You need a NovaStar MRV412-N. You need accurate specs for planning, reliable setup advice to avoid errors, and a trustworthy source to get it. This page delivers all three.
1. What is the NovaStar MRV412-N?
The NovaStar MRV412-N is a workhorse receiving card that turns video data into a picture on your LED wall. It’s the critical link between your video processor and the actual LED modules.
Here’s what that really means for your job:
For Project Planning: You need its physical specs. It measures 145.6mm x 91.5mm, with a total thickness of ~20mm. You must check for clearance in your cabinet design. It runs on 5V and draws about 2.5W, which you need to factor into your power supply calculations.
For Buying: Its value isn’t in the chip itself, but in the software features it unlocks. Pixel-level calibration is the main reason you choose this over a cheaper card. It’s the tool that fixes color mismatches between modules, saving you from ugly, patchy screens and unhappy clients.
For Installation: This card has 12 HUB75E outputs to drive your modules. It has two Ethernet ports for a redundant loop—if one cable fails, the data flow automatically reverses to keep the screen online. The status LED and self-test button are your first tools for troubleshooting a blank section of wall.
MRV412-N is a reliable, functional component chosen for projects where the display absolutely cannot look wrong. Its job is to make your installation look professional and stay running.
2. Key Features and Benefits
These are NovaStar MRV412-N core functions and how they solve practical problems on your projects.
2.1 Pixel-Level Calibration
Factory LEDs vary slightly. This feature measures and adjusts the brightness and color of every single LED. The result is a perfectly uniform display without color patches or bright spots. It is standard for high-end installations where visual consistency is non-negotiable.
2.2 18bit+ Processing
This allows the card to process more grayscale data. On screen, this creates smoother color gradients and eliminates flickering and banding artifacts, particularly at lower brightness levels. It makes content like sunsets or shaded graphics appear much more realistic.
2.3 Color Management
Support for Rec.709 and DCI-P3 color spaces lets you match your LED wall’s output to other professional monitors or projectors on-site. This provides accurate color reproduction from the start, ensuring the reds, greens, and blues match the content master.
2.4 Low Latency Mode
Activating this mode reduces video delay to a single frame. This function is necessary for live broadcasts or interactive applications where even a slight lag is problematic. Note: This requires driver ICs with built-in RAM.
2.5 90° Image Rotation
This feature corrects the image orientation when a module must be physically mounted sideways. It removes the need for hardware rework, saving significant time during installation and troubleshooting.
3. Full Technical Specifications
| Specification | Detail | Why It Matters to You |
| Max Resolution | 512×512 @ 60Hz (PWM ICs) 512×384 @ 60Hz (Common ICs) | Defines how many pixels one card can drive. Don’t overload it. |
| Data Outputs | 12 x HUB75E connectors (24 groups RGB data) | Determines how many modules or cabinets you can chain from one card. |
| Power Input | 5V DC | You need a stable 5V power supply. Voltage drop will cause problems. |
| Typical Power Draw | ~2.5W | Crucial for calculating your total power budget and PSU size. |
| Operating Temp | -20°C to +70°C | Confirms it’s fit for purpose in most indoor and protected outdoor environments. |
| Certifications | RoHS, EMC Class A | Necessary for commercial sales in many regions. Don’t ignore this. |
| Dimensions (LxWxH) | 145.6mm x 91.5mm x ~20mm | The height is critical. Must check clearance in your cabinet design. |
4. NovaStar MRV412-N Setup Tips
Okay, you’ve got the MRV412-N NovaStar. Here’s how to not mess it up.
Power First, Data Second: Always connect the power cables securely before you plug in the Ethernet. And use the right gauge wire. A poor power connection is the root of all evil in LED displays.
Listen to the Lights: The status LED tells a story. A green flash every second? Good. Everything’s happy. Flashing fast three times? It’s getting data but no video signal. Check your controller output. A flash every three seconds? That’s a network problem. Check your cables.
Use the Test Button: Can’t get a signal? Don’t panic. Disconnect the Ethernet cable and hit the self-test button on the card twice. The screen should light up with a test pattern. This tells you if the problem is upstream (controller, cables) or right there with the card and modules.
Double-Check Your Rotation: If the image looks sideways, you probably just forgot to set the rotation in the software. It’s an easy fix. Don’t start remounting hardware until you’ve checked this.
5. Price & Where to Buy MRV412-N
A single NovaStar MRV412-N unit typically carries a street price around $14 USD. This is a baseline for budgeting. For project quantities, expect volume discounts that lower the per-unit cost.
