nVidia Surround 1440p and HDMI

Hi, I am hoping someone here can help me with this problem i'm having.

Hardware:
I have 3 Gigabyte g32qc monitors. These are 31.5inch 1440p 165Hz monitors.
They are connected to my videocard (Asus Tuf 3070).
2 monitors on Displayport, 1 on HDMI

Problem:
All of my monitors are set to 1440p 120hertz, they all show up and work well with that resolution and refreshrate in windows.



When I try to enable nVidia Surround however.. my max resolution is 1080p rather then 1440p. It should be 7680x1440 but all im able to get is 5760x1080






Things i tried:
- When I run all 3 monitors on displayport I am able to get nVidia Surround to work in 1440p, 120 or even 165Hertz. But I need 1 displayport for my VR headset.



- Trying just 2 monitors on HDMI (videocard has only 2 HDMI ports). nVidia Surround this time wants to put them in 4k.



- Gsync turned off
- I also tried a HDMI > Displayport adapter (supports 4k60hz), doesnt change anything.
- I tried CRU, but im not experienced enough to know what I should be changing here, I messed about a bit, but thats not working.





Anyway I hope someone here could help me
