I'm interested in replacing my 27" 2560x1440 display with something of a higher resolution and larger, but I haven't found anything I like. You can get 30" 2560x1600 displays, but while I like the taller aspect ratio, there isn't that much more usable space and the DPI is too low. It's old tech, I had one 10+ years ago. There are also the new 34" widescreens, optionally curved, which at 3440x1440 are just wider versions of my 27". That could be neat, but I'd like to have more height to work with.

Another option is the 27" 5120x2880 LG display that Apple sells. That's like a "retina" version of my screen. I could run it at a higher effective resolution than 2560x1440 when I need more space, but this feels like a tradeoff -- my eyes aren't so great. I don't like tiny text. I'd also have to buy a newer Macbook to drive it... meh.

I'd like to get something that runs at the DPI my 27" display provides, but larger on all sides. I stare at a monitor for most of my waking hours so price isn't much of a concern, but as far as I can tell, nobody makes something like this.

I thought about two 27" displays rotated 90˚, but subpixel rendering goes away when the panel rotates and it looks horrible. I also wouldn't like a big seam down the center of my monitor.

Any tips?
