The AT30 is a general small receiving card developed by NovaStar. A single AT30 loads up to 512×256 pixels. Supporting various functions such as pixel level brightness and chroma calibration, quick adjustment of dark or bright lines, 3D, individual Gamma adjustment for RGB, and image rotation in 90° increments, the AT30 can greatly improve the display effect and user experience. The AT30 uses high-density conn ectors for communication to limit the effects of dust and vibration, resulting in high stability. It supports up to 32 groups of parallel RGB data or 64 groups of serial data (expandable to 128 groups of serial data).
