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 Aero''' is a professional PC [[virtual reality]] [[head-mounted display]] developed by [[Varjo]], released in October 2021 at $1,990 USD. Designed for high-end consumers and professionals, the Varjo Aero features ultra-high resolution mini-LED displays at 2880x2720 per eye, 115° horizontal field of view, built-in eye tracking with automatic IPD adjustment, and Variable Resolution technology for optimized performance. Using SteamVR 2.0 tracking and featuring active cooling, the Aero brought Varjo's professional-grade visual quality to a more accessible price point compared to their enterprise XR-3 and VR-3 headsets.
