For what it's worth: 1) I don't recall ever seeing a Mac laptop that offered more/different video support when in clamshell mode than when it was open. (Doesn't mean it has never/won't ever happen, but it would be a little unusual.)
2) The 24" 4K Dell P2415Q gets pretty good reviews (as does the 27" Dell P2715Q, which doesn't cost much more). If you're going to experiment with that, though, I'd get it from someplace with a good return policy--we're all guessing a little about whether it'll work as you hope. 3) Note that the new Retina MacBook can't drive Apple's 27" Thunderbolt display (USB C≠Thunderbolt). Hope that's useful somehow. Ian > On Apr 22, 2015, at 5:54 PM, Ryan Lovett <[email protected]> wrote: > > Thanks Tim! That is helpful.
