4k screen flickering

[emulatoronlinexyz]

I have a 4k monitor and display is flickering nonstop.
When I try to connect 2 ports into the same monitor, only one of the disolay is working other one stays black. But in settings it shows up 2 monitors connected.
In both situation working monitor is flickering.

I tired to connect the monitor directly to the hdmi out and also via thinkpad docking station.
I'm on Ventura latest version
Bios 0061
Cfg lock is done, disabled
Bios settings are the same as described

Please use lastest EFI nuc10 oc 0.9.9

reset nvram

set bios like this

IGD Primary Video Port -> Thunderbolt or HDMI (Depends on your default monitor)
IGD Secondary Video Port -> None

it's all good with 2 4k60hz monitor

after your suggestion the screen is not flickering so often (maybe 50% fewer) but it keeps still flickering.
when i change the resolution to 1080p it`s very rare flickering. :S
the cables are ok. i use them on my other hackintosh system with 4k resolution with no issues.

Edit: I tired to install/update to sonoma to check if there's no display issue. It doesn't update or clean install sonoma.
With clean install, I can reach recovery make a fresh install after reboot it says xx minutes left and it's also done then reboot again and then I get only boot loop.
The progress bar jumps from 5% to 25-30% suddenly and reboot itself.
Is there any special change to install sonoma?

System specs:
NUC10i7FNH
16gb 2400mhz
250 GB evo 970 plus m2(Windows installed)
500 GB evo 870 Sata ssd (Macos)

I use lenovo usb c docking station
I tired also update/Installation without dockingstation. The same results

If you look online, many of the bluetooth-related kexts must be disabled to successfully upgrade or isntall sonoma. Once you're in and all is updated to latest sonoma, re-enable the bluetooth kexts.

Finally i installed 14.4.1 succesfully. I needed to format macos disk completly from windows (erasing on macos recovery didnt work).
However flickering issue is still there.
i tried the system on 2 1080p monitors with a hp thunderbold dockinstation. There were no problems at all.. i couldnt figure out whats the exact problem with 4k monitor (at least with my 4k monitor)
