DisplayMate compared the screens of several smaller tablets, and judged that the recently-released iPad mini 2 has a noticeably poorer display than the Google Nexus 7 II and 7-inch Amazon Kindle Fire HDX.
The majority of the criticism came in the area of Color Gamut — the range of colors that a display can produce. Amazon‘s and Google‘s tablets scored well in this area, but Apple‘s did not. DisplayMate said, “As a result, the iPad mini with Retina Display comes in with a distant 3rd place finish behind the innovative displays on the Kindle Fire HDX 7 and new Nexus 7.”
This isn’t to say it’s inferior to its rivals in every way. All three models have almost the same pixel density — almost exactly 326 ppi — so they produce very sharp images. And each received good marks for brightness, viewing angles, and screen reflectance.
That said, the second-generation iPad mini starts at $400, while the Google Nexus 7 (2013) and 7-inch Amazon Kindle Fire HDX start at $230 each.
