iOS 9 Code Suggests 12.93-Inch 'iPad Pro' Could Have 2732×2048 Display
Taiwanese iOS developer Hiraku Wang has shared further iOS 9 beta code (via Steven Troughton-Smith) that suggests the 12.9-inch "iPad Pro" could have a 2,732×2,048 pixels display at 264 PPI based on Apple's @2x high-resolution modifier. The findings corroborate a DisplaySearch report from last January, in which the research firm said that Apple had a tablet display with a resolution of 2,732×2,048 pixels and 265 PPI under development.
Apple's existing lineup of iPads with Retina displays, ranging from the third-generation iPad to iPad Air 2, each have 9.7-inch screens at 264 PPI, so it would make sense that the larger 12.9-inch "iPad Pro" would have a scaled up resolution with the same pixel density. Specifically, a 2,732×2,048 display with 264 PPI points towards an approximately 12.93" diagonal screen size. As a @2x display, this would represent 1,366x1,024 points as shown in the onscreen dimensions for the keyboard.
