Limited External Display Support

That’s because only the left/rear USB-C port includes DisplayPort support. That means you’ll either need to disconnect your external display or invest in a DisplayPort hub if you also need to use a high-speed USB device at the same time.

Specifically, the MacBook Neo supports DisplayPort 1.4, and it surprisingly does allow the built-in display to be used at the same time. That’s something the iPhone can’t do, and it’s enough to make us wonder if rumors about expanded display support on the iPhone last year actually stemmed from leaks about making the A18 Pro chip do this.

You’re still limited to connecting a 4K display at 60 Hz, but we really shouldn’t expect more from a $599 MacBook — and there’s a good chance you won’t be able to use it with Apple’s new Studio Display.
