Compatibility Checklist

Matching these points before ordering reduces wrong-selection risk.

HUB75 series module wiring check (HUB75E recommended)
Scan rate must match (1/16, 1/32, 1/64, etc.) to avoid mapping mismatch
Verify driver IC type (Conventional/PWM) according to your system
Set config file and mapping according to controller/processor brand and model

Installation & Commissioning

Following best practices reduces downtime and makes maintenance easier.

Label ribbon cables and power cables before installation
Ensure proper grounding and signal cable quality (reduces noise)
During commissioning, use test patterns to check dead pixels or line issues
Keeping a spare receiving card is recommended (rental/outdoor projects)

Common Issues & Quick Fix

During setup, most issues come from mapping, scan settings, or cable routing.

Display shifted/mirrored -> mapping/scan mismatch or HUB pinout mismatch
Random flicker -> grounding/signal noise or weak PSU
Half screen dead -> loose ribbon cable or port assignment mismatch
Wrong colors -> IC config / gamma / data polarity check

FAQs

Common questions about receiving card selection:

1Are receiving card and sending card the same?

No. The sending card/processor sends data from the content source, while the receiving card inside the cabinet receives data and distributes it to modules.

2What happens if I choose the wrong card?

It can cause mapping mismatch (shift/mirror), flicker, half-screen failure, and color issues-especially with scan/HUB mismatch.

3What information is needed for selection?

Provide module size/pixel pitch, scan rate, HUB type, cabinet resolution, and controller brand/model for quick and accurate matching.
