During a panel at the recent SXSW festival, Oculus VR’s Nate Mitchell announced that the latest prototype of the Oculus Rift headset (Crescent Bay) uses two OLED displays – not just one. It was revealed at CES this year that Crescent Bay used an OLED display (widely thought to be the same 2560 x 1440 unit used in the Galaxy Note 4). Per-eye resolution is much higher than in the Dev Kit 2 (which split 1920 x 1080 resolution between both eyes) because of this.
