Windows 10: Night Light (Night Mode) breaks on main monitor after waking up from sleep :( 1909 (fresh...

Hey there, I got a dual monitor setup, an AMD gpu with the latest drivers and for some reason night light always breaks/stops working on my main monitor (turning it on/off) doesn't do anything on the main monitor, it does work as intended on the second one though

I already tried desintalling the monitor under device manager, though that still doesn't help.

All help is appreciated

Windows 10 1903 (may update) Breaks Night Light (built in night light mode)

Hi there,

I have 2 machines (1 was an upgrade install to 1903 the other was a clean install). Both nvidia cards, 1080ti and a 2080 in the other (1 has the latest nvidia drivers the other has the very last version prior to the latest). Both intel 8700k processors.

what is happening: i keep the night light mode always on, and prior to 1903 (when i was using 1809), when i play a game (full screen) the nightlight mode would turn off in game. when i alt tab to windows, night light was enabled. when i jumped back into
a game, it was disabled. no issues.

when i upgraded to 1903 (both the clean install machine and the upgrade), when i have night light on, and go in game and alt tab, the night light remains off in windows, this never happened in 1809.

not limited to games, but in both machines using 1903, sometimes when i start the computer, the night light mode is disabled. trying to turn it on does nothing, and rebooting fixes it. but if happens enough now where i suspect this is not a one off, and
the fact it happens on both my computers, and when i go back to 1809 there are no issues.

i also tried flux, but it did the same thing where it would sometimes when you turn on the computer be off, and no way to enable it without rebooting.

lastly, i noticed when the display goes to sleep (the monitor, not the computer), night light is disabled. You can turn it back on, but the monitor being put to sleep effectlivley disabled night light mode from running on 1903, but not on 1809.

somehow i think this is all connected, something in 1903 with night light mode is not working properly like it did in 1809.

computer stats:

Machine 1 (upgrade to 1903):

• 8700k
• 32gb ram
• 970 evo 1tb
• nvidia 2080 FE
• nivida driver 425.31
• monitor asus 32inch running at 75hz (non-gsync)

Machine 2 (clean install to 1903):

• 8700k
  
• 32gb ram
• 970 pro 512gb
• evga 1080ti hybrid FTW3
• nivida driver 430.39

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

Turn off blue-emitting light so you are more likely to sleep/be able to sleep.



It's a blue light filter. It causes your display use warmer colors at night to help you sleep better and reduce eyestrain. It works just like Night Shift on the iPhone and Mac, Night Mode on Android, Blue Shade on Amazon’s Fire tablets, etc.
