Windows Night Light Support for External Monitors on an ARM Computer

Windows Night Light is a feature that reduces blue light emitted by your display, especially during the evening. This can help improve eye comfort and potentially aid in sleep. You can enable and customize Night Light in Windows 10 and 11 through the Settings app (under System and Display options).

When a Dell ARM-based (Qualcomm) computer is connected to an external monitor and Windows Night Light is enabled for the external monitor, there may be no change seen on the external monitor. Windows Night Light still works on the laptop’s screen when this occurs.

Affected Platforms:

• Inspiron 14 5441
• Inspiron 14 Plus 7441
• Latitude 5455
• Latitude 7455
• XPS 13 9345

A limitation of the Qualcomm Oryon chipset causes this.

This is a limitation of the Qualcomm Oryon chipset. Dell does not plan to support this feature within the current Dell ARM platforms. This feature is expected to be available with the next generation of ARM computers.

The Windows Night Light feature works only with the laptop’s LCD screen.

Workaround:

Dell monitors can use Dell Display and Peripheral Manager to adjust color presets. For more information about the Dell Display and Peripheral Manager application, refer to Dell Display and Peripheral Manager for Windows. To download Dell Display and Peripheral Manager, go to Support for Dell Display and Peripheral Manager - Drivers & Downloads.
