CRN US reported that "the most significant addition in Surface 3 is a 12-inch, high-contrast screen with a 3:2 aspect ratio and 2,160 x 144 resolution."
"Not only is it larger than the Surface Pro 2's 10.6-inch display, the 3:2 aspect ratio allows Surface 3 to display 6 percent more content than a typical 13-inch laptop screen."
