The [[Varjo XR-4]] is a professional [[PC-Powered VR|PC-powered]] [[mixed reality]] and [[virtual reality]] [[head-mounted display]] announced on November 27, 2023, by [[Varjo|Varjo Technologies]].<ref name="varjo-xr4-product" /> Representing the fourth generation of Varjo's mixed reality technology, the XR-4 series eliminated subscription requirements, introduced inside-out tracking as standard, and offered professional-grade specifications at a revised price point for its class.<ref name="varjo-announcement" />
==History==
The XR-4 development began in 2022 following feedback from [[Varjo XR-3]] customers and success of the subscription-free [[Varjo Aero]]. Key development goals included democratizing professional mixed reality, aiming for high visual fidelity in both virtual and passthrough modes, and eliminating external tracking requirements.<ref name="cnbc" />
===Major Improvements over XR-3===
*51 PPD uniform resolution (vs dual-display system)
*20-megapixel [[passthrough cameras]] (vs 12MP)
*[[Inside-out tracking]] standard (vs external base stations)
*Significant price reduction for the standard model with no subscription
*Passthrough resolution of 33 PPD (Standard Edition) or 51 PPD (Focal Edition)


The '''Varjo XR-4''' is a professional-grade [[mixed reality]] [[head-mounted display]] developed by [[Varjo]], announced in October 2023 and released in November 2023 at a starting price of $3,990. Designed for enterprise and professional applications, the XR-4 delivers what Varjo describes as "human-eye resolution" with 51 pixels per degree across the entire 120° × 105° field of view, powered by dual mini-LED displays with combined resolution exceeding 28 million pixels. The headset features industry-leading passthrough quality through dual 20-megapixel RGB cameras, integrated 200Hz eye tracking for dynamic foveated rendering, and extended-range LiDAR for accurate depth sensing. Notably, the XR-4 eliminates the subscription requirement that was mandatory for previous Varjo headsets, making the premium hardware more accessible to professionals.
