Ive got the new 10.5 iPad Pro and it's great, but I kind of expected ProMotion to blow me away. It doesn't feel as crisp as they seemed to market it. Swiping between pages of apps is *better* than on my old iPad Air 2, but the apps still streak as they slide over. Is this normal? I was kind of expecting them to be crystal clear through all motion.

Thoughts?
 
Probably YMMV. I was playing with in the store, and no other portable device I have ever seen was as smooth. It was actually a bit unreal how smooth the animations were.

However, if you're used to 120Hz+ TVs, possibly it might be underwhelming?

I don't think ProMotion is particularly valuable unless you're doing digital art or intensive photo editing with your iPad. I've been using a 1st gen iPad pro professionally for illustration since it launched due to it exceeding the precision of a typical graphics tablet (I'd been using various wacoms for years prior). I picked up the 2017 model yesterday and the increased specs/ProMotion make the apple pencil dramatically more responsive, and zooming/panning my artwork insanely fluid. Apps like Procreate and Affinity Photo show the potential of what these tablets can do.
 
You are seeing the response time of the LCD. Higher refresh rates don't always mean better response times, and so you will still see blur from the panel.

Just curious, but does OLED have better response times? The text on my S8 looks smooth when scrolling and that doesn't even have 120hz. So if you combine the two (which may be possible if they also include it in the upcoming OLED iPhone), would it be even better/smoother?
 
I personally don't think you need to look for tests

It will either be instantly noticeable and wow effect... or not / unsettling to process depending on person

That's why 60hz is an option in accessibiiity too

Also the real test is going to older iPads to see if you can tell the difference going back and forth

But humans get used to anything, with time. 60hz 120z... 480hz. One day
 
OLED does have better response times. But it also gets a bit tricky. Since both the display and your eye introduce their own blur (and the source can have blur too, in the case of film).

Higher frame rates reduce the effect of eye-induced motion blur.
Faster refresh times reduce the effect of display-induced motion blur.

One issue I personally have with OLED is that lower frame rate content has a different kind of blur than with LED. LED's slower refresh time happens to pair well here, smearing the frames a bit during the transition. It looks a bit like how fast motion is captured by film. OLED on the other hand, doesn't smear the frames, so at least my eyes tend to see it more like two distinct frames overlapped on each other. This effect diminishes as frame rate increases, since it is eye-induced blur.

Of course, if you insert black between frames, you can also attack eye-induced motion blur without having to increase the frame rate, although it doesn't make the motion any smoother, just clearer. CRTs and film projectors do this. Some flat panel TVs also do this.
