    Does anyone else notice a slight ghosting effect / lag while scrolling on the iPhone X? I’m not sure if I have a bad panel but when I scroll through text (e.g. the settings window or in Safari) even at a moderate speed the text is blurred. Compared to my iPhone 6S it’s pretty bad.

    Has anyone else noticed this? Does it work well on some and not others?

    Noticed here too, but isn’t this just the difference of the OLED screen from the LED one we’re all used to?

    I don’t know. Is this common with OLED screens? I have friends with OLED TVs that don’t exhibit noticeable ghosting / blur with action or fast moving text. In fact, everything seems super crisp and sharp. I didn’t know it was an issue with OLED screens in general.

    Do all other smartphones with OLED have this? Are some panels worse than others?

    That effect is from the OLED. And it is so quick, it is barely noticeable.

    I suppose "quick" is subjective. It's definitely noticeable to me. Typically I'm able to scroll past text and easily pick out words but I can't really do that with this phone because things are a bit blurry. If this is common for OLEDs then they're not superior to LED. In fact, I can't really tell the difference in colors or contrast from my iPhone X and my 6S... but that's not the topic of this thread.

    I'm pretty disappointed if this is what to expect from all iPhone Xs \ OLED panels.

    Text isn't blurry for me although I do notice a very fast slight wave in the text as I scroll fast.

    Hmm, that's interesting because a friend of mine also claims he doesn't see any blurry text while scrolling so maybe I have a bad panel. I'm going to drop into an Apple store today and compare against the store phones.

    Good idea. Better to know early on if there is a problem.

    Yeah, I was hoping that others would chime in too and say whether they face this or not.

    I am also having this issue. This is especially noticeable when the brightness is set low at night (almost a jaggy action/not as smooth when text is scrolling). It is improved when the brightness is turned up, but is still faintly noticeable. I went to a local Target and Best Buy and confirmed that their demo units also had the same issue. I am wondering if this is an issue inherent to the OLED screen that Apple is now using. Please keep us posted when you go to the Apple Store to compare units. Thanks!

    I have this same issue. It’s like a bright blue glitch type effect for me. Most noticeable when I have nightshift on and brightness down low. Really dreading a Genius Bar visit and dealing with a replacement but not sure if this is normal or not?

    I thought my X had more ghosting than my 7, so I fired up the 7. They were pretty much exactly the same, except that the 7 looked more like motion blur and the X looked sharper and more like ghosting. But they were both distorting scrolling text by the same amount. The 7 looked more pleasant because motion blur is nicer looking, but the X was easier to read in motion.

    Think we’re seeing how IPS vs OLED handle the 60hz refresh rate. Both are 60hz, the blurs just look different.

    Tested out my partner’s X yesterday and this was the first thing I noticed. I have an S8 that I play around with which exhibits very similar behaviour. I’ll chalk it up to being inherent to the display technology.

    Also, I believe the touch response is actually 120hz, so the phone is actually snappier than the screen can display.

    We’re going to see a 120hz screen at some point in the future and it’s going to be that next big Retina display moment that improves the whole experience. But that will also put twice the strain on the GPU and eat battery life, which is why it still hasn’t happened.

    Hey AngelGuy7, were you able to drop by an Apple store to compare vs their demo units? If you haven’t, If you go would you mind looking at the issue with the phone brightness turned way low? Thanks!

    The colors isn’t as good in the OLED... the blacks is a different story tho.

    I noticed this too when scrolling, looks like a screen with a low refresh rate. Don’t even try to compare it to an iPad Pro with ProMotion.......

    At low brightness? Do we know if the panel is using pulse width modulation for controlling the brightness? PWM can cause artifacts (ghosting/blur) that are more visible or only visible at low brightness levels. PWM also cause eye strain and even triggers headaches in some people. Basically, the screen controls brightness by flickering on and off at high frequency. You don’t SEE it, but it still messes with some people. Apple isn’t using PWM in their LCD displays to my knowledge anymore. You can sometimes see PWM by recording the screen with a camera that can record at high FPS. You’re more likely to catch it at low brightness levels because that lowers the on-off frequency. The display will flicker in the recording or show light and dark bands that move across the screen (or sometimes static if you hit the right frequency).

    Hmm, according to this Reddit post the iPhone X does use PWM. Apparently Samsung OLED screens do.

    I’ve also had this blue glitch issue when scrolling with low brightness and nightshift. Raised it with support as I couldn’t replicate the issue on a friends X. They’ve taken a capture data and passed to engineering - hopefully will hear back tomorrow, but have a feeling it’s going to be a replacement device :/

    I’m not sure. If it’s not happening to all devices, then it’s likely hardware. OLED is a new technology to Apple so support couldn’t confidently say whether this was an actual issue or expected with OLED.
