I'm looking for a monitor that can be set up in portrait layout. (Yes, I know how to set it up in OSX). I'm looking for a monitor that can be physically set up that way. All of the monitors I'm seeing can only be set up in landscape. I'm guessing maybe there is some sort of swiveling stand to switch from landscape to portrait, or maybe two different stands. Maybe something 22-23" or so? I have mini display port on my MBA, so probably a DVI would be ideal. Does anyone have experience with this setup? Thanks!
