  • Support 32 groups of RGB signal output
  • Loading capacity: 256*256 pixels
  • Low latency
  • Supports Auto-Calibration
  • Seam compensation
  • Support 3D display
  • Improved grayscale performance at low brightness
  • Smart panel marking good for maintenance
  • Auto-recognizes sequence of connected receiver cards
  • High-precision point-by-point calibration in the brightness and the chromaticity
  • Supports smart module to save calibration coefficients and other information on module
  • Temperature, humidity, power supply voltage monitoring on cabinet and fan rotating control
  • Cable Detection
  • Supports receiver card backup and power supply backup
  • Various freeform display designs like spherical display, creative display, etc.
