Bad nuance of light and shadow

Hello, I'm having an issue on my new MSI GE62 2QF with the intel HD 5700 display. I don't know how can I describe it but... the nuances of light and shadow seem to be too pixelated it's not soft and harmonious.

Here are some examples:

I tested all the version of my intel drivers nothing corrected this.

If someone can help me. Thanks.
