LG sells a DualUp monitor that is 2560x2880, same size as two 2560x1440 displays stacked on top of each other: https://www.lg.com/us/monitors/lg-28mq780-b-dualup-monitor

Yep, though what I would want is the width and height swapped. You can rotate the monitor, but then the subpixel layout isn’t good for text.
