One monitor has an orange tint while the other does not My macbookpro is connected to two external monitors.
The monitors are Dell U2715H

However somehow on one of the monitors looks like the night shift is turned on, and the other are not.


If I tried toggling the night shift setting, the orange tint just
switches screen.

I have tried unplug and plug. The effect stays the same.

I have tried the built-in monitor and fiddled brightness and
contracts settings. No effect. There is also not other color
temperature options.


Is there anything I can do to fix it without restarting the machine?
It is a 'MacBook Pro (15-inch, 2017)' running 10.14.6
The mismatch is fixed after a reboot.
