Windows 10: Window Night Light Issue/ Light is now Green!

I just recently installed a RTX 2070 Super video card. I noticed the night light on my M50-C1 T.V. is now bright green.


The night light is fine on my PC Monitor. It is normally red.


I've been messing with the Nvidia Control Panel settings in an attempt to fix the problem.


So far, if I turn the Refresh Rate to 30hz, it allows the monitor to use RGB Output Color Format, which solves my problem!


But, when I change back to 60hz, it switches the Output Color Format to YCbCr420, and does not allow you to go back to RGB unless you return to 30hz.


I've also tried all other Refresh Rates, only works on 30hz


I've tried different resolutions, problem still exists.


My Display Driver is up to date.


At this point I'm not sure how to fix this. I've searched the web and it seems this problem isn't too common. Any help would be greatly appreciated!




Prior to switching Video Cards, I never had this problem.


My specs:

Motherboard: ASRock B450M Gaming

CPU: AMD Ryzen 5 3600

RAM: 8x2:16BG Corsair

Graphics: Geforce RTX 2070 Super EVGA

PSU: EVGA 600 Watt Plus Gold

Operating System: Windows 10 version 2004 most recent

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.
