Razer X Chroma not working with Mini Intel Nuc

Hello ! Last week I recieved my Razer X Chroma with a Gygabyte Geforce 3060 Eagle 12Go. My purpose is to boost the graphic power of my Intel NUC NUC8BEB. However after setting up the display following the instructions I still have a problem making it work.

• I have let Windows recognize the display and installed the drivers.
• I have Installed the drivers of the Geforce 3060.
• I have updated Windows
• I have updated all the drivers of the Intel NUC

I have succeeded to make it work randomly. I have tested the power on The Witcher 3 and it worked extremely well. But after restarting the Computer every thing went wrong. There is actually no way to make it work. The screen doesn't even show up whenever I plug the HDMI on the Razer X Chroma. I have tried plugging it after the computer had started, before, etc... I am now wondering if my Geforce 3060 is compatible with the Razer X Chroma, because on this graphic card there is only one PCIe 4+2 plug instead of two. Even if as I said earlier The WItcher has worked. Well, Can you help me ?
