In OSX i had trouble connecting my screen i had to lower resolution before it worked.
But in boothcamp through windows i knows there is a second monitor but it will not give me the option to lower resolution to fix the issue.
Can anyone advice me how to get my screen working properly in boothcamp?

I use two Dell U2715H monitors using USBc-to-DP on a 2018 13-in 2018rMBP at 2560x1440. Your ProVega 64 GPU will support 4K. It may be worth the effort to try a USBc-to-DP cable.

Simultaneously supports full native resolution on the built-in display at millions of colors and:
Thunderbolt 3 digital video output
Do you have a USBc-to-DP cable?
I also tried restarting windows(bootcamp) in save mode with a low resolution setting duplicating the screen then is possible but as soon as i try to extend it disappears, also in normale settings lowering the resolution and then duplicating doesn’t work. (This way i was able to reach the settings for the monitor but setting it to a lower resolution like on osx doesn’t seem to solve it)

What is the physical connection between the Adapter and the Monitor?
Misclicked the first time so can no longer mark this as the correct answer but put that on the first reply.
but thank you very much this is indeed the correct solution it now also takes the higher resolution in OSX.
thank you for your time!

Excellent! Glad to see it working properly.
Be aware that there is a newer model of About the Apple USB-C Digital AV Multiport Adapter - Apple Support. I will paste it here for reference as well.
Model A2119 is the newest model of this adapter. It supports HDMI 2.0 at these resolutions and refresh rates when used with macOS Mojave 10.14.6 or later or iOS 12.4 or later. It also supports HDR video in HDR10 and Dolby Vision formats when connected to a compatible playback device and display, TV, or projector.
Model A1621 supports HDMI 1.4b at these resolutions and refresh rates when used with macOS Sierra 10.12 or later or iOS 12 or later:
Hdmi cable (which works with the highest resolution for other laptops)
What is the screen resolution for the external monitor in Windows set to?
It try’s to be in it’s recommended resolution like in osx 3440x1440 (Lowering it to 2560x1080 in osx fixes it) but cant really set it in boothcamp
What is the brand/model of your display?
Samsung/ LS34E790CNS/EN
No, but i can buy one if you think it will solve the issue.
Orderd the Moshi usb-c cable which is also on the apple website. Once it arrives i will let you know if it works. Thx for the help.
(might take a view days not being sold in the netherlands)
The Moshi cable on Apple's web site is expensive. In US, it is USD49.95.
