What Matters When Selecting KU20
COEX Workflow
Current COEX systems use VMP and supported receiving cards. Advanced display features depend on the controller, receiving card and LED driver IC working as a compatible system.
Migration
Moving from an older NovaStar controller to COEX can be a platform migration rather than a simple box replacement. Check receiving cards, firmware and configuration workflow.

Project checklist
Before Buying or Replacing KU20
Screen Resolution
Record total width × height, cabinet resolution and Ethernet-port mapping.
Receiving Cards
Identify the exact receiving-card model, hub board and current configuration file.
Video / Content Source
List the required video connectors or publishing method instead of assuming another model has the same inputs.
Software & Firmware
Match the controller/player generation before upgrading firmware or configuration software.
Replacement Goal
Decide whether you need a drop-in spare or a platform upgrade with new features.
Backup
Keep mapping, receiving-card parameters, firmware information and photos before service work.
