Question: Why is my LCD display not functioning properly after installing SignalRGB? (6/30/2026) Answer: Polychrome Display and SignalRGB should not be installed or running on the same system at the same time. Both applications may attempt to communicate with the LCD controller simultaneously, which can result in:
- LCD display abnormalities
- Software instability
- Communication errors
For the best user experience, please install only one software at a time.
• If SignalRGB is installed, please uninstall Polychrome Display before use.
• If wish to use Polychrome Display, please uninstall SignalRGB and restart your system before use.
