Description
NovaStar MRV412-N Receiving Card Overview
The NovaStar MRV412-N LED receiving card is a general-purpose receiver card for LED display cabinets. It accepts 8-bit video sources and combines high loading capacity with image-quality, maintenance and reliability functions for fixed-installation, rental and other LED display systems.
With PWM driver ICs, one MRV412-N supports resolutions up to 512 × 512 @ 60Hz. With common driver ICs, it supports up to 512 × 384 @ 60Hz. The card uses 12 standard HUB75E connectors and supports up to 24 groups of parallel RGB data, making it suitable for a wide range of cabinet and module layouts.
Best for: LED display projects that need dense HUB75E connectivity, accurate color, low-latency options, practical monitoring and dependable backup protection.

Display Quality Features
- Color Management: Supports standard Rec.709, DCI-P3 and Rec.2020 color gamuts as well as custom color gamuts for more accurate on-screen color.
- 18bit+ grayscale enhancement: Improves LED display grayscale by four times, helping reduce grayscale loss at low brightness and produce smoother images.
- Pixel-level brightness and chroma calibration: Works with NovaStar’s high-precision calibration system to correct individual pixels and improve brightness and color consistency.
- Quick adjustment of dark or bright lines: Corrects visible seam brightness caused by module or cabinet splicing, with adjustments taking effect immediately.
- Multi-batch adjustment: Helps minimize brightness differences between cabinets or modules from different production batches.
- Low latency: Can reduce receiving-card-end latency to one frame when used with modules whose driver ICs include built-in RAM. This function is disabled by default and can be enabled when required.
- 3D output support: Works with a NovaStar controller that supports 3D to enable 3D output.
- Individual RGB gamma adjustment: With NovaLCT and a compatible controller, red, green and blue gamma can be adjusted separately to improve low-grayscale uniformity and white balance.
- 90° image rotation: Rotates the image in 90-degree increments for flexible cabinet orientation.
Maintenance and Monitoring
- Mapping 1.1: Displays the controller number, receiving card number and Ethernet port information on cabinets so technicians can identify card locations and connection topology.
- Stored image settings: A custom image can be shown at startup, when the Ethernet cable is disconnected or when no video signal is present.
- Temperature and voltage monitoring: Monitors the receiving card without requiring an external measurement device.
- Cabinet LCD support: A cabinet LCD module can show temperature, voltage, single-run time and total run time.
- Bit error detection: Monitors Ethernet-port communication in real time to help troubleshoot network communication issues.
- Firmware program readback: Reads the receiving card firmware program and saves it to a local computer.
- Configuration parameter readback: Reads and saves receiving card configuration parameters, improving setup and service efficiency.
Reliability and Backup Protection
- Loop backup: The receiving card and controller can form a loop through primary and backup line connections. If a line fault occurs, the screen can continue displaying normally.
- Dual backup of configuration parameters: Parameters are stored in both the application area and factory area, allowing the factory settings to be restored when necessary.
- Dual firmware backup: Two firmware copies are stored at the factory to reduce the risk of an abnormal interruption during a firmware update.
Compatibility and Selection Notes
The MRV412-N is a receiving card, not a sending card. It must be used as part of a compatible NovaStar LED control system. Actual loading capacity and available functions depend on the LED module driver IC, scan configuration, controller, firmware and NovaLCT setup.
Before ordering, confirm your cabinet’s HUB75E interface, driver IC type, required pixel load and feature requirements. Explore more LED receiving cards or view the complete NovaStar product range.
Typical Applications
- Indoor and outdoor LED display cabinets
- Fixed-installation LED video walls
- Rental and stage LED screens
- Broadcast, control-room and presentation displays
- Projects requiring calibration, monitoring, low latency or redundant signal paths
Frequently Asked Questions
What is the maximum resolution of one MRV412-N?
With PWM driver ICs, one card supports up to 512 × 512 @ 60Hz. With common driver ICs, it supports up to 512 × 384 @ 60Hz.
How many HUB75E connectors does the MRV412-N have?
It has 12 standard HUB75E connectors and supports up to 24 groups of parallel RGB data.
Does the MRV412-N support low latency?
Yes. Low latency can reduce the receiving-card-end delay to one frame when the LED modules use driver ICs with built-in RAM. The option is disabled by default.
Can the MRV412-N support 3D LED display output?
Yes. It can enable 3D output when paired with a controller that supports the 3D function.
Does it support display calibration?
Yes. The MRV412-N works with NovaStar’s high-precision calibration system for pixel-level brightness and chroma calibration.
Can it rotate the LED display image?
Yes. The image can be rotated to 0°, 90°, 180° or 270°.
