According to Bloombergs Mark Gurman, Apple is potentially working on a third generation Studio Display, codenamed J527. This would be a version ahead of the already rumored second generation Studio Display, which is codenamed J427 but feature advantages of the third generation display are unknown. Its also plausible that this isnt a third-generation monitor at all. Lets discuss.Last month, Bloombergs Mark Gurman reported that Apple begun development on a new external display, codenamed J427, for release in 2026. This would be a Studio Display successor, rather than a new Pro Display.However, Apple is also working on an additional monitor, codenamed J527, per Bloomberg:Now, heres one twist.Im told Apple is working on a second new monitor code-named J527. At this point, it seems unlikely that the device would be a subsequent generation,given the amount of time between updates and that were still a bit away from the J427.Gurman suggests that J427 and J527 might end up not being distinct products, and instead Apple is just prototyping with multiple options for a second generation Studio Display. This would make a fair bit of sense, given the fact that its been over 3 years since the first generation Studio Display debuted, and theres still over a year before the rumored second generation model will launch.Additionally, Gurman speculates that J527 could end up being a second model with a different screen size or set of specifications, and mentions the fact that Apples Pro Display XDR is nearing 6 years old.All in all, it isnt necessarily clear what this J527 rumor means. Could it be a third generation Studio Display? Studio Display Pro? Pro Display XDR 2? Who knows. The 27 number in the codename would heavily suggest that this will have a 27 display size, at least.My favorite Apple accessories on Amazon:Follow Michael:X/Twitter,Bluesky,InstagramAdd 9to5Mac to your Google News feed.
