The screen experts at DisplayMate.com have performed a iPad mini vs Nexus 7 vs Kindle Fire HD  display testing.  

Calling the test in-depth is something of an understatement, the DisplayMate.com comparison covers lab measurements of: Screen Reflections,  Brightness and Contrast,  Colors and Intensities,  Viewing Angles,  Display Backlight Power Consumption,  Running Time on Battery. You can also skip the Highlights and go directly to the Conclusions.

The conclusions aren’t always flattering for the iPad mini. DisplayMate.com notes that “The $199 Amazon Kindle Fire HD and Google Nexus 7 both have considerably sharper displays with 216 Pixels Per Inch, and they both delivered considerably sharper text.”

It notes that “one advantage of the iPad’s more square 4:3 screen shape is that it lends itself better for use in both Landscape and Portrait viewing modes. Another is that a 4:3 screen is often better suited for reading because it has the same Aspect Ratio as content on 8.5x11 inch documents”

DisplayMate.com also offers some advice to Apple on how it can improve the iPad mini display. As well as increasing the screen resolution, Apple could improve the sharpness of the display, and  

They also note that “While screen Resolution gets lots of attention from both consumers and marketers – it’s really only critical for providing visually sharp text”. When it comes to playing games, watching video, and general tasks the iPad mini is as good as its larger brethren, but considerably lighter and more portable.

In our iPad mini review we called the iPad mini the best iPad option (and best tablet) because it combines the right size, weight, and feature set with a good display. But it’s clear that Apple’s decision to arm the iPad mini with a non-Retina display is going to remain contentious for the time being.
