Triple Monitor Setup not working

[Wcrumb]

I recently installed MacOS Sierra, and everything is working mostly fine. However, only my primary (middle) monitor is working. The other two are black. Also, my monitors are in portrait orientation, but I can't make them portrait. So, I have to turn my head to look at them/the middle one. I have installed the Nvidia Web Driver, so I don't think the problem is with the gpu drivers. Any help would be greatly appreciated!

I have to turn off my 4k middle screen (display port) until the boot up is done then its cool.
Other 2 screens are 1080p using dvi and hdmi.
If I dont the thing wont boot. maybe try booting with different screen combo's turned on.
Not upluged from the computer, just turned off with power button.
worth a shot??
