Feld & Volk put the new display under a microscope to make that determination.
That resolution has been long been rumored for the larger screen of the next-generation iPhone because it would make the transition process simpler for app developers. The current iPhone 5s has a resolution of 1,136 by 640 pixels.
Even so, MacRumors did spot a major discrepancy with the photo and the information provided:
The photograph posted by Feld & Volk does not, however, necessarily appear to agree with that claim, as it seems to show roughly 13 pixels per mm in the horizontal and vertical directions, while a 4.7-inch display at 1704 x 960 should be closer to 16 pixels per mm. The current iPhone 5s display is roughly 10.5 pixels per mm.
Interestingly, 9to5Mac earlier today reported that it found references to a resolution of 1,472 by 828 pixels in a beta version of XCode 6 for developers.
While the conflicting information is interesting, the most logical explanation is that the 5.5-inch version will have a 1,704 by 960 pixels resolution and the smaller handset will offer a 1,472 by 828 pixels screen.
Apple is widely expected to introduce both versions of the iPhone 6 at a special media event on Tuesday, Sept. 9.
