About this app

Read full description

Not all displays for Mac are well suited to display the user interface in a non-scaled resolution. A pixel density of about 110 pixels per inch (PPI) for non-Retina, and about 220 PPI for Retina is comfortable for most people. Use Retinal to work out the pixel density of any display.
