  • The HTC Vive includes a display featuring two 1080 x 1200 screens, one for each eye, and the pixel density is said to eliminate the screen door effect unless you really look for it.

    This gives the Vive a total resolution of 2160 x 1200 pixels, and an aspect ratio of 9:5 as opposed to other headsets' more standard 16:9. The result is a taller image, but one which feels more natural and convincing – you can look up with your eyeballs rather than by craning your neck.

    The screens run at 90Hz, which is on a par with Oculus Rift but lower than the 120Hz of Sony's Project Morpheus. Whether the difference will be noticeable remains to be seen, but we suspect that once you get into the realms above 90Hz gains are marginal.

    There's also a front-facing camera, which means the real world can be overlaid onto the virtual. In terms of gaming this opens up new possibilities for augmented experiences, but critically it will also help users move around their real-world environments without removing the headset.
