The '''Arpara 5K VR''' is a PC [[virtual reality]] [[head-mounted display]] developed by [[Arpara]], released in 2022 starting at $399. The world's first 5K dual micro-OLED (OLEDoS) VR headset, featuring 2560x2560 per eye resolution (5120x2560 combined), 3514 PPI density, 1,000,000:1 contrast ratio, 1 μs response time, DCI-P3 90% color gamut, ultra-lightweight 200g design (tethered version), and diopter adjustment from -1D to -5D. Available in tethered PC VR and standalone All-in-One versions.
The '''Arpara 5K''' is a high-resolution [[virtual reality]] [[head-mounted display]] developed by [[Arpara]], launched via a successful Kickstarter campaign in 2021 and shipping in 2022. Marketed as "the world's first 5K micro-OLED all-in-one VR headset," the Arpara line features dual 1.03-inch micro-OLED panels from SeeYA with 2560 × 2560 resolution per eye (5120 × 2560 combined), an exceptional 3514 PPI pixel density delivering 32 pixels per degree, and 1,000,000:1 contrast ratio with DCI-P3 90% / sRGB 127% color gamut—all at an ultra-low 2μs display response time for virtually zero motion blur. Available in two versions: the ultra-lightweight Tethered 5K (200 grams, 3DoF base) for PC VR, and the AIO 5K (380 grams) powered by Qualcomm Snapdragon XR2 with 6DoF inside-out tracking, hand tracking, and 4600mAh battery. Both versions feature a 95° field of view, 56-72mm IPD adjustment, built-in -1D to -5D diopter correction, and support for variable refresh rates up to 120Hz. An optional SteamVR tracking adapter enables full 6DoF with Valve Index controllers.


== History and Development ==
== History and Development ==


Arpara launched a Kickstarter campaign in 2021 for what they claimed was the world's first 5K micro-OLED VR headset, exceeding their funding goal within 15 minutes. The tethered and AIO (All-in-One) versions began shipping in March 2022. Arpara used OLEDoS (OLED on Silicon) displays from SeeYA, making it the first consumer VR headset with this technology. The compact form factor and high resolution targeted enthusiasts seeking premium visuals.<ref name="kickstarter">{{cite web |url=https://www.kickstarter.com/projects/969477673/arpara-worlds-first-5k-micro-oled-all-in-one-vr-headset |title=Arpara 5K Kickstarter |publisher=Kickstarter |access-date=2025-01-07}}</ref>
