VR goes crazy over the past couple of years, and this one goes even further. The Valve Index headset delivers an immersive and high fidelity virtual reality experience with advanced visuals via a pair of 1440 x 1600-resolution RGB LCDs, faster 120Hz screens, an IPD slider to adjust the distance between your eyes for a better fit, and a pair of small speakers specifically designed not to touch your ears, in the sides of headphones. The tethered headset will allow you to walk around a 10-meter room in VR mode.

Fidelity first
The Valve definitely pushed visual, audio, and ergonomic technologies to create the best-in-class VR experience. Fidelity means high definition visuals and clarity as never seen before.
* Optimized pixel layout. The headset’s dual 1440×1600 RGB LCDs provide 50% more subpixels than OLED, resulting in greater sharpness for the same rendering cost.
* 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.

Fine-tuned lenses offer the sharpest, widest view across the eye’s full range of travel.
* Optimized for FOV. The best way to improve the 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 a lens to an 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.
