Wacky colours Chrome, new monitor Viewsonic vx4380

I bought a new monitor: 43" viewsonic vx4380-4k,

Good but had weird colors (blues appearing as greens), I noticed this was only in Chome (Version 68.0.3440.106 (Official Build) (64-bit)).

For example the google logo normally appears like this:

 Now appeared like this:

 The cause is the hardware acceleration, which can be turned off in chrome:

1. open the options menu which looks like a burger.  Drop down menu appears.
2. select settings, browser goes to chrome://settings
3. scroll down and click Advanced, advanced section opens.
4. Scroll down to System, turn off "Use hardware acceleration when available"

Hopefully this will be resolved in new Chrome or monitor drivers. 

Note "hardware acceleration" means using faster hardware rendering on GPU instead of slower software rendering on CPU.
