Posted July 4, 2018 So i have this issue with Windows 10 where, on my secondary monitor, night light gets activated while being turned off. It also doesn't apply to everything. Look at the screenshot i added to get an idea of what i'm talking about. For some reason turning on HDR/WCG fixes it. So at this point not really a problem but more of a curiosity. I'd like to hear what you guys think of this.

Posted July 4, 2018 Author Funnier even is that if i move a window from my secondary monitor to my main monitor, as long as more than half of the window is on the secondary screen, the window gets night light on both monitors. When i do the same thing but more than half of the window on main monitor the window is normal on both monitors. So yeah, Windows, buggy as usual Link to comment https://linustechtips.com/topic/944213-weird-night-light-behavior/#findComment-11502176 Share on other sites More sharing options...

Posted July 4, 2018 Sounds like Chrome is trying to use a faulty Color Calibration file, if you were to ask me. Start > type: Color > pick: Color Management In it, pick your monitor from the drop down list, check the box "Use my settings for this device" if it is not check already, pick the color profile, hit Remove, then press "Add" and select sRGB one, and OK. Restart Chrome. Link to comment https://linustechtips.com/topic/944213-weird-night-light-behavior/#findComment-11502561 Share on other sites More sharing options...

Restart Chrome. You are absolutely correct! Changed to a sRGB one, restarted Chrome, and it was fixed with HDR turned off. Strange that it only became a problem after i updated 1803. Guess we can count this as solved In case you were wondering, the file it was using was the Samsung Natural Color Pro 1.0 ICM profile which has my monitors model name as file name. Monitor is a Syncmaster XL2370, file name is SMXL2370.icm. Using sRGB IEC61966-2.1 now.
