Windows 10: Deskop automatically dimming after turning on/off night light

Summary of issue:Someone tapped on a bunch of keys today on my keyboard, over on the right hand side prt sc, pg up, ins, del, etc. They don't know which keys they hit, but it dimmed the screen of my desktop down to what seems like minimum brightness.

Night Light doesn't automatically turn off in the morning

Hi,

Tried out the methods in comments sections but problem still exists. Here, is what i have noticed.


SCENARIO 1.

Night light set ON time 2100 HRS and OFF at 2115 HRS.

1.if the computer is ON @ 2115 HRS night light turns off automatically. (correct)
2. If the computer is shutdown @2110 HRS and switched ON @ 2120 HRS. Night light is off at login. (correct)
2. if the computer was put to sleep @ 2110 HRS and resumed @ 2120 HRS, night light does not turn off. (incorrect).

Basically night light dosen't work properly after a sleep or hibernate happens.

 

windows 10 night light when on cycles dimming

I have windows 1903 Build 18362.329 installed on my desktop and I'm using the windows night light in the settings. Lately (not sure just when it started) I've noticed that when it is on about every 2-5 minutes I notice my monitors will dim just enough to
be very noticeable and then brighten to the night light level. The dimming/brightening is a gradual process (about a 10-second cycle) and is very annoying. If the night light is NOT on then the monitors do not dim/brighten. As a test, I turned the night light
off and installed f.lux (it is now on) so far it has not dimmed/brightened and it has been at least 30 minutes since f.lux turned on.

I've searched for a solution but so far I have not found a solution. Obviously I can stay with f.lux but I'm attempting to remove all software where windows provide the same function, assuming that the windows code is as good or better than the add-on.

My graphic card (NVIDIA GTX 470 Graphic Card) has the latest drivers from NVIDIA and were installed two days ago. Prior to the installation, I had the night light issue. I installed the latest drivers to see if that would resolve the issue.
