'''DPVR E4''' is a [[virtual reality]] [[head-mounted display]] released in 2023.
The '''DPVR E4''' is a PC-powered [[virtual reality]] [[head-mounted display]] developed by Chinese company [[DPVR]] (DeePoon VR), released in 2023 at $499. Positioned as an affordable entry into high-quality PC VR gaming, the DPVR E4 offers specifications competitive with more expensive headsets: a 3664 × 1920 resolution Fast LCD display (1834 × 1920 per eye), adjustable refresh rates up to 120Hz, a wide 116° diagonal (94° horizontal) field of view via Fresnel lenses, and 6DoF inside-out tracking with four cameras—all while weighing just 280 grams with a convenient flip-up visor design. The headset features 54-72mm hardware IPD adjustment (expandable to 50-80mm via software), space for glasses wearers, and controllers with design and layout similar to Meta Quest 2/Oculus Rift for broad SteamVR compatibility with over 7,000 games. The DPVR E4 Black variant adds an enhanced "Turbo Cooling System" that reduces core temperature by 20°C for longer gaming sessions, along with a reinforced cable for improved durability.
