set up 2 monitors. One above Mac and one vertical one to the left of the monitor above

Hey all

I have a Macbook Pro. I have. 2nd monitor which works great. I've purchased a 3rd monitor that sits to the left of the monitor above my mac.

I want to use 3 screens.

My Mac

My monitor directly above my mac screen

A third monitor that is VERTICAL, to the left of my monitor above my mac.

I can get the left monitor to have an orientation at 90degress, which works fine, but I can cannot move my curser UP to the monitor above my main mac screen. All three only move from side to side.

Ideally, I'd like to be able to have my second monitor directly above my mac as always, and they move my cursor to the left from my secondary monitor, onto the vertical monitor to the left of both my Mac and my secondary monitor.

Please let me know if this is possible or if I have to re-think my configuration
