Windows 10: Display Tint Change akin to night light after desktop loads - Windows 11, 23H2, ACER Swift...

My laptop persists in an issue after login, whose symptoms are as follows:- Upon booting my Windows 11 Partition, my desktop loads normally. The first 10-15 seconds, my display is vibrant with overall 'cool' colors.- After about 15 seconds, while other software are starting up - Steam, Google Drive, etc., the display snaps into a distinctly warmer, orange-red tint. It reminds me of Night Light/similar eye protection color tones, despite these being disabled on my machine.This issue does not persist on Linux partitions. What diagnostics might I perform to identify which processes or drivers

Night Light problems

• Click start and then settings.
• Click system.
• Click Display.
• And you'll find night light there.
• And if u want to change the color click night light settings.

 

Can't find night light mode in display.

Hey guys,

I just got this HP windows 10 laptop, and I tried to enable the night light function to help filter the blue light to protect my eyes from getting sore. I followed every steps online, "setting-display-night light mode"..but I reached to the "customize your display" instead of "display", and there's no such a thing called "night light"(pic shown as below). I would appreciate if you can help me with this problem, bring me back to the normal display setting to get my favourite night light turned on. Thank you!

 

Windows 10 night light color not returned when mode turned off

I have a dual monitor setup I just upgraded to identical Samsung monitors and a single AMD Radeon RX580 graphics card. I also have two computers hooked up to both.

After installation I had one monitor input from a laptop and the second monitor input from a desktop. Everything was great. It was late and on the desktop I wanted to try night light. I set it adjusted and adjusted the color tint. Everything was great but decided I did not like it. I shut off night light but the display never returned to the default brightness setting the other monitor still has.

Before trying sleep mode the monitors did have the same color warmth.

Both monitors are connected to the card using same brand display port cables. Prior to trying the night light the color warmth appeared the same.

When both monitors are using the desktop input in extend display mode there is a distinct tint difference between them. The monitors are side by side with the only gap between them the edge bezel. I am using the mostly white Windows settings application window to compare. When I position it to cross both monitors the monitor I tried night light on is definitely warmer with a less blue in it.

Both the computer and monitors have been powered off and no change.

What I have checked/attempted so far without resolution:

• Reset both monitors to default settings even though I never changed their settings. I have compared all the internal monitor settings for color tint/hue/etc. and they are the same.
  
• Using the AMD Radeon settings software I have reset both displays color management to default even though they were the same.
  
• In Windows display settings confirmed the night light setting is off for both displays. Just in case there is some bug still using the night light warmth setting both displays are set all the way to the right.
  
• In Windows display setting compared every setting I can see between the display and they are both exactly the same.
  

I have looked for some higher level display or graphics setting or properties settings that could explain it but I can't find anything.

Help? I am a fairly experienced PC user but I have reached the end of what I know to check.

If it would help to see a picture of the warmth difference I can provide one.
