12x 24-inch, let's say on Ergotron mounts, is a nice setup from about the time fractions were eliminated from US equities markets. Assuming one is making a living from trading (work with me on this), otherwise this suggestion might be a bit profligate, consider replacing that panopticon with 3x Apple Pro Display XDR 32-inch 6k -- you'll double your display capacity, improve your ppi, and eliminate 3 of the 5 vertical seams and the 1 horizontal seam.
