Display for rMBP

[gadgetgirl85]

Thinking about getting a display for my rMBP. Would like retina/4k. Any suggestions?

only retina 4K is 24", probably one of the dells

Hmm..so nothing in 27"? Anything nice in 27" that isn't? Say if Apple were to bring out a retina iMac at some point what would be on par with the display?
