All flagship smartphones should have 4K screens: Agree or Disagree?

2016-07-14
so let's cut to the chase I want 4k displays on phones there I said it and I'm not just talking about VR applications either I genuinely want all phone screens to have a high enough pixel density that no living human being on the planet could ever discern individual pixels from their phone screens no matter what the distance of the phone from their face is in many of our reviews you probably her to say that 1080p resolution at arm's length is fine it's fine totally fine and it is fine but fine isn't better fine isn't great fine isn't progress progress is progress there's the common knowledge idea out there somewhere around apples Retina Display a pixel density of about 326 pixels per inch when viewed at a distance of around 11 inches from the face that a human with 2020 eyesight can no longer discern individual dots I'm really nervous I'm gonna poke myself in the eye with this thing okay and that's actually accurate we can back that up with science but having 2020 vision doesn't mean you have perfect eyesight just that you've got acceptable visual acuity for a human being who lives on this planet when it comes to interacting with things like walking around or driving a car there's little reason to test beyond this 2020 standard if you've ever had your eyes checked and you've been able to read lines of text below where your optometrist stopped then chances are pretty good that you have better than twenty twenty eyesight also at no other time in history have so many people who were born with less than ideal eyesight been able to so easily correct their eyesight either through corrective lenses or through laser surgeries and this is definitely a more anecdotal point but I think a number of people would agree that they don't often consistently hold their phone exactly 11 inches or more away from their face if I'm reading reddit in bed for example chances are pretty good that I'm going to try and have my phone occupy as much of my field of view as I can if there are a number of people who have better than 20 20 eyesight and we can acknowledge that there will be times where we hold our phones closer to our faces then 11 inches away why are we quibbling about the minimum possible resolution needed to satisfy normal eyesight ok to nerd out on a little math and assuming a human being with the best possible eyesight and assuming that the closest minimum focusing distance away from the human faces around 4 inches that hypothetical human would be able to discern individual dots on a screen with a resolution somewhere around two thousand pixels per inch if an individual with that visual acuity actually exists they would be extremely uncommon and yet reading through the comments on a number of our videos i would estimate that around thirty percent of our audience has even better eyesight than that true story if we scale back that I site to normal 2020 but maintain that minimum focusing distance of around 4 inches we get over 800 ppi okay yeah that that is pretty close 800 ppi which on a 5.5 inch screen would roughly work out to somewhere around a you HD resolution the Sony Xperia z5 premium with a 4k display for example at a pixel density of around eight hundred and six pixels per inch that's it folks that's the absolute maximum for almost all of us now quad HD resolution screens 2560 x 1440 will largely address all of these pixel density issues for folks who care about such things the galaxy s7 screen is pretty dense 577 pixels per inch in I can't see any dots even with the pentile display and for many out there even quad HD is going to represent diminishing returns but instead of these incremental baby steps or sliding back and forth between good and very good why don't we just jump to the theoretical maximum more resolution doesn't hurt anyone who can't actually perceive it and there may be some folks out there experiencing phantom eye strain that they can't quite pin down from looking at lower resolution screens while trying to read text or look at fine details I have somewhere around 2020 eyesight and reading text on my tablet and then moving to a phone feels like a revelation it feels like a dirty screen protector has been pulled off of the world and we're likely moving into a future where we use more virtual and augmented reality applications which might push our phone screens closer to our eyes naturally or require the use of magnifique patient yeah I want this folks you HD screens on phones I think it's time I think we're ready and now I patiently await all of the politely and respectfully worded comments we're sure to receive telling us just how wrong you think I am as always folks thanks so much for watching be sure to subscribe to this channel for more fun editorials like these and hit that thumbs up button for a little extra positive reinforcement for pocket now I'm Juan Carlos pagnell you can chat me up on Twitter and Instagram as some gadget guy and I will catch you all on the next video more resolution doesn't hurt anyone who can't actually
