4 desktops on my screen.

So..

I've got a Overlord Tempest X270OC from my nephew, but i have a small problem..

It shows the image from the computer 4 times, both in Windows and while booting.
Using DVI cable and have a another monitor 24" fullHD monitor via HDMI (working perfectly at the same time).

Any ideas?

Running windows 7 pro 64bit, GTX 1050 Ti OC, newest drivers, using NVIDIA Pixel Clock Patcher 1.4.2 and Custom Resolution Utility (CRU) 1.3.1
