Is iPad Pro's 120hz a true effective refresh rate?

    like the title says, does anyone know if the refresh rate is actually true 120hz, or is it an artificial one like most TV manufactures seem to do; where it's 60hz but uses the processor to artificially bump it up higher?


    Kallum.

    It's variable. It can be up to 120Hz (i.e. you're scrolling in Safari), but it can also clock down to 24Hz for 24fps content.

    It's not motion-interpolation, that bad artificial processing found on almost all HDTVs these days.

    I hate that and turn it off on my TV, otherwise everything looks like a budget Australian soap opera.

    Yup, me too. You don't have to worry about that effect with the new iPads w/ProMotion. Just incredibly smooth scrolling that makes older models look very "stuttery".

    Yep it certainly is smooth... every one of my other devices looks laggy now :(

    That's the first setting I turn off before I calibrate a tv.
    Ugh. Awful.

    The interpolation you talk about is really only something you even want to consider when you are dealing with fixed content like video.

    With games and apps, it's cheaper to ask them to render the extra frames than it is to interpolate. Games are still pretty expensive, but a "good" interpolation algorithm is too. Although I will point out that just because the screen can do 120Hz (like a TV), you don't have to render at 120fps (like a TV). Games can still aim for 30/60fps if they want here.

    There's a couple cheap benefits here though:
    - Most apps should be able to adapt to 120fps easily, and automatically. Apps don't need to render a whole lot extra to hit the higher frame rate.
    - 24fps content doesn't have issues with 120Hz displays like it does with 60Hz displays. 3:2 pull down either introduces blended frames, or a sort of stutter because each frame isn't displayed for an equal amount of time. I've enjoyed that benefit with a couple streaming apps already like Netflix.

    I take it a step further. When I'm at people houses I disable it when they're not looking :)
