    FPS is not related to refresh rate. The image of the movie is not refreshing, it's a just a sequence of a lot of images (frames), This is the monitor which refreshes and flickers (60Hz is low, 120Hz is fine enough).
    Don't confuse Hz with FPS.
    I'm aware of the difference, but missing your point, again.

    The relation between the content's FPS and monitors refresh rate is the end result. How can you say they are not related?

    Edit: My specific point about 48hz flicker is only with 24fps content. You cannot watch 60fps or 59.9Xfps content at 48hz on any mainstream TV.

    What if the camera sensor doesn't support 60 and 120 FPS video at those resolutions? Does anyone know what sensor is being used on the 1520? I could search about it.

    And the OIS wobble is probably a hardware defect, that's what I hear anyways.
    Well, theoretically, any camera sensor above 2 megapixels with the right ISP can do 120/720fps at 1080p. It's just a matter of software support.
    And the OIS wobble was supposedly linked to the CAF algorithms in Cyan. I'm really hopeful since they rewrote the entire Lumia Camera and with new algorithms it will go away. 4 second exposures are impossible right now :D

    According to what you write, you don't look to be aware of the difference.
    Movies are recorded at 24fps, but you watch them at 48/60/72/96/120/240 fps. Watching 24fps would be like watching a slideshow. Even when every frame is doubled, at 48fps, you can still see flicker.
    You cannot watch a movie on a 2+ times higher fps than it was recorded (actually you can, but the movie itself will run twice or much quicker).

    The relation between the content's FPS and monitors refresh rate is the end result. How can you say they are not related?
    What you say is about impression and experience, technically these two things are not related to each other (FPS is a software part, refresh rate is only related to the display).

    Well, to be honest: unnecessary feature, at least for now. 4K TV/Monitors still very expensives. Rather see features like, high-speed camera (120fps+).

    Sorry, what?
    Again, how is related refresh rate to the fps?

    Edit 1. You can even watch 120fps on 30Hz display. It will not be fine for the eyes and brain, but overall you will realize that the movie has higher fps.

    Are you aware that when you watch 24fps content on modern TV, frames are doubled, tripled, quadrupled, etc... to match the TV's refresh rate?? Watching 24fps on a TV that has a 48hz refresh rate, means every frame is doubled. At 72hz, every frame is tripled. At 96hz, every frame is quadrupled. At 120hz every frame is shown 5 times. And so on.

    24fps shown at 60hz goes through a process called 3:2 pulldown. Google it if you need to.

    Computer monitors and commercial TV are different. You need to specify between the two. Most people watch movies on TV.

    I dont think commercial TV accept a 120fps signal. And if they do, there's a very good chance the frames would be cut in half and viewed at 60hz.

    Ok guys, I'm confused here. Are pureview branded lumias(1520, icon/930) getting native support for 4k video recording with denim? Because I thought the feature was only available in moment capture mode where when you have to take a spontaneous shot, you instead film a short 4k video instead and later extract 8mp images out of it. That's MS's answer to verge reviewers who used to bash Nokia's imaging capabilities because they couldn't capture their kid's spontaneous moments. Lol.

    Ok, now that makes more sense, I didn't think TVs are so much different to monitors.

    Also, it'd be nice to get support for 120fps 720p and 60fps 1080p like most people said here.

    Yes they are, at least they should.

    Well, that explains why same movies seem more smooth and detailed on tvs than laptops.

    Blacklac, it must pain you to watch a movie in the theatres, right? The technology must feel ancient, like watching a flipbook.

    Lol. I actually never go to theaters. :D

    I think newer digital projectors use 48hz and 72hz though. 72hz is perfectly fine. I really only notice 48hz flicker on bright areas, usually white or skies, but it is distracting enough to take me out of the movie.

    We often dont realize when things are bad, if we are used to it. Ask someone who is used to PAL to watch NTSC (specifically 24fps content at 60hz) They will think we are stupid for using it.

    I'm talking film content. 59.9Xfps (sports, live TV) content is perfectly fine, IMO.
