If you have LED lights on your keyboard, mouse, or PC case that work with Windows 11’s Dynamic Lighting feature, you can easily change how bright they shine. This guide will show you simple steps to make the lights brighter or dimmer to suit your comfort.

What is Windows Dynamic Lighting?

Windows Dynamic Lighting lets you control LED lights on devices like keyboards, mice, and PC cases that support this feature. You can adjust each device separately or all at once using the Windows Settings app.

When your LED devices are connected, they appear as cards at the top of the Dynamic Lighting page. Just click on a device’s card to change its settings.

By changing the brightness, you can reduce eye strain in dark rooms or just make your setup look the way you want, whether brighter or softer.
