My GIS rig is different than any of those.
Vertical monitor on the left, ultrawide lifted a bit high on the right, and open laptop screen beneath the ultrawide.
Verticals for email, teams, etc. Big ultrawide is mostly for main GIS window and spreadsheets, and laptop screen is kinda general purpose.
I actually have a 4th monitor technically, but it’s a big TV on the wall of my office that’s usually turned off, but that I can use for presentations or screen-sharing when I’m meeting with people in my office.











Yes, but blue (Mercator) preserves direction and shape, which were all that really mattered for navigation by sea, so Mercator was a fantastic projection for centuries.
And we still use it today for smaller scale areas, since it does a remarkably good job at preserving all 4 features (shape, area, distance, and direction) close to the map origin line. Universal Transverse Mercator is a system that has 60 zones of Mercator turned sideways.
The reason it’s Transverse is because, unlike lattitude depending on a defined equator, longitude has an arbitrary meridian, so by turning the map sideways we can move the distortion point, and any map area that doesn’t stray too far East or West will be very accurate.
Think of trying to map something like Chile or Florida, where the area of interest is pretty far North to South, but not East to West.
