The Realtek DMFT - RGB (Realtek Digital Media Functionality and RGB) driver is associated with Realtek's software and hardware components that handle the RGB lighting and digital media functions on some motherboards and peripherals. It is commonly bundled with Realtek audio or motherboard drivers, but it may be specifically tailored to manage RGB LED lighting effects on motherboards, soundcards, or other devices that feature customizable lighting.

This driver is often seen in motherboards with integrated Realtek audio chips and RGB lighting control, where it enables the control and synchronization of RGB lighting effects on various connected devices.
