Windows 10: Night light setting on 240hz monitor

Hey. There seems to be an issue when the Night Light setting is ON, only on the Alienware AW2518HF, scrolling the websites creates a greenish effect around the text.

Night Light Setting and Third Monitor.

Hi Reagan,

We would like to ask you some questions in order assist you properly:

• Did Night light work previously on all three monitors?
• Have you made any recent changes to your PC?
• Are you getting an error message on the third monitor regarding Night light?
• Is the third monitor being detected by your PC?
• What troubleshooting steps have you performed so far?

While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

Regards.

 

Night Light Settings

Separately from the Night Light, is the brightness options also disabled? If so, I might recommend these steps to make it work again:

1) Right-click Start button, choose Device Manager

2) Find the "monitors" section in the list and expand it

3) Right-click and uninstall every item listed under the monitors section

….. note: don't accidentally go to the "display adapter section", leave that one untouched.

4) Click the "scan for hardware" button on the toolbar up top (the icon with the magnifying glass inside it)

5) Try brightness and night light settings again

 

Windows Night Light always on for laptop monitor.

I did the steps you described, but the problem remained the same after doing so:

After reboot, the night light setting was disabled and there was no blue-light filtering, as it should be. However, as soon as I (dis)connect any external monitor, some blue-light filtering is applied to my laptop screen (although according to the settings,
night light is still off).
