I'm looking to replace the ASUS HD monitor for my Mac Pro. Any suggestions from forum members? What are you folks using? I'm looking for a (roughly) 27-inch, IPS, 4K UHD (3840 x 2160), mini-Displayport display. There was a discussion thread about monitors here at NRF a little more than a year ago, but the offerings have changed a lot since then. I've looked into about a dozen monitors thus far, and none of them is totally satisfactory, so I know I will have to make some compromises. Two possibilities I'm now considering are the LG 27UD68-P and the HP Z27s, which are in the under $500 price category, but I'm a long, long way from pulling the trigger on either one. I'm willing to spend as much as $1200 or so for a decent monitor that can be calibrated, but it would have to be "future-proof" at that price.
