My desk at work. So far, it's the most optimal setup. The main #workstation is a triple monitor setup, with the middle and right monitors are 4K. The left monitor is standard hi-def. My laptop can function as a fourth display. Portrait mode in 4K is simply incredible for #terminal and #ssh work. All mounted on a standing desk.
I use the dual monitor system on the left as a secondary on-prem machine and remote jump box. The monitors are just standard hi-def, but still plenty of real estate.
Portrait mode is underrated.
