The iPhone 6 is expected to feature a larger screen than the current model, with most reports pointing to a 4.7-inch display. Now a new report from 9to5Mac claims Apple could up its pixel count as well from a resolution of 1136 x 640 pixels to 1704 x 960 pixels to match the new screen size.

The news comes from 9to5Mac’s Mark Gurman, who has an excellent track record when it comes to breaking Apple news. He notes that the new pixel resolution is still in testing by Apple, however. It’s still possible the iPhone 6 could stick with a 1136 x 640-pixel resolution, potentially making it easier for developers to port their apps to the new smartphone. However, increasing the pixel count would mean a sharper display for both the 4.7-inch iPhone 6 and the 5.5-inch Apple phablet rumored to launch in late 2014.

A resolution of 1704 x 960 pixels would bring a 4.7-inch iPhone’s PPI to 416 while the 5.5-inch model would come in at 356 PPI, both besting the 300 pixel per inch Retina standard established by Steve Jobs. It would also mean a significantly sharper display that could help Apple compete with the coming wave of 2K Android smartphones.

In a follow-up report, MacRumors explains how third-party developers will be able to scale their apps for the new iPhone’s resolution. Apple is unlikely to confirm the iPhone 6 screen size or resolution any time soon, but if the rumors are true we’ll probably see Cupertino encourage developers to lay the groundwork for a smooth transition during WWDC 20214 early next month.
