All the displays feel robust and can be tilted vertically for comfort, but to rotate horizontally, you have to turn them on the spot. The NEC deserves commendation, as you can adjust its height as well.
Some displays (Hanns G, LG) keep the controls out of the way for aesthetic purposes, while others (NEC, BenQ, Asus) have them on view.
The Samsung's side-mounted buttons are labelled with an on-screen graphic when in use, giving the best of both worlds. The Hanns G looks best, with a matt black finish and no obtrusive distractions.
The LG's shiny black finish with clear plastic details gives it an unusual look. It features an interesting means of switching it on too; a droplet of clear plastic recognises your touch. However, it's easy to snag when you operate the buttons on the side and can accidentally turn off the display.
Incidentally, each monitor in the test features a black design. We let the manufacturers choose what to send us and it seems black is in!
