How to Change LED Brightness in Windows 11 Dynamic Lighting
You change LED brightness in Windows 11 Dynamic Lighting through the device settings within the Windows 11 Settings app.
Windows Dynamic Lighting is a feature that allows you to control compatible RGB lighting accessories, like keyboards and mice, directly from your operating system. It uses the new Human Interface Device (HID) class specification for RGB keyboards and the HID Runtime Designer (HRD) to enable this centralized control.
This means you can adjust the brightness, and often colors and effects, for your supported hardware without needing individual manufacturer software. For example, you might find your Razer keyboard or Philips Hue smart lights integrate seamlessly.
You access these controls by navigating to Personalization > Dynamic Lighting in Windows 11. From there, you can select your devices and make your desired adjustments.
What is Windows Dynamic Lighting?
Windows Dynamic Lighting lets you control the lights on your compatible devices. You can adjust them one by one or all at once through the Windows Settings app. Once your devices are connected, they appear as cards at the top of the settings page. You can pick each device and change its light settings.
Why Adjust LED Brightness?
- Make your lights softer to reduce eye strain, especially in dark rooms.
- Make your lights brighter if you prefer more glow or want to see better.
