NovaStar MRV412-S Receiving Card Overview
The NovaStar MRV412-S is an LED display receiving card with 12 standard HUB75E connectors and support for up to 24 groups of parallel RGB data. It provides image adjustment, cabinet mapping and diagnostic functions for configuring and maintaining an LED display.
For an 8-bit video source at 60 Hz, the maximum load per card is 512 × 512 pixels with PWM driver ICs or 512 × 384 pixels with common driver ICs. Use the limit that matches your module’s driver IC when planning cabinet resolution.

Display Quality and Image Adjustment
- Color management and 18bit+: Support for standard and custom color gamuts, with grayscale enhancement for smoother images at low brightness.
- Pixel-level brightness and chroma calibration: Works with NovaStar’s calibration system to improve consistency across pixels. Calibration coefficients can be uploaded, read back, saved to hardware and erased.
- Seam and batch adjustment: Quick adjustment of dark or bright lines addresses brightness differences at module or cabinet seams. Multi-batch adjustment helps match brightness and chroma across production batches.
- Individual RGB gamma adjustment: Uses NovaLCT and a controller that supports this function to adjust red, green and blue gamma independently.
- Low latency: The receiving-card latency can be reduced to one frame when using modules with driver ICs that have built-in RAM.
- 3D and rotation: 3D output requires a controller that supports 3D. Rotation in 90° increments is supported; rotation at arbitrary angles requires the dedicated MCTRL R5 controller and SmartLCT software.
Cabinet Mapping, Diagnostics and Backup
Data Group Mapping displays test patterns by data group, while Mapping 2.0 helps identify cabinet positions and wiring. A stored image can be configured for startup, Ethernet disconnection or loss of video signal.
Temperature and voltage monitoring, bit-error detection and Ethernet-disconnection detection help diagnose operating and communication issues. The cabinet LCD function supports display of receiving-card status information. Firmware and configuration-parameter readback support maintenance, alongside loop backup, dual configuration-parameter backup and dual program backup.
Check Your LED Cabinet Before Ordering
Confirm the exact receiving-card model, module HUB75E wiring, driver IC, cabinet resolution and controller configuration before selecting a replacement. The MRV412-S load limits above are specified for 8-bit video at 60 Hz; they should not be treated as unconditional limits for every display setup.
This listing is for the MRV412-S. When comparing NovaStar MRV412 receiving cards, verify the complete model suffix: a similar model name alone does not establish replacement compatibility. For selection help, contact us with your existing card label and module details, or browse our LED receiving cards.

Frequently Asked Questions
How many HUB75E connectors does the MRV412-S have?
The MRV412-S has 12 standard HUB75E connectors and supports up to 24 groups of parallel RGB data.
What is the maximum resolution per receiving card?
With an 8-bit video source at 60 Hz, the maximum is 512 × 512 pixels with PWM driver ICs or 512 × 384 pixels with common driver ICs.
Does the MRV412-S support calibration?
Yes. It supports pixel-level brightness and chroma calibration with NovaStar’s calibration system, as well as calibration-coefficient management and uploading.
What equipment is needed for free-angle rotation and 3D?
Free-angle rotation requires the MCTRL R5 controller and SmartLCT software. For 3D output, use a controller that supports the 3D function.
Can I replace another MRV412 model with the MRV412-S?
Confirm compatibility before replacing it. Check the full model label, module wiring, driver IC, resolution and controller configuration; the shared MRV412 name is not enough to verify a replacement.
