hello. thank you for the reply. good thing i have VR cable and it works perfectly, i just wanted to simplified my setup since Belkin cable it too long and bulky. So things ended up i trashed some money upgrading the motherboard
....update: i connected XDR display through OWC TB4 hub this time, somehow it was connected in 6k 10bit HDR. i don't understand what have changed inside but pretty happy with the result. note that this worked without Belkin cable, just GPU(4090fe -> MB(z690i unify) miniDP input -> OWC hub(TB4) ->XDR display
You have two other options:ㅎ

How many DP cables you use in this case? It's really interesting, that it allows you full 6K through TB port.
It returned to 5k tesolution after the reboot(and windows update). 🥲 i’m tryinf several tests.
For the record before the windows update it maintained 6k HDR within few reboots.

└────────────┘I'm waiting for arrival of CABLECONN usb-c hub. It doesn't require any fancy cables and USB goes just through USB-C. According to forum member experience, that's the best value for money (48 USD for my country, but you can try to find the same looking, but cheaper from other brands), btw it's not a TB hub.
Yep, this one. I tried to find it on international amazon, but it was not there.
Thanks for this.
I've got it today and tried with my M1 MBP and Intel PC. Both work perfectly with this KVM, XDR works at full 6K@60 8-12 bit + HDR, brightness is controllable in both Windows and Mac.
KVM is used just for easy switch between two computers without re-plugging everything. The flaw here could be data transmission speed - only USB 2.0 480 Mbps on PC and not quite clear 20 Gbps (according to the system report, although the used cable supports only 10) on Mac.
Reading this thread, looks like the Ryzen 7000 series does support DSC over Displayport 1.4/2.0, and that motherboard claims to support Displayport 1.4 over the USB4 connections. So ... in theory it'd be able to run the Pro Display XDR at 6k, but I don't know if anyone has actually used a Ryzen CPU with integrated graphics to drive this display in the past.
It could support it by itself, but at the same time there's TB4 controller that can disallow DSC through TB. I have Z590 Vision D board with the same TB controller and I couldn't get 6K. Although I used discrete GPU (which definitely supports DSC) instead of iGPU (which doesn't).
