No, I don't think that's true. While it's true that increasing frame rate will increase effective (as it appears) spatial resolution, it's not true that increasing spatial resolution decreases effective frame rate.
You'll notice the lack of frame rate more, as you notice each frame more. Without increasing the rate, you'll get a higher pixel resolution image of motion blur at whatever the shutter setting is, when anything, including the camera moves. To really gain from the increased spatial resolution, with moving images, you need to increase the frame rate, so you get less blurring. If you just shorten the shutter time you'll get even worse judder/strobing.

Which is what most of my post said, but which you didn't quote. Larger screen sizes increase the jump between each frame.
There is a new resolution standard on the horizon, so we're now changing everything anyway.
True but it's because it's especially needed for the reasons described. The tests they will have done, and are still doing for UHDTV, show it's needed.Edited by Joe Bloggs - 7/27/13 at 10:51am
