Windows 10: Screen Orange on one login -- it's not Night Light

Hi Everyone,


I did some research on this site but couldn't find an answer to my question.


I have two desktop logins to my Dell XPS 9550 -- two users. Logging in one produces a nice, normal laptop screen. Logging in the other produces an orange laptop screen. It's not night light -- night light is off. If I turn on night light, the screen becomes even more orange.


All drivers are fully updated, Windows 10 pro is fully updated. Very clean build with no extra software really. Virus scans show nothing. Well-kept machine with no obvious physical problems.



The only other bizarre behavior is when I close the laptop lid, the instruction is "sleep" in the control panels. But when I come back, the battery might be drained as if the computer were on. I could make a separate post about this.


Anyway, back to the orange -- because the computer works fine in the other login, I figure this is some kind of software issue, but poking around has not helped me.


Any ideas? Many thanks in advance,


Rishi

Night Light

Does anyone know how to turn off night light? when I try it says its off but my screen is orange.

 

No Night Light

Hi allisonb1

Try these steps

Option 1. Reset Night Light-related Settings on Windows 10 Fall Creators Update

If you find the night light in the Action Center or the Settings is greyed out after the Windows 10 Fall Creators Update, you can fix it with the steps below:

Step 1. Use Windows shortcut keys Win + i to open Settings.

Step 2. Go to the Privacy menu.

Step 3. On the left side, choose the Location tab.

Step 4. Click the Change button under the Location for this device.

Step 5. Toggle the switch under the Location for this device to ON.

Step 6. Toggle the switch under the Location service to ON.

Step 7. Restart the computer.

Now check the Action Center or the Settings on your Windows 10 Fall Creators Update to see if the night light feature is available.

Option 2 . Modify Registry to Fix Night Light Not Working on Windows 10 Fall Creators Update

If the methods above didn't work, you may need to modify the registry to fix the greyed-out night light button or the night light not working issue. Note: Windows Registry is a vital database on Windows OS computer. Any misoperation will cause server system
problems, such as 100% disk usage issue, blue screen issue, endless reboot, etc. So it's important to backup registry before the changes.

Now let's kill the night light not working and release the pain:

Step 1. Use Windows shortcut keys Win + R to launch Run.

Step 2. Type into regedit.

Step 3. Hit the Enter key.

Step 4. Copy and paste the path into the address bar of the Registry Editor: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount

Step 5. Press the Enter key.

Step 6. Right-click the key $$windows.data.bluelightreduction.bluelightreductionstate under the DefaultAccount and select the Delete to remove it.

Step 7. Right-click the key $$windows.data.bluelightreduction.settings and select the Delete.

Step 8. Restart the computer.

Then you can go to the Action Center or the Windows Settings. The night light not working issue has been resolved now and the night light button is available.

Screen color shifts to red after login, even with night shift off

Basically, problem is:

1. Screen display is neutral pre-login
2. Login and after 15-30 seconds, screen shifts to red, like night light is on
3. night light is off in the settings, turning it on can make it even more red
4. turning night light off again removes the extra color temp but not getting rid of it all the way

I've followed a number of posts on this issue, updating windows, turning off night shift, turning back on, checking that no monitor color profiles are turned on, etc. What I have found after experimentation though is that creating a new user on the computer
and loging in as that user does not show the red shift problem, which points to something in my profile.

What I can't figure out is what is that something?

Does anyone have suggestions on fixing a broken profile or resetting the setting that controls this?

Thanks!

Reference Post, which was a different problem, but where the 'new user' suggestion was given:

Screen color temperature changes after start-up (as if Night Light is enabled, though it isn't)
