OpenCore Sequoia problem with second screen

I installed Sequoia 15.0 with the help of OpenCore Desktop Coffeelake Z390

That's my hardware

Asus Prime Z390-P
Intel Core i5-9600kf
MSI RX580 8GB
64 GB 2400 DDR4 Hynix Ram
2 TB SSD
Fenvi T919
Display: 34" 3440x1440 & 24" 2560x1080

So far, most of the stuff works. The only big problem is the video output works only for 1 screen. I use my big 34" but I don't get any signal to the second screen.

That's my boot args:
-v debug=0x100 keepsyms=1 alcid=1 agdpmod=pikera

That are the Kext:
Lilu.kext
VirtualSMC.kext
WhateverGreen.kext
SMCProcessor.kext
SMCSuperIO.kext
AppleALC.kext
RealtekRTL8111.kext

ACPI:
SSDT-AWAC-DISABLE.aml
SSDT-EC-USBX.aml
SSDT-SBUS-MCHCaml
SSDT-PLUG.aml
SSDT-PMC.aml

The Fenvi T919 WiFi/Bluetooth also doesn't work, but there is apparently no solution for this yet.

Does anybody have a similar problem or a tip how I can get the second display to work?
