sending device, converts it into signals recognizable by driver ICs, and helps assemble the content into a complete image on LED display screens.
Designed for fine-pitch LED displays, rental LED cabinets, fixed LED video walls, commercial displays, conference screens, control rooms, and creative LED screens, Kystar’s Hxs Series provides high image quality, flexible screen mapping, calibration support, backup protection, and reliable operation for professional LED display projects.
