How to Force HiDPI on a Cinema Display
How do you simulate a retina display on a 27" Cinema Display? The main tool used to accomplish this SwitchResX. This will allow for custom resolutions and enabling HiDPI for those resolutions. I'm using a MacBook Pro (Retina, 15-inch, Mid 2014) model with the Intel Iris Pro 1536 MB for reference.
