Dynamic Lighting
On this page
Recommendation
SituationalDisable it if the manufacturer’s proprietary app already controls the lighting, or if lighting is not needed.
Do not run several RGB controllers at the same time: the conflict matters more than the toggle itself.

What changes
Section titled “What changes”Dynamic Lighting is a built-in Windows 11 feature for compatible RGB devices (keyboards, mice and other peripherals with lighting). It synchronizes Windows and apps with lighting devices: it controls color, brightness and effects, including coordinated lighting of devices from different brands.
The BoosterX setting disables this feature. RGB devices fall back to their default behavior without control from Windows — according to Microsoft documentation, devices continue to work with their standard, non-dynamic behavior. In practice, the manufacturer’s proprietary app (or the device firmware’s own mode) takes over the lighting again.
Exceptions and differences
Section titled “Exceptions and differences”The setting applies to Windows 11 only — in Windows 10 it is hidden. The standard location of the toggle: Settings → Personalization → Dynamic Lighting. The main practical conflict is two controllers at once: if Windows and a proprietary app (Armoury Crate, Synapse, iCUE and similar) control the same lighting simultaneously, the colors change twice and “jump”. Choose a single source of control.
How to verify the result
Section titled “How to verify the result”Set the lighting color in the manufacturer’s proprietary app: after disabling, Windows no longer overrides it with its own effect.
How to change and revert
Section titled “How to change and revert”Open Optimization → Customization → Visual effects → Dynamic Lighting and set the toggle to “On”: BoosterX will apply the disabling of Dynamic Lighting. Click “Apply” at the bottom of the page; if “Instant apply” is enabled, a separate button is not required. To revert, set the toggle to “Off”: BoosterX will return Windows to its standard state (Dynamic Lighting enabled).
