Pimax 8KX

From VR & AR Wiki


The Pimax Vision 8KX is a high-end PC VR head-mounted display developed by Pimax, released in 2020. It was the world's first consumer VR headset to feature dual native 4K displays (3840×2160 per eye) and became famous for its ultra-wide 200° diagonal field of view—approaching natural human vision. The 8KX won Digital Trends' "Top Tech of CES: AR/VR" award in January 2020 and remains popular among simulation enthusiasts for its unparalleled clarity and field of view in racing, flight, and space simulations.

History and Development

Pimax unveiled the Vision 8K X at CES 2020 in January 2020 as their flagship headset, building on the earlier Pimax 8K which used upscaled 4K displays. The 8KX marked a significant advancement by running both panels at native 4K resolution without upscaling, delivering unprecedented clarity for a consumer VR headset.[1]

The headset uses SteamVR Lighthouse tracking, maintaining compatibility with existing HTC Vive and Valve Index base stations and controllers.[2]
