== History and Development ==


Varjo announced the XR-4 in November 2023 as a significant upgrade to the [[Varjo XR-3]], offering dramatically wider field of view, inside-out tracking (eliminating external base stations), and lower pricing. The headset marked Varjo's transition from dual-display (micro-OLED + LCD) systems to unified 4K mini-LED panels while maintaining near-retinal resolution.<ref name="uploadvr">{{cite web |url=https://www.uploadvr.com/varjo-xr-4-hands-on/ |title=Varjo XR-4: Stunning VR With Disappointing Passthrough |publisher=UploadVR |access-date=2025-01-07}}</ref>
Varjo announced the XR-4 series in 2024 as their next-generation flagship mixed reality headset, succeeding the XR-3. The XR-4 was developed for demanding professional applications requiring photorealistic visual fidelity. Varjo was selected as the XR technology provider for the U.S. Army's Reconfigurable Virtual Collective Trainer program, using XR-4 headsets for immersive helicopter pilot training.<ref name="varjo">{{cite web |url=https://varjo.com/products/xr-4 |title=Varjo XR-4 |publisher=Varjo |access-date=2025-01-07}}</ref>
 
The XR-4 series includes three variants: the standard XR-4 for VR training, the Focal Edition with autofocus passthrough cameras, and the Secure Edition for classified government environments.<ref name="varjo">{{cite web |url=https://varjo.com/products/xr-4 |title=Mixed Reality Headset for Professionals – Varjo XR-4 Series |publisher=Varjo |access-date=2025-01-07}}</ref>
