The Dell UP2414Q can be physically rotated into portrait orientation on some Macs, and a 2160 X 3840 resolution chosen, as shown below. (the late 2013 MacBook Pro Retina Displays control panel offers no 90° rotation option).

While this worked fine on the 2013 Mac Pro, there were two dissatisfiers:
- On the 2013 Mac Pro, the mouse cursor movement is not satisfactory. This is probably due to the 30 Hz setting, but in landscape orientation the mouse movement feels better. It probably has something to do with many more lines on portrait orientation.
- The default scaling in tends to cut off images in the web browser, so a scaled resolution has to be chosen, or the web page viewing size reduce (easy enough to do, but...).
