Night Light is a very handy feature that is available by default in Windows 10 and Windows 11. Essentially, when you toggle it on, Windows reduces the emission of blue light from the display which in turn decreases the stress on eyes and can potentially aid in better sleep too. While this feature generally works quite well, this hasn't been the case so far on some Dell PCs.
Now, Dell has acknowledged the issue in a recently published support document. As the situation currently stands, Night Light does not work on the secondary display on certain Windows Arm PCs when an external monitor is connected to them. This happens on the following PC models:
- Inspiron 14 5441
- Inspiron 14 Plus 7441
- Latitude 5455
- Latitude 7455
- XPS 13 9345
Now, Dell has confirmed that this is not due to any hardware or software issue on its side, it's just a limitation of the Qualcomm Oryon chipset. In essence, this is a problem that is outside the control of Dell.
What this means is that while customers can utilize built-in and third-party tools to adjust the color profiles of their displays, Dell can't really get Windows Night Light to work as-is on external displays connected to any of the Arm PCs listed above.
The company has emphasized that there are no plans to support Windows Night Light on its existing Arm PCs, and that customers will just have to make do with what they have. However, this feature will likely work as designed with the "next generation" of Arm computers, which will presumably leverage a chipset that is not held back by this limitation. Windows on Arm has enjoyed decent support from software developers in recent times; Microsoft will be hoping that it can keep the momentum going with its next Snapdragon PCs.
