After a long research..

[d_k]

On NUC7i3BNK..

4K/ 60Hz with HDR no flickers at all!!

Solution?---> disable (or activate, doesn't matter just move from one place to another ) "IT Content " in old HD graphics control panel.

Problems?---> have to do that every time I activate / deactivate HDR. Or change the refresh rate... or change the resolution... or every time I get tickled.

This is the Ultimate on Intel Solutions! thans for my pattience.

Best Regards.
