On the 2013 Mac Pro

Get the Dell UP2414Q at B&H Photo for about $949.

The Dell UP2414Q was tested on the 2013 Mac Pro by connecting it as a 3rd display, in addition to a NEC PA302W and NEC PA301W (dual 2560 X 1600 30-inch displays). That’s a lot of screen real estate, but the 2013 Mac Pro handled it with aplomb.

Handy trick if a 4K display is to be used for its resolution with no concern for text size, configure it at native 3840 X 2160 resolution; it reduces the size of any web browser or similar stuff around images (no need for pixel doubling / scaling). See further below for details.

As shown below, dual 30-inch 2560 X 1600 displays are accompanied by the 3840 X 2160 Dell UP2414Q at right. The NEC PA302W has the menu bar at center. This configuration worked with no issue whatsoever on the 2013 Mac Pro.
