Conflicting Programs

Este conteúdo não está disponível em sua língua ainda.

Only one RGB program can reliably control your devices at the same time. If another RGB application is running, SignalRGB won’t be able to take control — and will warn you when it detects a conflict.

Why Conflicts Happen

RGB software works by requesting direct access to your hardware’s lighting controls. When two programs try to claim the same device, one wins and the other gets blocked.

This causes issues like:

Devices not lighting up
Flickering or rapidly changing colors
Devices showing the wrong colors
SignalRGB not detecting devices at all

Resolving a Conflict

For occasional use, closing the conflicting program is usually enough. For consistent use of SignalRGB, uninstall it or disable it from launching on startup.

If SignalRGB detects a conflict on launch, a popup lists the active programs. You can close them from there or manually through Task Manager.

Known Conflicting Programs

ASUS — Armoury Crate / AURA Sync

Armoury Crate and its companion service AURA Sync claim exclusive control over ASUS hardware including motherboards, GPUs, and peripherals. The background service continues running even when the app is closed.

ASRock — Polychrome RGB

Polychrome RGB controls ASRock motherboard RGB headers and SMBus devices. Its service can persist in the background after closing the app.

Corsair — iCUE

iCUE runs a persistent background service that maintains exclusive control over all connected Corsair devices. Closing the iCUE window does not stop the service.

Cooler Master — MasterPlus+

MasterPlus+ controls Cooler Master peripherals and RGB accessories. Its background process can block SignalRGB from accessing the same devices.

Gigabyte — RGB Fusion 2.0

RGB Fusion 2.0 controls Gigabyte motherboard and GPU lighting over SMBus. It runs a background service that can interfere even when the app is closed.

Logitech — G Hub / Logitech Gaming Software

G Hub and the older Logitech Gaming Software (LGS) both claim exclusive control over Logitech peripherals. Both run background services that persist after the app is closed.

MSI — MSI Center / Mystic Light

MSI Center (formerly Dragon Center) includes Mystic Light for RGB control of MSI motherboards, GPUs, and peripherals. Its SDK service can block SignalRGB from accessing the same hardware.

Fix MSI Conflicts

NZXT — CAM

NZXT CAM is primarily a system monitoring tool but includes RGB control for NZXT hardware. It is not an obvious RGB app, but it can conflict with SignalRGB on any connected NZXT device.

Razer — Synapse 3 / Synapse 2

Razer Synapse runs background processes that maintain exclusive control over all connected Razer devices. Synapse 3 and Synapse 2 are separate programs that must each be handled independently.

SteelSeries — GG / SteelSeries Engine

SteelSeries GG (and the older SteelSeries Engine) controls SteelSeries peripherals. Most issues can be resolved by closing the app, though the background service may need to be stopped manually.

Windows — Dynamic Lighting

Windows Dynamic Lighting is a built-in Windows 11 feature — not a third-party app — that lets Windows control RGB devices directly. It runs automatically and can silently override SignalRGB even when no other RGB software is installed.

Unlike the apps above, you don’t uninstall Dynamic Lighting. You set SignalRGB as the priority app in Windows settings instead.
