Late last year Apple unveiled a new iMac thatincluded a 'Retina 5K Display,' measuring 27-inches and featuring a 5120x2880 panel. A display with that amount of pixels blew past the competition and established the iMac as one of the go-to desktops for photo and video editing after a period of few upgrades.
Now, it seems like Apple could be improving upon the theme of the 5K display with a new 8K display, according to a press release posted by LG Displays entitled "Next-generation of High-resolution 8K" which references an "iMac 8K" (LG currently manufactures the iMac 5K's display). An 8K display has 7680x4320 pixels and LG showed off some 8K displays at CES 2015, stating that they include 16 times the number of pixels of a full-HD display.
The press release explicitly names Apple as releasing an 8K display "later this year" (emphasis ours):
It has become clear that Japan is planning to launch an 8K SHV test broadcast and then promptly restructure the UHD service. Apple has also announced that they will release the ‘iMac 8K’ with a super-high resolution display later this year. Korea is also preparing to offer an 8K service demonstration at the 2018 Pyeongchang Winter Olympics. LG Display displayed a new beacon of the 8K era by revealing their 98-inch 8K Color Prime Ultra HDTV at CES 2015.
As anyone who follows Apple knows, they have not "announced...'the iMac 8K'" meaning that LG has either made a mistake or has accidentally let slip about an unannounced iMac. 8K displays are pegged as coming to market sometime in 2016 and so it would stand to reason that Apple has been testing out an ultra-high resolution display, potentially for their standalone display range which hasn't been updated since 2011.
Neowin has reached out to LG to ask about this particular post.
