Does Nightlight work on a second monitor? It works on my laptop but not the 2nd monitor

I have Windows 10 Nightlight to work on my Dell XP 15 laptop, but it does not extend to my 2nd monitor (I use both my laptop screen and a 2nd monitor when I am working).

Has anyone figured out how to get Nightlight to work on a second screen?

For me, it seems to be a compatibility problem with a connection you’re using. The best way to test would be trying to connect a second monitor directly to your laptop using HDMI, DisplayPort, mini DisplayPort, or DVI (maybe even VGA) to see if the hub connection is the problem.

Alternatively, you can also try Flu.x for Windows 10 to add a similar feature.
