According to , Apple is potentially working on a third generation , 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. It’s also plausible that this isn’t a third-generation monitor at all. Let’s discuss.

Last month, Bloomberg’s Mark Gurman reported that Apple begun development on a new external display, codenamed J427, for release in 2026. This would be a successor, rather than a new Pro Display.

However, Apple is also working on an additional monitor, codenamed J527, per Bloomberg :

Now, here’s one twist. I’m 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 we’re 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 . This would make a fair bit of sense, given the fact that it’s been over 3 years since the first generation debuted, and there’s 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 Apple’s Pro Display XDR is nearing 6 years old.

All in all, it isn’t necessarily clear what this J527 rumor means. Could it be a third generation ? 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.
