Just wondering how many people here find that scrolling on the OLED displays on the X and XS/XS Max appears to exhibit significant stutter? And if so, does it bother you/have you gotten used to it?

I have had my XS for about a week. I love the phone except for this. I find that scrolling at medium-slow to relatively fast speeds in any app exhibits significant stutter. On darker backgrounds especially I also notice red/blue/green trails on the screen as I'm scrolling (most noticeable on the borders of images and videos). It's almost as if the refresh rate of the display drops while scrolling.

From what I've gathered, this is actually normal for OLED screens and is because they have a faster pixel response time than LCD, resulting in less motion blur (which in turn results in the perception of a less smooth scroll). Searching the forums and Google has returned a dozen or so results were people have mentioned this in regards to the iPhone's OLED display.

While I do not believe there is anything wrong with the display on my XS, I have not yet been able to get used to the stutter. It tends to make me feel a bit dizzy and also results in my eyes feeling tired. I have noticed that upon waking up in the morning, or under certain lighting conditions I do not notice the stuttering as much (oddly it also will often seem less noticeable with the phone out of it's case).

I'm curious just how many people notice this, and if you'll eventually get used to it. This is my first experience with an OLED display so I have nothing to compare it too besides several years of using LCD screens. Could it be possible that this is actually in part a software or hardware issue?

Thanks.

There are already 2 topics with shutter and flicker. Yes it happens on mines too.

I noticed the same effect and I find it extremely distracting on some of the content with big differences between light and dark areas. As you mentioned it causes some discomfort and combined with PWM I have some serious eye strain even after short use.

I think the effect would matter less if the display had 120 fps panel or if software could somehow simulate motion blur when scrolling text to make it look more natural.

Agreed. I wish Apple would at least add the option to simulate LCD motion blur.

I find it surprising that most people are not able to perceive it, which means Apple will probably not attempt to address it. I must admit, I was a bit surprised that the XS did not have a 120Hz refresh rate. Seems like an obvious thing to include with an "S" upgrade considering the iPads have had it for over a year. That being said, maybe the OLED technology is not yet there to create a good 120Hz panel.

Every OLED iPhone screen will have this. It’s part of the display technology. It’s not stutter or lag. Personally I think it’s the biggest drawback of OLED, but oh well.

The ProMotion LCD display on iPad Pro is so beautiful in comparison.

I do not have this issue on my X but I do have this issue on my XS and another replacement XS after returning the last one.

Clearly not every OLED screen will have this as the iPhone X is as smooth as butter when it comes to scrolling.

It's not only during scrolling, with my XS (bought yesterday) there is a very noticeable drop in frame-rate when closing apps. It happens only if you open an app and leave it idle for 10 seconds. If you close it after that time, you can notice.

Also games, even not graphically intensive games like Hearthstone, have frame-rate drops. Very disappointed, as my 7 Plus was butter-smooth on iOS12.

I've activated the reduce motion feature and now it's butter smooth, but of course this is not a fix......

I’ve had reduce touch on since 2013. As I dislike animations and eye-candy. Maybe that’s why I don’t see many if these issues.o_O

Since creating this thread I’ve had a chance to play around with some of the display models at an Apple store and noticed that they all exhibit this stutter — even the XR seems to as well to some degree. I think it’s normal and just something some people notice and others don’t. I don’t really notice it anymore.

Have you tried watching a movie with 24 FPS on the OLED?
It’s a horrible experience. That jitter/lag is so prominent...unwatchable.

I find it one of several disadvantages of OLED, but it doesn't seem to bother many.

What’s an example of such a movie on what service?
Any service. 95 percent of movies and tv shows run at 24 FPS. Different Services might not give you a native 24 FPS, SkyGo for example feels slightly smoother, they might stream in 30 FPS?!
Netflix and iTunes play native 24.
Somehow Netflix gives you a slight worse experience than iTunes, especially if you watch HDR.
Best to test: Lost in Space S1E1 on Netflix, 38 min left, scene when dad and son walk through the snow.
Generally very bright scenes are worse than dark scenes.
Interesting, when you search Netflix for HFR (high frame rate) the show The Haunting of Hill House appears. Feels somewhat smoother. Can’t tell though if the show gives you more than 24 FPS. One may also just perceive it differently because the show consists of only dark scenery.

Saw this episode previously on my max. I didn't have an issue or thought it was anywhere close to unwatchable. So maybe I'm not as sensitive to the artifacts as other people, or I just don't care. Haven't searched or watched HDR content on netflix. In general what I watch from netflix on my max I don't find issues with the image.

Take back the comment about Haunting of Hill house. When searching for HFR, I get different results every time.

But type in: high frame rate and watch the clip SPARKS if you want to know what real 60 FPS look like!

That’s great. Wish I wasn’t so sensitive to these sort of things.

I noticed this when I switched from 7 plus to X. After using the X for a year I no longer notice it
