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
