How this product solves common problems Reduces installation complexity by supporting most driver ICs and common scanning modes, which minimizes compatibility troubleshooting and speeds deployment. Eliminates content delivery delays by enabling program import via multiple interfaces including WiFi and U disk, so updates can be applied on site or remotely. Improves camera compatibility and recorded output through refresh rates and fine grayscale control, preventing flicker and banding in broadcast and livestreamed events. Simplifies multipanel and largescale projects by supporting up to 650000 pixels and standard maximum horizontal and vertical dimensions, enabling predictable layout and planning. Practical applications Live events and concerts: drive large stage LED walls with refresh and grayscale performance to ensure smooth motion and accurate color when captured by professional cameras. Retail and advertising displays: manage dynamic video, animation, and mixed content remotely over the network for timely promotional updates across instore screens. Control rooms and command centers: integrate diverse content types including images, video, and document data while maintaining clear, flicker displays for critical monitoring. Performance and compatibility notes Designed for professional LED installations where pixel counts, versatile content support, and camerafriendly refresh rates are required. Compatible with a wide range of LED modules thanks to support for most driver ICs and both real and virtual pixel scanning modes. Maximum horizontal resolution 1920 pixels and vertical resolution 1080 pixels must be observed when planning screen layout. Summary This Color L4 controller dimmers unit is a flexible, performance LED screen controller built for large displays and professional use. It offers multiple import options, broad media and hardware compatibility, advanced grayscale and refresh capabilities, and networkbased configuration to streamline installation, operation, and content management.
