Only one app, either NGENUITY or OMEN Light Studio, can have control over the lighting of a device at one time. If OMEN Light Studio is currently controlling the lighting on your device, you can open the Lighting configuration page in NGENUITY to switch the control back to NGENUITY. Vice versa if NGENUITY has control. When both OMEN Light Studio and NGENUITY are installed, if you plug in a new HyperX device, the lighting will be controlled by NGENUITY by default.
Please note OMEN Light Studio *only* controls the device lighting. For compatible HyperX devices, any other configuration eg. key binds, DPI, etc. must be controlled via NGENUITY.
