NovaStar MSD300 / MCTRL300 LED Display Sending Card — M3 Series 1.3 Million Pixel DVI Controllers & Standalone Sending Box with Dual Ethernet & Audio
The NovaStar M3 series LED display sending card & controller box is available in two configurations — the LED display sending card / box (bare card for integration into sending boxes) and the MCTRL300 standalone sending box (independent controller with built-in power supply and metal housing). Both deliver identical 1.3 million pixel loading capacity, DVI video input, dual Gigabit Ethernet output with hot backup, audio transmission, and USB cascading control for professional GOB LED display systems. Supports resolutions: 1280×1024@60Hz, 1024×1200@60Hz, 1600×848@60Hz, 1920×712@60Hz, 2048×668@60Hz. Certified CE/RoHS/EAC/FCC/IC.
What Is the NovaStar M3 Series LED display sending card / box?
The NovaStar M3 series represents NovaStar’s foundational line of professional LED display control systems, designed for reliable, cost-effective signal distribution in rental LED displays, fixed installation LED displays, and commercial advertising screens worldwide. The series is offered in two form factors to match different installation requirements: the MSD300 LED display sending card — a compact bare card designed for integration into third-party sending boxes or custom LED cabinet designs — and the MCTRL300 sending box — a fully independent controller housed in a rugged metal enclosure with built-in AC power supply, ready for immediate deployment without additional hardware.
Both models share identical core processing capabilities, delivering 1.3 million pixel loading capacity distributed across dual Gigabit Ethernet output ports (650,000 pixels per port), DVI video input, 3.5mm audio input, USB Type-B control, and UART cascading for multi-unit synchronization. Developed by NovaStar, the world’s leading LED display control manufacturer, the M3 series LED display sending card / box has become one of the best-selling controller platforms globally, trusted by thousands of installations across 90+ countries for applications ranging from concert stages to corporate boardrooms.

Which one should you choose? Select the MSD300 LED display sending card if you are building custom LED control systems, integrating into existing sending boxes, or manufacturing LED display cabinets with built-in control modules. Choose the MCTRL300 LED display control box if you need a ready-to-use, standalone controller for rental LED displays, live events, or installations where rapid deployment and independent operation are priorities. Both deliver identical video processing performance, resolution support, and control capabilities.
LED display sending card / Box – 1.3 Million Pixel Loading Capacity — Power Meets Precision
At the heart of both the MSD300 LED display sending card and MCTRL300 LED display sending box is their impressive 1.3 million pixel loading capacity, distributed across two independent Gigabit Ethernet output ports with 650,000 pixels per port. This substantial processing power enables the M3 series LED display sending card & Controller box to drive a wide range of display configurations without compromising image quality or refresh rate stability. Both models natively support multiple standard resolutions optimized for different aspect ratios and application scenarios:
- 1280×1024@60Hz — Ideal for indoor LED displays and meeting room video walls with 5:4 aspect ratio
- 1024×1200@60Hz — Perfect for portrait-oriented digital signage and LED poster displays
- 1600×848@60Hz — Optimized for wide cinematic stage LED screens and broadcast monitors
- 1920×712@60Hz — Ultra-wide format for stadium perimeter displays and highway LED billboards
- 2048×668@60Hz — Maximum width configuration for panoramic LED video walls
Beyond these preset resolutions, both models also support custom resolution configurations with a maximum width of 3840 pixels (3840×600@60Hz) or maximum height of 3840 pixels (548×3840@60Hz), providing exceptional flexibility for non-standard display designs and creative LED installations. Both models accept progressive scan signals only — interlaced signals are not supported — ensuring clean, flicker-free output for professional applications.
Dual Ethernet Output with Hot Backup — Zero-Downtime Reliability
A standout feature of the M3 series LED display sending card / Control box is its dual Gigabit Ethernet output architecture with built-in hot backup redundancy. Each RJ45 port can independently drive up to 650,000 pixels, and in the event of a cable failure or port malfunction, the system automatically switches to the backup path without interrupting the display. This failover capability is essential for mission-critical applications such as security monitoring centers, live event LED walls, and broadcast studios where even a momentary signal loss is unacceptable.
The dual-port design also enables expanded signal distribution for larger LED video walls. By connecting each port to a separate chain of MRV series receiving cards, the M3 series can effectively double the horizontal span of the display without requiring additional sending hardware. This scalability makes both the MSD300 LED display sending card and MCTRL300 controller box cost-effective solutions for growing fixed installation LED displays that may need to expand over time.
Integrated Audio Transmission — Synchronized Sound & Vision
Unlike many basic LED controllers that handle video only, both the MSD300 LED display sending card and MCTRL300 LED display sending box feature a dedicated 3.5mm audio input jack that enables synchronized audio transmission alongside video signals. The audio data is embedded into the Ethernet output stream and can be extracted at the receiving card level for playback through external amplifiers or powered speakers. This integrated audio capability eliminates the need for separate audio distribution systems, simplifying installation and reducing cable clutter in conference room LED displays, retail advertising screens, and entertainment venues.
USB Control & UART Cascading — Scalable Multi-Display Management
Both models communicate with the host PC via a Type-B USB port, providing a stable, high-speed control channel for configuration, firmware updates, and real-time monitoring through NovaStar’s NovaLCT software. For larger installations requiring multiple controllers, both the MSD300 LED display sending card and MCTRL300 sending box support cascading of up to 20 units through their dual UART ports (IN and OUT), enabling unified control of complex LED video wall arrays from a single computer without additional control hardware.
This cascading architecture is particularly valuable for rental LED display companies managing multi-screen setups at concerts, trade shows, and corporate events, where rapid configuration and synchronized playback across dozens of display cabinets are essential. Each cascaded unit can be individually addressed and configured, allowing technicians to customize resolution, brightness, and color settings for different zones of the display while maintaining overall system coherence.
Pixel-Level Calibration Technology — Perfect Color Uniformity
Working in conjunction with NovaLCT and NovaCLB calibration software, both the MSD300 LED display sending card and MCTRL300 sending box support next-generation pixel-level brightness and chroma calibration. This advanced process measures the light output of each individual LED pixel across the entire display, then generates correction coefficients that eliminate brightness variations and color shifts between adjacent modules. The result is a perfectly uniform image with consistent brightness and chromaticity from edge to edge — critical for high-end fine pitch LED displays, GOB LED screens, and broadcast-quality video walls where viewers are positioned close to the display surface.
Ambient Light Sensor Integration — Intelligent Brightness Control
Both models of LED display sending card & Control box include a dedicated light sensor connector that enables integration with external ambient light sensors (such as the NovaStar NS060). When connected, the system automatically adjusts display brightness based on real-time environmental lighting conditions — increasing output in bright daylight for outdoor LED billboards and reducing intensity in dimly lit indoor venues. This intelligent brightness management not only improves viewer comfort and visibility but also significantly extends LED module lifespan and reduces power consumption, delivering long-term operational cost savings.
