Best for: Replacing a two-monitor desk with one curved panel and one cable
21:9 and 32:9 panels that replace two screens with one, so there is no bezel down the middle and one cable carries everything. The catch is vertical space — a 34-inch ultrawide is shorter than a 27-inch 16:9 — and software that assumes a 16:9 window.
