  • Apple’s iPad Air Shows Higher Color Accuracy than the Retina iPad Mini


    The Retina display on Apple’s recently released 7.9-inch iPad mini shows a smaller range of colors than the high-resolution screen found on the larger iPad Air and other competing tablets according to a recent analysis. In contrast to the unit’s otherwise impressive gains in resolution and performance, Apple seems to have chosen to equip the new iPad mini with a display that features the same narrow color gamut as its non-Retina predecessor as noted by the folks over at Anandtech. The tablet was bested by Apple’s fourth-gen iPad and new iPad Air, as well as Google’s Nexus 7 and Nvidia’s Tegra Note 7 in testing.

    For those of you who didn’t know, measuring color gamut in broad in broader terms means to measure the subset of colors a display can reproduce within a larger, predefined range. The iPads were subjected to tests that measured their ability to reproduce colors within the sRGB color space, an industry standard range of around 1 million colors designed to be used with computers. Differences in color reproduction are quantified with a measurement called Delta-E, which represents the difference between the color the display is asked to reproduce and the color the display actually shows.

    The Retina iPad mini managed an average Delta-E of 6.5 across the gamut, compared to the iPad Air’s 2.4 and the Nexus 7’s 3.3. Delta-E values of approximately 2.0 or lower are considered unnoticeable to the human eye, while professionals who require display color accuracy, such as photographers and video editors, aim for Delta-E values of 4.0 or lower on their workstation displays.

    The folks over at Anandtech speculate that Apple believes consumers for whom color accuracy is a concern will choose the iPad Air over the smaller tablet by default, rendering the new iPad mini’s marginally narrow color gamut, a difference which calls “small but apparent,” a nonissue.

    Have you noticed the difference?

      my retina mini is on the way, so I don't know what it will look like, but this potentially pisses me off.

      Agreed...why wouldn't they aim for the same specs as the air for the Retina mini...

      yeah, except that nowhere on Apple's website do they ever disclose what appears to be a material difference in color accuracy between the Mini and the Air ... so how would anyone know to choose an Air over a Mini based on whether you like to see the actual true colors?? i thought the choice came down to (1) size preference and/or (2) price. if i had known the display on the mini was of inferior quality, maybe I wouldn't have bought it.

      really seems like questionable marketing practices to me. apple is starting to lose me. they haven't lost me, but crap like this is how it starts.

      like i said, though, maybe i won't be able to tell the difference. i hope not. i guess i can always return it to a store and buy up to the Air if i do notice the difference. which sucks, because i like the size of the mini.

      Simple: so that in 6 months they can release the ipad mini retina S with "a revolutionary improved display".

      They either couldn't or didn't do it because design constraints or to keep margin higher.
      You most likely cannot even tell the difference.

      We know that some iPad mini Retina units have image persistence issues and some do not. We know there are different suppliers for the screen.

      According to Anandtech, the one they tested had absolutely no image persistence issues.

      Apple isn't being deceptive. There have always been variances in quality. My mother's 3GS was acquired late last year from Apple as a warranty replacement. It has an Apple-original screen and it's clearly inferior to my original 3GS. It's clearly not an IPS display.

      The exact same difference was obvious between my iPhone 4 and iPod touch 4th generation.

      I've noticed that my early iPhone 5 unit screen looks noticeably different from newer ones I've seen in the Apple store.

      Even if the color gamut issue does affect all screens from all suppliers, it's insignificant to anyone except graphic publishing professionals. Seriously. Those are the *only* consumers who should give two shits about this...and they already know to find out about the color gamut from reviews before they make any tech purchases.

      Whiners.
