The DK2 prototype used a single 1080p display panel yanked from Samsung's Galaxy Note 3. But this time, something's different...

Instead of a smartphone display, Oculus has doubled your order! Two displays, mounted right to the lenses, adjustable with this knobby thing!

Until the day the eyePhone drops, this will do.

What's this? Looks like a face-detector an ambient light sensor, present to check if you're wearing the Rift, or perhaps to adjust display brightness to account for extra light leaking into the headset.
