For best results all other RGB programs should be closed.
Ignoring these warnings is likely to lead to a wide range of device issues.
Due to the nature of RGB Software only one program can reliably control devices at the same time. Having multiple programs open will commonly lead to issues like flickering, stuck lighting, and unresponsive devices. Due to this SignalRGB won’t control devices if it detects a potentially conflicting program running.
You can tell SignalRGB to ignore this check on the device’s setting page, or preferably close the conflicting program. Most like Steelseries Engine or Razer Synapse can just be closed, but others will require background services to also be closed.
If you intend on using SignalRGB consistently these programs should be uninstalled or set to not launch on start up to prevent this issue reoccurring.
