Oculus Rift DK2
The Oculus Rift DK2 is a VR headset from Oculus. It has an HDMI port and works with desktop and laptop computers. It works with Windows, Linux, and Mac. It has a flat focus. Its design is a refinement of the Oculus Rift DK1. It has higher resolution than the DK1. It is a more basic headset compared to the Oculus Rift CV1.
It has larger lenses than the DK1. The lenses are made of a material like polycarbonate or PMMA.
It uses a display originally specified for the Galaxy Note 3 smartphone.[1]
The DK2 has the same foam facial interface as the DK1, meaning it is the same shape on the user's face.
The DK2 has support for P 'n O tracking using constellation. Alternatively, it can be used with only rotation tracking using its built in IMU.
It has an IPD of 63.5mm.[2][3]
The Oculus Rift DK2 design files are open source at Github.
Positional tracking[edit]
DK2 has an external camera that tracks the user's position. Within the camera's view, it tracks an IR LED array in the front part of the headset to capture your head's position and movement within the 3D space.

The DK2 uses HDMI 1.4b.[4]
