Since the presentation of Apple Vision Prowe are discovering more details about the brand new device that were not disclosed in the opening keynote of WWDC23. Regarding the device’s screens, information such as resolution (more than 4K in each eye) and size (each with 1.41 inches) were commented on, but other issues were left out.
It is noteworthy that, despite the very high resolution, the display production chain analyst Ross Young even speculated, before the event, that the screens would reach a density of 4 mil dots per inch. He himself, however, rectified the forecastsaying that the headset screens appear to reach around 3,4 mil dots per inch.
A very important point is the update rate of the display, something especially important when dealing with virtual/augmented reality devices. By not using the term ProMotion to refer to the Vision Pro screens, Apple tacitly stated that they would not reach 120Hz like the iPhones 13 Pro, 13 Pro Max, 14 Pro and 14 Pro Max, although it has not commented on the matter. in the presentation.
The doubt, however, ended with a WWDC session on content reproduction in spatial computing experiments. Early on, it is already said that headset displays work, most of the time, with an update rate of 90Hzgetting at 96Hz when playing content at 24 frames per second so that it scales with a rate that is divisible by 24.
The screens of most devices run at a rate of 60Hz, including most iPhones and computers. Higher rates provide greater fluidity and visual comfort, which is even more important in the case of visual computing. Still, 90Hz should be enough for a satisfying AR/VR experience.
Compared to competitors, the Vision Pro’s refresh rate is average and slightly below some models. O Playstation VR2 and the Meta Quest 2for example, run at 120Hz, while the Valve Index reaches 144Hz. Other devices, on the other hand, such as the Meta Quest Pro and the HTC Vive XR Elitealso work with a 90Hz screen.
Interestingly, according to another WWDC session, the headset is always rendering and updating the displayed content, even though the open application itself has not been updated. Along with this, spatial algorithms and the lens included in the hardware of the device make the experience more dynamic and immersive.
In the speech itself, the fact that all this rendering requires a lot of processing power from the Vision Pro is highlighted. While the device is powerful, the guidance to developers underscores the fact that care must be taken with excessive layers and elements so as not to overload the headset or drain too much power.
With less than a week after the initial Apple Vision Pro presentation, we should still hear a lot about the device until its launch and the start of sales, which will only occur in early 2024. Until then, there will be a lot of new information and gaps filled about the device.
