A Few Thoughts On True Tone

Back when I received the 9.7" iPad Pro I published some of my thoughts regarding the True Tone display technology. And while I won't really be going over the topic in great detail again, I do have some additional thoughts on the technology after having using the new iPad Pro for quite some time.

Something I wanted to clarify from my original article is the purpose of my greyscale measurements. Some readers interpreted it as evidence that True Tone didn't work as intended. In actuality True Tone works exactly as intended by providing good relative accuracy. As you move to different environments the color temperature of the display shifts to match how your eye adjusts its perception of white depending on the temperature and brightness of the light around you. This obviously leads to inaccuracy relative to the sRGB standard, but that's missing the point of True Tone entirely. My tests were simply meant to demonstrate how much shifting occurs in different environments, along with a clarification on some misunderstandings I had heard regarding the relationship between True Tone and the DCI-P3 gamut, which are really unrelated technologies.

True Tone works very well, and in a way Apple has proven me wrong here because I was initially skeptical. I've seen this attempted before, particularly by Samsung, and the implementations have not been good at all. When I first got the 9.7" Pro I felt like the True Tone mode shifted too far toward the red. However, after using it for some time I began to realize that this was the product of me using other devices that all shift toward blue, which ruined my perception of the display. When using the iPad Pro on its own for reading or doing work, pulling out another device with a blue shifted display is absolutely jarring, as the iPad has adjusted to match how my eyes perceive things in different lighting, while all my other displays are forever blue. In a way, the biggest problem with True Tone is that it's not in everything, and I think this is something Apple should be bringing to all of their portable devices. 


Apple's Simulated True Tone Image

It's difficult to photograph True Tone, as depending on where your camera's white balance lands the iPad Pro will look too red, or the other display will look too blue. I really recommend checking out True Tone for yourself, although if you decide to do it in an Apple Store you probably won't see the benefits because Apple's other products are designed to look neutral under the same sort of fluorescent lighting as those stores. If you have a chance to try the 9.7" iPad Pro outdoors or somewhere with warmer lighting I think you'll see why this tech is one of the small things that nobody really asks for, but everyone appreciates once they have it.

    "The 9.7" iPad Pro does well in 3DMark's graphics test, but like Ice Storm it doesn't do well in the physics test. It seems that this test is programmed in a similar way to Ice Storm, and in that sense I'm not sure how representative the physics test is of real-world performance "

    The physics test conveys utterly no information. If you look at the code, it's obvious that the physics score basically scales as frequency*numberOfCores. So those octacore CPUs get their one (and only...) chance to shine.

    But all you're learning is something you already knew --- that the SoC has lotsa cores running at a high frequency. You're learning nothing predictive about how those cores behave on real code.
    An analogy is to judging an SSD by its interface speed --- "ooh, it supports PCIe3x4 --- obviously it must run at 4GB/s under any and all circumstances", or to assuming that the only number you need to know about a memory system is that it connects to DDR4@2400.

    I find the NAND performance numbers very interesting when compared to that tiny new Samsung BGA SSD:
    http://www.anandtech.com/show/10385/samsung-begins...

    Sure the Samsung numbers are perhaps 3x higher (given different testing methodologies, etc) but I suspect the Samsung volume and power are SUBSTANTIALLY higher. So Apple is doing remarkably well. It would be interesting to know if they are using tricks like TurboWrite (ie use part of the flash as pseudo-SLC) or if that's still on the table, available for next year's performance boost.

    Very useful review. Because my own habits may differ from other users, I'm still unsure as to whether I should spring for this new one of try to find an Air 2 (hopefully one with 64 gigs rather than the 16 Apple is offering direct). It seems a bunch of the benefit from the Pro is the camera, which is something I just don't care about.

    If they had given this the 4 gigs of RAM in the larger Pro, it would be a no brainer for me. I feel like Apple always holds back on the RAM (and tells us we don't need it), which obsoletes their devices quicker than I would like.

    In general apple holds back so they get you to upgrade it's a business model it's the way it has to work or you'll be keeping your iPad forever. IN my opinion, I think even if you had a first generation Erewhon is aware the tablet to hold onto. You really have to ask yourself this is it worth spending $600 more not counting the pencil for an additional hundred or the keyboard for an additional 150 that's if you're talking about their base model if you're going be on that then you have to ask yourself if it's worth spending closer to seven to $800. What do you use your tablet for now? Do you find it slow? Have you went to the store and did a side-by-side such a Staples Best Buy or Apple? I would recommend doing that use them a little bit or even go as far as biting the bullet and buy an iPad Pro from Bestbuy demo them side-by-side on the weekend and decide then whether you going to keep it or return it. Depending on where you're from your givien A window of I believe 14 days to return at least a Best Buy it might be an option for you to try them of them both, but your conclusion and stick with it

    DisplayMate measures "lowest reflectance" but this is the best only for glare displays. Tablets with semi-matte, capacitative touch display must have a much lower reflectance but, unfortunately, so far come with 16:9 or 16:10 display ratios.

    I wish a Windows tablet with matte, semi-matte or current iPad-like low reflectance display; iPad-like display ratio, casing, weight, battery duration; battery replaceability or service; great WLAN range; BGA SSD; USB and thunderbolt 3. Still the manufacturers of Windows tablets fails to offer displays suitable outdoors with an acceptably low display ratio and a casing suitable for hours of hand holding.

    Many iOS apps do not help if the needed functionality is not available; I find it only for Windows or maybe Linux. This and the missing general file management under iOS mean that 2/3 of my tasks incl. productivity (other than simple proofreading) is impossible on iPads. Therefore the iPad Pro 9.7 is too expensive. Its good hardware can never compensate the failure of iOS and apps. This may be different for some needing only mainstream apps and file formats.

    i would buy it but its waaaay to thick for me...totally unacceptable

    Is this sarcasm?

    the best tablet ? I dont think so , Core M3/5/7 Tablets are better and with full windows 10

    Have you actually used them as tablets? The SP4 is a terrible tablet. It's heavier, it's stuck in landscape, it lacks a lot of touch-optimized apps, it has an inferior screen, and it has inferior battery life.

    Oh, but Windows, you say. That's great. To get a decent Windows experience laptop out of it, you're spending $1200 for everything, and a $999 Razer Blade Stealth smokes the half-assed laptop that is the SP4, leaving you with $200 to buy an Nvidia Shield Tablet K1, which is still a better tablet experience than the SP4.

    Have you used Surface as a tablet, though?

    I'm using SP3 as my main tablet and laptop. It is stuck in landscape only if you want to use kickstand. If you want to hold it in your hands, it works in portrait just fine. Since I love kickstand, only scenario I use it in portrait is for comics, which I read in app called Cover. Everything else I do in landscape, and even with heavier hardware, being able to use tablet with one hand (while it sits on my lap or on bed, table... at angle I like) while having the other hand free to hold a cup, glass, sandwich... is more than worth extra weight.

    I have all the apps I need for tablet mode. Granted I'm not too demanding with apps, but usual stuff - browser, mail client, FB, maps, weather, FB messenger and Skype, YouTube player, News client, comics and ebook readers, music and media players... are all there and perform well under touch.

    I can get 8 hours of light usage out of fully charged Surface Pro 3. Most common scenario, browsing, will fluctuate wildly, but hit usually comes with Flash-heavy sites. Not sure if I can open them on iPad at all. And then, there's very nice type cover sitting in vicinity - if at any moment I decide that whatever casual I do will require some serious typing, transformation is 1 second away.

    As a laptop - surprisingly enough, SP4 released keyboard (which works with SP3, too) is one of finest laptop keyboards I have ever used, and even touchpad is quite good - maybe not on MB level, but as good as any Windows laptops does... and I still get to use touch screen, which I do. I wouldn't like touch screen on my desktop's screen, but on small screen that usually sits closer to me than desktop, it makes a lot of sense.

    My SP3 also has full Office, Photoshop, Lightroom... among few other desktop programs. I'm using desktop for really heavy lifting at home - and gaming - and SP3 replaces laptop and tablet very nicely for me, at home and on travels. iPads are nice - I'm buying them for my mother every 2 years or so - but they just can't replace both laptop and tablet for me, and since I live in NZ - almost every trip is intercontinental, and having one device less to drag is easily noticeable.
