I use a big 4k monitor from Dell. Not sure what specs other than it swivels between landscape and portrait. I actually have two of them. One I keep in each orientation as well as the monitor on my laptop. I really feel constrained now using just my laptop. When working at my main desk, I keep email and office like junk open on the laptop and use the portrait monitor for coding. The ability to see so much context is invaluable particularly when reviewing code from junior dev's that frequently has 1000s of lines per file. The big landscape monitor I use for data visualizations and sometimes 4 additional panes looking at data.
