- Avoid overloading circuits
Step 4: Connect Signal System
- Connect receiving cards inside cabinets
- Connect sending card to control system
- Use Ethernet or fiber cables
Step 5: System Configuration
- Install LED control software
- Set screen resolution
- Map cabinet layout
Step 6: Testing & Calibration
- Turn on system
- Check brightness and colors
- Adjust uniformity
- Test video playback
