Interesting - so Kuo and Young, two highly reputable and accurate analysts, are in complete and direct opposition to one another. It’ll be interesting to see who’s right. Kuo’s claims make more sense, but Young is almost never wrong and seems very sure that he’s confirmed there’s a 27” 5K mini-LED panel in production for Apple. Hmmmmmm…
They likely both have sources who are reporting that a 27" 5K MiniLED ProMotion panel exists and they are both presuming it will go into an Apple-branded product, but they don't know what product so they've been guessing between an iMac Pro and a standalone display as those were the two most obvious options.
iMac Pro was the front-runner until Apple unveiled the Mac Studio, which arguably sits right where an iMac Pro would have gone into the lineup. So now they're hedging their bets and saying it might still be for an iMac Pro, but it also might be for a standalone display. And the latter option is likely being boosted in some part as other sources (dylandkt) said LG is/was working on a prototype display that was 27" 5K with MiniLED and ProMotion and LG is the supplier of 5K panels to Apple.
