The seventh beta of macOS Monterey, released earlier this week, includes a pair of new entries in a list of display resolutions for the System Information app, potentially revealing the resolutions of the upcoming “M1X” 14-inch and 16-inch MacBook Pro models.
As discovered by MacRumors contributor Steve Moser, the two new display resolutions are listed as “3456 x 2234 Retina” and “3024 x 1964 Retina” and do not correspond to resolutions of the built-in displays on any current or previous Apple products. Based on the resolutions themselves and their relationships to each other, it seems likely that these new resolutions are for the upcoming MacBook Pro.
The current 16-inch MacBook Pro has a native display resolution of 3072 x 1920, while the current 13-inch MacBook Pro’s native resolution is 2560 x 1600, giving both machines a pixel density of 226–227 pixels per inch.
