An 8K iMac is far from implausible, as Apple already has a 27-inch 5K retina iMac with 5,120 x 2,880 pixels. On top of that, VESA's new DisplayPort 1.4a standard now allows 7,680 x 4,320 8K displays. (That's an eye-popping 33-megapixels if you're keeping score at home.) However, we're taking all the information with a certain amount of salt, since it could just be a simple mistake or misunderstanding. That said, LG is the manufacturer of record for Apple's 5K iMac and has since taken down the post. We've reached out to LG and Apple for comment, but at this point we're not holding our breath.
