I have two Dell P2715Qs and love them. The killer feature for me was one mDP and one regular DP input so I can just change inputs to switch from work (MBP) to play (desktop). Most other similar displays only have one DP input.
I'm happy to hear this. This is the display I've actually been considering if I don't stay with Acer. The coating on the screen and general sense of quality is attractive. Any drawbacks you've seen?
The only drawback I've encountered is one that seems quite common to DP displays: when I turn a monitor off or switch inputs, both my OSX and Win8 machine behave as if I just physically disconnected and reconnected the cable. Haven't found a way around this yet, but it's a pretty minor inconvenience.
That's what that is! Thanks for mentioning this. With Linux also, when I turn my monitor off, it does seem to treat it as though the display was removed. That's interesting. Glad to know it's not an OS thing.
