Fine adjustment of second screen?

[Andrew88]

Hi guys. I need some help.

Just bought a second screen to stand vertically next my primary, but i'm having a hard time getting Win 10 or nVidia to adjust the height properly so that the mouse cursor is at the same height when I move from one screen to another :(

Both programs want to "snap" the screen into place when i try to drag it to the right spot.

Any advice would be much appreciated :)
