LED Receiving Cards: Functions, Compatibility and Selection
What is an LED receiving card?
A receiving card transfers mapped display data to LED modules inside a cabinet. It is a different component from a video processor, sending controller or local-media player. Selection depends on the sending system, output loading, cabinet mapping, physical connectors and operating constraints

Receiving Card Selection Checklist
The table below is a selection and verification framework, not a fixed product BOM or a guarantee of compatibility. Confirm the proposed configuration and project conditions before final approval.
| Parameter | Synchronous workflow | Failure if overlooked |
|---|---|---|
| Pixel load | Cabinet pixel dimensions and receiving-card capacity | Unsupported total pixels or split layouts |
| Module interface | Hub board, connectors and scan configuration | Mismatch can cause black or incorrect output |
| Calibration | Coefficient workflow and controller software | Replacement may require mapping and calibration recovery |
| Redundancy | Exact receiver and sending-path capabilities | Dual cards alone do not guarantee automatic failover |
How receiving cards work in an LED system
A sender or integrated controller delivers display data to receiver cards; the receiver card distributes signals to the module-level electronics. Hardware and configuration files determine which pixels and scan methods are addressed.
What to compare before choosing a card
Consider supported pixel load, data ports, system protocol, scan configurations, backup pathways, form factor, firmware and service support. A larger pixel capacity is not by itself evidence of universal compatibility.
Common receiving-card brands and families
NovaStar receiving-card lines (including A8s/A10s and MRV families), Colorlight receiving cards and Huidu HD-R families are possible vendor research paths. Refer to current official product sheets to compare exact model attributes; naming them does not mean all can be interchanged.
For detailed configuration and compatibility, consult the relevant linked technical guide listed in the internal-link implementation table.

Selection versus configuration
This guide covers which receiving-card capabilities to request. Mapping and loading a cabinet configuration belongs in the dedicated Receiving Card Configuration & Mapping guide, while redundancy principles remain with the existing Control Systems guide.
Practical selection checklist
Confirm the buyer’s purpose, screen dimensions and effective pixel count where applicable, required input/management features, environmental conditions, and the exact system-level performance that will be accepted at handover. Avoid treating model names or a supplier’s catalog rating as blanket compatibility or guaranteed field results.
