I have two of these monitors attached to my GeForce RTZ 3060Ti
I have one HDMI cable going from the card to a Greathek 4 port Dual Display KVM. I then have a DP cable going to an HDMI converter to the KVM

I need the KVM because I have multiple systems. I work from home twice a week and need to connect my work system to the monitors, keyboard, and mouse. I also do work on friends systems that I plug into the KVM.

Lower your refresh rate in the nvidia control panal, apply it, then go back and switch it from 8 bit to 10 bit and apply it.
I just moved to HDR and discovered there's a physical data transfer rate limit to the DP 1.2 cable. If I raise the refresh rate above 120 @ 2560 x 1440 it automatically drops to 8 bit with dithering on both my RTX 3060Ti and RTX 4070, both using the same monitor.
I'm using 2k native, seems your using 4k native? I don't think you can use the same refresh rate. You may need to lower it to 60 for 4k. I do know you need it low enough to be able to use 10 bit color gamut.
Tinker with it and let us know what settings you end up with.

Once you do you can confirm it by going into the advanced graphics setting in the windows display settings. I'm still on 10 for a few more weeks so I don't know exactly what that looks like on 11.
I'm also using G-Sync so I use the Nvidia control panel to limit my FPS to just below my refresh rate then disable V-Sync in all my games.
