Colors off on the external screen

I connect my MBP 14 to an external screen. MBP -> Lenovo docking station -> Samsung screen. About 50% of the time everything works fine. However, for the remaining 50%, the colors are what you see in the attached photo. What are the first steps towards diagnosing the problem? Is this likely software or hardware?

MacBook Pro 2017 – screen color problem The problem occurs on the 13-inch MacBook Pro 2017 2.3 GHz Dual-Core Intel Core i5. The screen has lost its original colors for several days. It is like if some accessibility feature is running or if the problem is with the graphics drivers. The differences can be seen especially in people's faces, but in other places the colors are also wrong. I haven't changed anything in the macOS settings. I also reviewed all the screen settings and accessibility - all of them are in factory settings. I suspect the problem is with the hardware. Even larger pieces of the image can be seen with stronger deflection of the screen. I would like to add that the problem is not visible when using an external screen via a wireless connection on Apple TV.
