An unknown but growing number of iMac users are reporting display failures on their M1 iMacs, typically around two years after purchase.
Apple has had screen issues of various types before, and it’s perhaps not surprising given the complexity of displays. But this new one has the extra sting that it appears to be mostly happening after the iMac is out of warranty.
The first reports, as spotted by Tom’s Hardware, came in October 2023.
”Persistent horizontal lines appear on the screen [of a 24-inch iMac], which significantly hampers the usability and visual appeal of the device,” wrote user latVm on Apple’s discussion forum. ”This problem arises without any physical damage, and despite the stationary nature of the device.”
