Valve Index

ABOUT:

OPTIMIZED PIXEL LAYOUT
The headset's dual 1440x1600 RGB LCDs provide 50% more subpixels than OLED, resulting in greater sharpness for the same rendering cost. In addition, the fill-factor is three times better than OLED, greatly reducing “screen door” effect.

HIGHER FRAME RATES
The Valve Index® Headset runs at 120Hz with full back-compatibility to 90Hz, as well as an experimental 144Hz mode. Higher framerates improve realism and optical comfort, allowing longer and more comfortable play sessions.

EXTREMELY LOW PERSISTENCE
Valve Index displays have a reduced illumination period of 0.330ms to 0.530ms (framerate dependent), allowing imagery to remain just as sharp when your head is in motion as when you're standing still. This is a 5x improvement over first-generation PC VR HMDs.

OPTIMIZED FOR FOV
The best way to improve field of view is to position the optics as close as possible to the eyes. Physically adjustable IPD (distance between eyes) and eye relief (distance from lens to eye) lets you optimize the field of view for your face. With these features, as well as the dual-element lens and canted optics, this headset provides 20° more FOV than the HTC Vive for typical users.

DUAL-ELEMENT LENS
The custom lenses built into the Valve Index Headset maximize field of view without sacrificing edge-to-edge clarity. High geometric stability allows you to look around the scene by moving your eyes (not just your head) with minimal shape distortion.

CANTED OPTICS
Instead of a mount perpendicular to the user’s eyes, the headset’s displays cant outward by 5 degrees. This improves outer FOV while balancing the inner FOV.

OFF-EAR IMMERSION
Designed to provide a more natural way to experience audio, Index Speakers do not touch the ears, allowing sound to freely flow and interact with the geometry of your own head and ears. With this earspeaker design audio feels greatly externalized - virtual sound sources appear to come from the environment around you, rather than from inside your head.

LONG-SESSION COMFORT
No physical contact means cooler temperatures and a huge improvement in comfort, no matter how long you play. Each speaker's position is also adjustable and can be moved to the audio sweet-spot for all heads.

ULTRA-NEARFIELD FLAT PANEL SPEAKERS
The composite honeycomb-panel speaker drivers in the Valve Index provide their full-frequency range across a nearly 180-degree dispersion pattern. This allows us to accommodate the widest possible diversity of ear and head shapes without sacrificing sound quality.
