4K 144hz monitor detected as 2 seperate monitors(dual dp 1.4)

[X39]

I’m using an Acer/ConceptD CP3271KP monitor that is 4k 144 hz if you use 2 dp 1.4 cables. It is being detected as 2 separate monitors both at 3840x2160. Any help is greatly appreciated.

What is your GPU model and what if you use just one cable?
