I've only experienced this since I upgraded to 4K monitors. I've used DisplayLink adapters for a long time with non-4K monitors and haven't had the issue with them.

It's not a browser thing, or an application-specific thing. It applies to the entire display and to all applications: the desktop, Windows Explorer, Photoshop, Visual Studio, etc.

I've tried several different cables from different manufacturers.

Yes, it happens regardless of the resolution used. I'm currently using the native resolution on all monitors, but for example if I change the 4K monitors from 3840x2160 to 1920x1080, I still have the same color inversion on the DisplayLink monitors.

At this point I have three external monitors: Two Dell P2415Q units, and one Dell UP2414Q. I've tried all combinations of monitors and adapters, and as long as one monitor is connected directly to the laptop via DisplayPort, the ones connected via DisplayLink USB adapters exhibit the color inversion.
The only way to make the problem go away is to connect
all the external monitors using DisplayLink USB adapters. This is not ideal because the DisplayLink 4K adapters don't support a 60Hz refresh rate.
I haven't tried this with another laptop because I don't have one that has a DisplayPort jack.
Thanks for your help -
