Apple finally embiggened the iPhone's screen. The taller screen, now 4-inches, retains the incredible sharpness of its predecessor. The new 1,136-x-640 resolution keeps the Retina moniker and has a pixel-per-inch (ppi) ratio of 326. The IPS LCD on the device remains a leader in color reproduction and viewing angles.
Now here's a surprise. The 8X's screen is better. The slightly larger 4.3-inch screen is also an IPS LCD panel. The resolution is 1,280 x 720, giving the 8X a ppi of 342. The sharpness and color reproduction match or exceed that of the iPhone 5. Really.
