Apple tells Ars Technica that he believes that the “jelly scroll” effect that some users have noticed on the new iPad Mini is normal LCD behavior that the company will not need to correct. The effect, also known as tilt, can make one half of the screen appear slightly behind the other as you scroll, and it’s most evident when using iPad. Mini in portrait mode. Edge Editor-in-chief Dieter Bohn noted the problem in a tweet and in his review of the device published this morning. Despite our requests before and after the publication of the review, the company did not respond or comment.
Ars explains that the problem occurs because the iPad starts to draw lines on one side of the screen and it takes time to move from side to side. A little time, yes, but it can be noticeable depending on the device.
You can see what it looks like below:

In normal use you barely see it, but every now and then it becomes noticeable. In landscape it goes away entirely pic.twitter.com/iq9LGJzsDI

If you want to see how LCD screens refresh in shocking detail, The Slow Mo Guys on YouTube made a video showing how it works with TVs and iPhones.
Apple is correct that this effect is common in LCD screens. It is very possible that the screen you are reading this on right now will have the same effect if you load a webpage that tests it – my laptop shows this quite strongly. The reason it stands out on the iPad Mini, however, is that it’s frequently used in alignments where the problem is most noticeable – it’s unlikely to be a problem on a landscape display where you scroll vertically. .
This effect also occurs with many video cameras, for much of the same reasons: if you pan fast enough, straight items like posts and trees will tilt to one side, as data is read from the camera. top of the camera sensor down.
While the effect is common (and subtle on the iPad Mini, we don’t think it’s a big deal given the quality of the screen and the inclusion of USB-C), it looks distinctly worse on this particular model than other recent iPads. It also seems unusual that Apple doesn’t care while still managing to avoid the jelly scroll on high-end iPad models and even my previous generation iPad Mini (which sold for much less than the new model).
