Last week we noted that the low supply of Apple's new iPad mini was being blamed on burn-in problems with Sharp's IGZO display.
Arment had previously created a test to identify the problem in 15-inch MacBook Pros. Navigating to this page will show a large black-and-white checkerboard pattern for a few minutes then switch to solid gray.
"If the LCD panel has an image retention issue, a faint impression of the checkerboard will still be visible on the solid gray image, usually fading over the next few minutes."
After getting a new Retina Display iPad Mini, Arment tested his device and it unfortunately exhibited the problem, as can be seen in the photos below.
While not something that most would notice in actual use, it is affecting some users. Notably, Arment had some friends run the test on their devices and none of their devices demonstrated image retention.
