When Apple unveiled its first Retina display with the iPhone 4 in 2010 , it had an insane 326 pixels per inch , whichSteve Jobs describedas “ comfortably over ” the human retina limit of 300 ppi . With Vision Pro , Apple has blown the doors off of Retina to make a show that fits around 54 pixels into a exclusive iPhone Pixel .
According toiFixit ’s in - depth analysis , the Vision Pro has a pixel density of 3,386 ppi , which is “ a badly high - res exhibit , ” but not technically 4 KB , which clocks in at 3,840 pixels wide-eyed . However , iFixit says it ’s “ the highest - density display that we ’ve ever find out , ” besting the HTC Vive Pro ( 950 ppi ) and Meta Quest 3 ( 1,218 ppi ) .
As iFixit and Steve Jobs explained , pixel concentration has as much to do with picture element per in as it does the distance the concealment is from your eyes . Because the screen are so close to your eyes , VR headsets metre expose inpixels per degreeto generate “ angular ” resolution , which iFixit estimates at 34 ppd , about the same as a 65 - inch television .
The rest of the teardown covers thing like the stamp battery , which uses three iPhone - shelling - sized mob stack atop each other connect in series , sensors , and chipping , and specify that “ there ’s a good deal to like here ” when it comes to quicken and replacing humbled part . However , Vision Pro still begin a comparatively low repairability account of 4 out of 10 due to its replaceable battery , and magnetized lenses and light seal .
iFixit consider there is much room for advance : “ Our hope is that , by the time these things get wince into a span of eyeglasses , repairability wo n’t be something tacked on at the end , but a fundamental design tenet . If face goggles really are the future of computation , then we need to get this right from the very beginning . ”
