The overall latency if about 50 to 60ms. It comes with 3 different pairs of lenses along with the ability to adjust focal lengths of the display. While DK1 offers a fairly immersive experience, it is not perfect. When using the device, motion blur is quite apparent. It also has the pixelation due to low resolution and the appearance of looking through a "screen door".
In addition to the head-mounted display, DK1 has a brick-like device called the control box. User must connect the HMD to the control box before it can be hooked up to PC. Along with various I/O ports such as HDMI, DVI, Mini USB and DC connector, Control box allows the user to change the brightness and contrast of his or her display. The video input for the HMD is DVI. The control box changes PC's HDMI output into DVI.
