iFixit experts have published the second partdisassembly of the Apple Vision Pro mixed reality headset. This time, experts focused on the gadget's two screens, wondering whether they really support 4K resolution. Experts also assessed the device’s maintainability.
Experts have determined the dimensions of each headset panelVision Pro, and using a microscope to measure the size of each pixel in these displays. This ultimately made it possible to determine the resolution of the headset screens. It is 3660 × 3200 pixels.
By definition, 4K resolution is 3840 x 2160pixels. Thus, the Vision Pro display resolution is slightly lower horizontally and significantly higher vertically. Despite this, iFixit specialists were impressed by the Vision Pro screens, which they described in their video.
“These values do not quite correspond to the concept of 4Kaccording to commercial standards, but the same 4K TVs also do not meet them. In short, each of these panels has more pixels than a 4K TV, but they aren't technically 4K displays. We also calculated the pixel density per inch (PPI). It amounted to 3380 PPI. In short, 50 Vision Pro pixels will fit into one pixel of an iPhone smartphone display,” the video says.
iFixit experts also calculated the valueangular resolution of Vision Pro displays or pixels-per-degree (PPD) of view, which some consider a more important metric for virtual reality headsets than pixel density per inch. The Apple Vision Pro headset had a PPD of about 34 pixels per degree at a viewing angle of 100 degrees. Compared to the Quest 3 VR headset from Meta✴, the Vision Pro has a slightly lower viewing angle, but the image quality is noticeably higher.
iFixit also assessed Apple's maintainabilityVision Pro, giving the headset 4 points out of 10, but calling this rating preliminary. When disassembling the headset, it turned out that it practically does not use combined components and all the elements in the headset are modular, which increases its maintainability. The experts explained their low rating as follows:
«Хотя внутрь устройства попасть сложно — спасибо, Apple School of Engineering on Adhesive and Glass - I was surprised to find that the headset had a complete lack of mating parts. Even the earphone speakers and bands are modular in design and don't appear to be paired together. Yes, we had some problems when we tried to install screens from one device to another, but I think this problem has more to do with the issue of personal fit of the device rather than the complexity of the design. The headband and seal are also completely modular, which shouldn't be taken for granted when recalling the Valve Index headset with a non-removable rear headband pad. Now about the disadvantages. The front glass and OLED panel cannot be repaired. The battery pack is tightly sealed and it is almost impossible to open it without damage. And it's unlikely that Apple will issue replacement parts and manuals for self-service of this device, unless you take into account the additional battery and light-protective sealing pads, which are sold separately,” the iFixit review concludes.
