If you have devices like LED keyboards, mice, or case lights that support Windows Dynamic Lighting, you can easily adjust their brightness. This guide will show you simple steps to make your LED lights brighter or dimmer using Windows 11.

What is Windows Dynamic Lighting?

Windows Dynamic Lighting lets you control the lighting on your compatible devices, either one by one or all at once, through the Windows Settings app. Once your devices are connected, they show up as cards at the top of the settings page, where you can choose each device and adjust its light settings.

Why Adjust LED Brightness?
