I got them recently as the side monitors for a 16:9 43'' 4k in the middle. The height matches almost perfectly. I love this layout so far, so much desktop space and such high resolution! And it's nice to have a big 16:9 screen in the middle for videos. Finally a worthy replacement for my three 10-year-old 30'' 16:10 Dells.

For people who work in Windows: you will want to use https://github.com/mgth/LittleBigMouse and you'll need to modify the registry to work around this issue https://github.com/mgth/LittleBigMouse/issues/80 if you don't want your mouse cursor to jump vertically during screen transitions.
