    Why is no one talking about this? This is the biggest news in the mobile space in years! Is it always 120hz, or just in certain apps? Is there any sort of adaptive sync going on? I'm struggling to find anyone talking about this for some reason.

    Maybe because no one really understands what impact it'll have. Sounds nice in theory, but I need to see it for myself. The iPad Pro as it is is already super smooth.

    It's 120hz, it'll be the same as a monitor. 60hz is okay, but once you experience more it's stuttery.

    Is there any info at all about how often it's at 120hz? I hope constantly, that'd be a game changer.

    Think we have to wait until the Displaymate and Anadtech etc folks gets hold of these to get the proper detailed tests to determine the overall tech involved, never mind the regular reviews to determine the day to day impact of the seeming upgrade.

    During the keynote they said the 120hz refresh rate would be used when performance would benefit. Looking at a still photo (I think that was the example) wouldn't be improved by the higher rate. So, the refresh rate would be reduced on a still image to improve battery life.

    Yep. They showed varying refresh rates (24Hz, 48Hz, 120Hz) depending on task.

    It's probably for when you're using the pencil. They talked about how 120Hz is great for a 20ms latency so it might just kick on when it senses you're using the pencil.

    I hope this isnt the case.

    It probably isnt, 120hz looks fenomenal in anykind of motion, be it scrolling and animations. This is retina tier upgrade.

    I think it does it whenever there's motion since the keynote mentioned it's buttery smooth when scrolling.

    Of course, for watching videos, I reckon a different refresh rate would probably apply unless they do motion interpolation.

    This is a game-changer. Just wait until you experience it and you’ll see what I mean.

    120Hz is a big deal.

    Especially for the Apple Pencil. They've reduced the latency from 50ms to 20ms.

    Oh, I know. My only concern is if the GPU has enough muscle to deliver those frame rates at those resolutions (~5.6 million pixels on the 12.9" iPad).

    #1. 120hz is not always active probably not user selectable.
    #2. Keynote said make Scrolling more Fluid. And Movies better.
    #3. 50ms to 20ms will be amazing. Since it takes 400ms for your eyes then brain to detect a change and send a response to your muscles.
    #4. I highly Doubt 120hz will make it to the IPhone 8

    So which tablets have you used with 120 to make that statement? Some people turn it off on TV's because it makes some movies and other videos look terrible.

    I wonder how some action games will look like on 120Hz

    What was the latency on the old iPad pros?

    /oh sorry I just read it, they cut it more than half, wow

    IPP -> IPP2 looks very similar to iPad2 -> iPad3. IPP2 has much better 120hz screen that takes all the increased gpu just like iPad2 vs iPad3 did. Im not saying IPP2 is the new iPad3, but there are a lot of similarities.

    It will depend on the task. If you're watching a movie that has 48Hz refresh rate, having a 120Hz won't change anything.
    But when you're scrolling in safari, for example, the 120Hz refresh will look beautiful! Or the menu animations etc.

    Actually movies will look even better because they're shot at 24p so now that'll be native for movies. I won't go more into it than that. You can look up more specifics.

    But overall 120hz is much better for movies too

    You do realise pretty much no TV is over 60hz, right? They use frame interpolation which isn't even close to a native 120hz display.

    You're confusing refresh rate with motion interpolation.

    I think this could be huge and was one of the main reasons I purchased the 10.5. Looking forward to how animations, scrolling, etc. work at this new refresh rate.

    Do you think it be implemented on the iPad pros running iOS 10 that will be arriving next week? Or is it an iOS 11 feature only?

    Exactly, it's two completely different things. One is a marketing gimmick aimed at morons (sorry :) ) the other is a real, tangible improvement.

    My PC monitor is a 144hz GSync, used primarily for gaming, but for desktop use it's notably smoother than 60hz.

    120hz is better for movies at 24p, because 120 is directly divisible by 24, meaning there's no pull down effect from displaying some frames 3 times instead of two, thus less stuttering and smoother motion. Hardware/software has got a lot better at faking this when the panel is 60hz, but 120hz removes the need for the extra processing. Which is my limited understanding anyway. What I do know is I can see the difference, heh.
