Why is my Night Light greyed out?
This often happens if your display driver is outdated or if you are using a third-party monitor driver that overrides Windows settings. Ensure your GPU drivers are updated via Device Manager. If you use a docking station, the hardware may not support the Windows color temperature API.
Does Night Light affect screen recording?
Yes, Night Light is applied at the system level. If you record your screen while the filter is active, the resulting video file will reflect the warmer, orange-tinted colors. If you need accurate colors for a recording, turn off Night Light before you start capturing your screen.
Is Night Light better than third-party blue light filters?
Windows Night Light is built into the operating system, making it more stable and resource-efficient than third-party apps. It integrates directly with your display drivers. Third-party filters can sometimes cause performance lag or conflicts with full-screen games, whereas the native Windows feature is optimized for system performance.
