Steps to reproduce the problem:
1. Attach an external monitor using HDMI - mine is
B326HK : Manufacturer: ACR - Product ID: 0410 - Year of Manufacture: 2017

Notice that the display looks fine.

2. Enable the night light flag - chrome://flags/#ash-enable-night-light

3. Restart Chrome OS.

What is the expected behavior?
The display should look the same as it does without the night light flag enabled.

What went wrong?
Now on the external monitor, you can hardly see anything with a white background, especially text. Everything appears "washed out".

Did this work before? Yes 67

Chrome version: 68.0.3416.0  Channel: dev
OS Version: 10635.0.0
Flash Version: 29.0.0.171

Only the external display is affected; the internal display looks fine.

Note that you don't need to actually turn on night light, just enabling the feature does this.
