You can temporarily destroy an OCD person's productivity by giving them dual monitors.
Getting them physically aligned and color matched is not for the faint of heart.

This is why you go ultrawide instead. 2 monitors worth of width, 1 bezel
As long as your OS has decent window layout tools.
That also takes away the 1 wide and 1 tall option which is awesome for certain workloads.
Even if you don't have a good set of layout tools, a lot of 32:9 ultrawides are capable of being run as two separate 16:9 displays. Works great for Windows, but since I use Linux and have plenty of great tools to manage my windows, I just use the single 32:9
I'm running dual 4k. Took a look at the ultrawides and that res is unobtainium. Probably because the bandwidth for that is so high it takes 2 cables.
