Recommendation: 24-28" monitor that rotates (vertical/horizontal) and is DEFINITELY compatible with the iMac Retina 5K Late 2014?

Question

Can anyone recommend a good 24-28" monitor that rotates (vertical/horizontal) and is DEFINITELY compatible with the iMac Retina 5K Late 2014?  Will be running three screens (two monitors on either side of the iMac).  Plug and play would be nice.

Answer 1

Any LCD (LED backlit) display would be compatible with any apple-branded machine, pending it supports DisplayPort (there are HDMI to DisplayPort/Mini/Micro adapters for a reason). Doesn't have to be apple-branded.
