Valve appears to have accidentally leaked several videos demonstrating how to unbox and set up its upcoming Steam Frame virtual-reality headset. The clips briefly appeared on the ARM Steam client following an update before being pulled, offering an unusually detailed preview of the device ahead of its official release. This matters because Valve has yet to confirm an exact launch date, and the leak, alongside other recent signs, suggests a release could be imminent.

The videos show how to adjust the headset using its "pivot arms", insert a spacer for glasses wearers beneath the face gasket, and connect the wireless dongle to a PC or Steam Machine for game streaming. They also detail an "Ergonomic Accessories Kit", featuring hand straps, a top head strap for stability, and an extended light blocker for smaller noses. The Steam Frame itself features 2160 x 2160 resolution LCD screens per eye, a Snapdragon 8 Gen 3 chip and up to a 110-degree field of view; Valve had previously targeted a summer launch, and a recently reported 13-tonne shipment of headsets adds to speculation that release is close.
