iPhone 13 is rumored to have LTPO display, similar to the apple watch.

I don't have any issues with the apple watch with LTPO.

    "As was widely rumored, the display uses mini-LED backlighting with over 10,000 LEDs to deliver true-to-life HDR content."

    It may be a long shot, but I'm interested in seeing if the mini-LED screen is any better in terms of flickering. I'm going to order one and test it during the return period, will definitely post my impressions when it's out.

      Yeah it may be good or 10,000 times worse.

      Just looked at the new line up.
      The new iMacs look nice. I don't think they use mini-led but I'd be curious how the screens go considering their built in.

      Seagull It’s a very well-thought post of yours. However I'm not really sure about the last part of Intel HD not dithering. In my case which is an HP laptop, anytime I go back to the Intel HD driver (from the basic display driver) the colors just totally change, especially white color. Like it is not a solid, static white but becomes a mess of hue, rainbow like colors mixed up to reproduce white, that can not be fixed with any setting. If you tested and saw that Intel HD does not do dithering then it is really strange; is there anything else that it can do differently to the display?

        [deleted] I think it's entirely plausible that the internal laptop LCD connector does something "different" compared to the external display connectors (HDMI, DVI, etc.)

        vince I don’t have any issue with the LTPO display on watch se either

        Has anyone tried the mini led iPad Pro yet? Not expecting it to be different but living in hope...

          FNP7 Someone did end up getting the iPad Pro early, I asked if he would do the standard slo-mo video test and here was his response:

          "I could not get my phone to record a long enough video in slow-motion in order to go through all of the brightness levels. I am one of the few that are sensitive to screen flickering and I haven't noticed anything at any brightness level. The only thing my phone picked up was when I was within the 10 to 15 percent brightness range and lower, horizontal lines appeared, but no flickering. "

          Also, I'm grabbing one on Friday. I'll definitely update with my experience.

          Thanks for sharing the vid, glad someone is talking about the flicker.

          He said:
          "When it comes to flickering, the mini-LED screen is not as flicker-free as the regular LED screen, but compared to OLED, it is much better. And so far, it hasn't triggered my ocular migraine, and I also don't think it will."

          That's not super encouraging, considering that a lot of people get symptoms from other Apple devices with regular LED screens. Glad it works for him though, seems like it's a step forward from OLED at the least.

          TLDR: The miniLED screen is better than OLED on my eyes, but still causes eye strain. I suggest trying it yourself, it's definitely a step forward IMO.

          So I've been using the new iPad since Friday, here are my impressions eye strain wise:

          -Slow motion video of the screen shows very little (If any) flicker, nothing like OLED flicker.
          -It doesn't seem to have that "shimmer" effect that I usually get from Macs.
          -The eye strain from this iPad is much less harmful than Macs/OLED iPhones, it feels like a slight prickling above my eyes after some use, but no migraines (yet)
          -I don't really notice any huge flicker difference between brightness levels.

          I'm very sensitive to flicker, so just because the miniLED screen bothers my eyes doesn't mean you guys shouldn't try it. It's definitely a step up from OLED and the Macs IMO, I think it's worth a shot to try.

          I'm going to try messing around with brightness/white point/night shift/true tone a bit more to see if anything helps, I'll post my results in a few days.

          This is also my belief. I posted about my Philips monitor, that monitor was flickering like crazy in the lagom inversion pattern test. It caused me such a strong eyestrain that i saw real life zig-zag noise pattern at like 30 HZ after using that monitor... It was 100% that monitor causing it(never seen anything like that since im using different monitor, its crazy that they sell garbage like that, it should be illegal to sell products like that monitor), and its either came from inversion or it come from color dithering.

          I had a TN LG monitor, that had very crazy inversion too, i could see the pink/green discoloration thanks to the inversion, it was very strong effect, but that monitor was still easier on my eyes than the ips Philips. I could tell that the image was not stable, but it didnt cause such a hard eyestrain for some reason. Maybe if was obvious for my brain(green and pink pixels flickering), that it didnt try to fight it, unlike with the Philips product where my brain tried to compensate/fight the constant flicker...
          Currently im using a Dell monitor which is ok most of the time, its not flickering in the inversion pattern test. But on dark/gray colors, its instantly triggers some kind of anxiety attack. I think this is maybe because the 6 bit FRC flicker + the very low contrast of the IPS panel that causing it.

          I wrote about my Mac M1 experience in detail here. Today I went to a local Apple store to test new mini-led iPad M1.

          At first I looked at a couple iPads that turned out to be old models. They felt OK to the eyes. Then, the staff showed me to the iPad M1. This works like magic, guys... A MERE GLANCE at this screen triggered my strain. I tried to have a better look at its interface but couldn't last for more than 3-4 minutes. Now, another interesting thing. There was another mini-led iPad with smaller screen. The note said it used A14 chip if I'm not mistaken. And, surprisingly, it felt much better. I still experienced some after-effects after M1 iPad at this moment, though. Should give it another isolated try.

            Nickonomic There are no mini-led ipads except for the 12.9" pro. The smaller screen model you were looking at wasn't the mini-led version.

              Sunspark Oh, thx. It was iPad Air and it said Liquid Retina smth -- I thought it was their marketing name for the new mini-led screens.

              We just need to accept that Apple is mostly a non-starter and has been for years.

              Not disagreeing with you there, just posting the latest info for others sake.
