I guess 120Hz mobile screens are in the "soon" category now? http://www.blurbusters.com/mobile-120hz-ips-displays-for-smartphones/ http://www.blurbusters.com/m

I'd be quite interested to see one for myself and get an idea whether it makes for a noticeably smoother experience. I expect there will be a lot of trouble getting software to reliably hit that number, though, especially Android...

Somewhat related: VR apps will likely require more than 60fps, definitely more than 30fps, diminishing returns beyond 120fps (see 3min interview w/ Palmer Luckey, Oculus VR founder: https://youtu.be/BQoPvZGjYvQ https://youtu.be/BQoPvZGjYvQ).

Even with a 60 Hz screen this will be advantageous. If the application is fast enough to render at 120 fps, rendering at 60 fps means that the UI thread will be idle at least half of the time, so the processor will draw less battery power.

  I don't get it. How will you achieve enabling your application to render at 120 fps, instead of 60 fps, without leveraging a twice as powerful CPU/GPU, which will use roughly twice as much power? I would think the added power draw from rendering at 120 Hz would come from all the applications needing double the number of graphics-calculations they need at 60 fps.

How will you achieve enabling your application to render at 120 fps, instead of 60 fps, without leveraging a twice as powerful CPU/GPU, which will use roughly twice as much power? By making it twice as efficient. Partially by using fewer cycles to compute but probably largely avoiding tiny waits that waste power without computing.

Also, rendering at 120Hz allows you to motion blur the UI on 60Hz screens very simply.

I hope so, 120Hz screens would be nice for VR. I think Samsung's latest Super AMOLEDs already have 90Hz or so.

whats the point of 120Hz screen when you have 100ms touch input lag?

  At least scrolling and zooming animations can be smoother even if they aren't quite caught up with the finger. shrug

At least it makes more sense then 4K in 5" size factor.
