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 [[mixed reality]] [[head-mounted display]] developed by [[Varjo]], released in November 2023. The headset features crystal-clear 4K-per-eye mini-LED displays with 51 pixels per degree, 120° × 105° field of view (50% wider than predecessors), 200 Hz eye tracking, and 300 kpix LiDAR for advanced mixed reality. The XR-4 uses inside-out tracking and a fiber-optic cable for ultra-low latency. Priced at $3,990 (down from $6,495 for XR-3), it targets enterprise applications in training, simulation, and design visualization.
