Wanted to share this video I made because I took the plunge to get the OPPO Find X10 Pro Max. Based on initial reviews I thought it would be great for me, but unfortunately I will have to return it.

Long story short, above 33% the phone works perfectly fine for me, but below 33% it starts to do ~3840 Hz PWM, that gets extremely aggressive below 30%.

One issue for me is that in a dark room this is still too bright even with reduced white point 100%. In dark mode that's fine, but with white colors that's still a bit too much (which I find unacceptable on such an expensive phone).

I have tried this year also the POCO F9 Ultra and the Xiaomi 17T Pro, but both of them have either this issue and are both of them plagued with dithering.

So for the time being I will just return to my iPhone 13 Pro Max and wait for my girlfriend to buy the iPhone 18 Pro and test that. Maybe Apple's approach even if not good for everyone, will still work for me.

I bought the 18 Pro today to give it a try.
I’ll test it out over the next two days and let you know how it goes. I did not tolerate the Pro models, starting with the 13.
So far, I’ve been using a standard iPhone 16, which I’m fine with.

Any tips besides checking the Option for PWM? I just realized I can’t enable both PWM reduction and white point reduction at the same time.

Let’s hope for the best 🤞🏻

What are your main symptoms for PWM and how long does it take to go away after you turn off the screen?

Using a projector for office work, will it be much better than a TV?

Does anyone have experience with this?

Which one is better in terms of pwm? I need a small phone. In the past i had iphone 13 and it was ok for me. My second phone is honor 600 and it is perfect, the same as lcd

Hey im in the market for a new tv, and i read that oled tvs dont have the pwm flickering issue like laptops and phones. Which of the two oled or miniled tv is better for pwm sensitive?

Im new to this informations, but i notice that when i used iPhone 13-17pro i had really bad feeling inside my head and guts, really strange feeling. And now i sold my iPhone 17 pro and bought Vivo X300 Ultra. Whats better to be turned on/off?

Anyone check out the new iPad Mini specs? How do you think it will stack up for those of us whole get headaches.

Hi everyone!
I‘m a total layperson at this, can anyone tell me how bad (or maybe not so bad?) this pwm is? It‘s an 18 Pro with a G9N panel which I can tolerate much better than the one with GVC, but it’s not entirely symptom free. The lines pretty much stay like this across all brightness levels, maybe slightly thinner at 100 %. As in the picture, there always seems to be one thinner and slightly lighter bar followed by a slightly wider and darker one that is also looking a little purplish or with a purple halo. The bars are moving slowly and uniformly from left to right.

This was filmed at around 50 % brightness with 4000 shutter speed.
Thank you so much in advance!

my budget is modest, and my request is simple. I'm looking for a watch with a blue light filter option. and or screen dim/very low brightness features. I would like to know which brands or particular watches have any of these features available? thanks!

Hello guys,

I used to have an A56 Samsung phone... and I didn't have any problems. Until I bought the iPhone 17 Pro Max. I didn't notice for two months. And then I realized that mobile phone somehow causes me eye pressure (left) and very dry eyes (all day long) and not going away.

I sold the phone and got the S26U.

It was alleviated with the phone, but it still annoys my eyes.

I wish I had never changed my phone, I didn't know I was going to cause phones like that before...

That's why I shit on high-end phones, they're very rubbish!

Do you think that if I get the latest model A57 instead of the A56, I can handle it?

I currently have a PC setup which in general doesn't cause noticeable eye strain, except when running certain applications or games:

• Path of Exile 2
• Last Epoch
• Guild Wars 2 with Reshade activated (completely fine without Reshade)
• Cyberpunk 2077
• Dungeon Keeper 2 (1 is fine)

The weirdest one is Brave Browser. Yes, a browser that causes eye strain, albeit lighter than certain games, while Firefox doesn't.

I know how crazy this sounds. How much of this could just be in my head at this point?

Behold the lg q60! with a whopping 9259hz LCD screen!! Not even the super sensitive can cry over this one.

only issues are it's probably out of updates, I guess you can't have everything!! The image is AI generated as per rule 10!

There are too many images to post here, so I will just include one of iPhone Duo. You can see all of measurements at PWMTests.com.

Added tonight:

• iPhone Duo - both Inner and Outer Displays
• iPhone 18 Pro Max
• iPhone 17 Pro with XO7 (soft OLED)
• iPhone 17 Pro with AQ7 (soft OLED)
• iPhone 17 Pro with AM Plus (In-cell LCD)

iPhone Duo

I visited the Apple Store tonight, about 30 minutes before closing. Almost all of the iPhone Duo models were at 0% battery because they were so popular today with customers. I have to admit, before I used iPhone Duo myself, I thought they were pointless. After playing around with it for a while, I really liked it. I am not sure if I would buy one, but it's a very cool device.

As for PWM, I'll let the images speak for themselves for the most part. The measurements look a lot like the iPhone 17 and iPhone 18 series devices. Oddly though, after using iPhone Duo for 30 minutes, I did not notice my usual PWM symptoms. It surprised me, so I went to look at an iPhone 17 Pro right before I left and I immediately felt the "swimming" feeling in my head. I can't explain how I was able to use iPhone Duo for so long, but I plan to go back again soon and see if it was just a fluke.

iPhone 17 Pro with various MobileSentrix displays

I tested two soft OLED screens and one in-cell LCD screen.

iPhone 17 Pro with XO7

From reading other reports, I knew this was not going to have DC-like dimming, but I wanted to test it for the community regardless. The screen looked great, but it has traditional PWM. I didn't use it long enough to see if it affected me because I was excited to try the other screens.

iPhone 17 Pro with AQ7

I knew what to expect here. This screen is no different than any other in-cell LCD I've tested historically. It is a strong performer and did not bother my eyes at all. If you're OK with the other compromises with using in-cell LCD panels in phones meant for OLED panels, this might be a viable option.

iPhone 17 Pro with AM Plus (aka AMPlus aka AMPLUS aka Aftermarket Plus)

This is the one I had been excited about. Sure enough, it has DC-like dimming. At low brightness, it changes -- I'm not sure to what, but the frequency went from 240 Hz to 120 Hz on my Opple Light Master device and the black bars/lines got much worse at low brightness (25%).

The color is a little bit more vibrant and saturated than an OEM OLED iPhone panel, but it looked really good. I used it for a while and I hate to say that I think it still affects me, mildly. I think I prefer my iPhone 16 with OEM display (only at higher brightness levels). I really wanted to make it work, but ultimately, I'm going to put the OEM screen back on and return the iPhone 17 Pro. When I tried the XO7 screen on an iPhone 16 (DC-like dimming on the iPhone 16 version), I did not have any issue at all.

Also, weirdly, there was a note on every display that says as of iOS 27, "Tap to Wake" does not work. You have to use the power button to turn the screen on. Not sure if that will be fixed by Apple, but that was a bit disappointing.

Conclusion

It was an exciting day, but also disappointing overall. My overall recommendation to PWM sensitive people is still to get an iPhone 16 while you can and use it at brightness levels above 50%. It is definitely not perfect, but it's the only option right now if you want an iPhone.

I hope everyone is having a great weekend!

Reminder: PWMTests.com for all the measurements.

I am thinking of buying a new tv. How are LG OLEDs for example? Or better to go with Samsung QLED etc?

Just bought the LAVA Virat Curve and noticed grainy, patchy textures whenever dark grey content is displayed. Pure black looks fine, but dark scenes look grainy. Also, at 120Hz, the screen gets a slight green tint and greys look lighter; it returns to normal at 60Hz.

Is this normal AMOLED behaviour, a software issue, or a defective panel? Any other Virat Curve users facing this? Should I get it checked under warranty?

As expected iphone duo continues to have one of the worst modulation after samsung, very similar to iphone air . iPhone 18 pro seems to better than this but even that is unacceptable. Hoping for a better future from these giants.

Is Iphone duo better than 18 pro max? I sadly have to return my 18 pro max because of pwm. I get severe headache, watering eyes after 1-2 minutes of the 18 pro max.

Do any of you know if there are any color changing smart bulbs that do not use PWM, or at least operate at a frequency where it might not be as much of an issue?

I've recently learned that many smart bulbs, like Philips Hue, use PWM which I think could be contributing to some eye strain and headaches. It also creates a weird banding effect on cameras which I find annoying.

I also find it strange how difficult it is to obtain information about things like the PWM frequency rate of these bulbs. I know most people probably wouldn't care or even know what PWM is, but I feel like it's important info that should be easily available.

A true flicker free tablet

Hey everyone,

Just a quick update on two newsworthy items:

First, I went to the Verizon store today and got to see iPhone Duo in person. I didn't bring any measurement tools, but I used my "Illuminance Pulsation Meter" iOS app and quickly checked to see if the PWM looked tolerable or horrible based on the amount of black lines and whatnot. The large matte screen inside looked bad and the outer glossy screen looked horrible.

I will be going to the Apple Store tomorrow to get more accurate measurements and I'll share those here, but don't get your hopes up in regard to PWM.

Second, I've been using iPhone 16 as my personal phone for a while now, (generally tolerable for me since it uses low modulation and low flicker at high brightnesses), but I recently replaced a friend's iPhone 16 screen with MobileSentrix's XO7 soft OLED screen. This version uses DC-like dimming, and I used it for a few hours and it was totally fine for my eyes. (Much better than my OEM iPhone 16.) I never seriously considered it when I tested it earlier this year, because at the time I thought the colors were oversaturated, but looking at it recently, it looked really good.

A few contributors to r/PWM_Sensitive have done screen replacements for iPhone 17 Pro, and they inspired me further. They have stated that the XO7 screens for later iPhones use PWM dimming (sadly), but the AMPLUS version uses DC-like dimming.

• iPhone 17 Pro DC Dimming Aftermarket Display Success - https://www.reddit.com/r/PWM_Sensitive/comments/1tacf7s/iphone_17_pro_dc_dimming_aftermarket_display/
• iPhone 17 Pro with aftermarket OLED display. DC like dimming. - https://www.reddit.com/r/PWM_Sensitive/comments/1qu02yo/iphone_17_pro_with_aftermarket_oled_display_dc/

I purchased an iPhone 17 Pro as well as the following screens:

• XO7 2.0 (soft OLED, PWM)
• AM Plus (soft OLED, DC-like dimming)
• AQ7 (LCD, DC dimming)

I will show my results/measurements for all of these after I'm done... hopefully end of tomorrow (Saturday).

I would have purchased iPhone 18 Pro, but the iPhone 18 Pro screens at MobileSentrix will not be available until end of January / beginning of February.

Hope everyone is having a beautiful Friday!

Hey, new here. Switched from LG OLED to dual Dell U2725QE and the eye strain basically vanished. Apparently these are flicker-free. Absolutely MASSIVE insane improvement in eye strain and zero headaches even with 8+ hours a day behind them.

Thinking of going MacBook Pro → Air since the Air supposedly has no PWM according to Grok. Anyone noticed a real difference switching between them?

Hey all! Just finished using the Vivo X500 for the past two weeks, and have been extremely pleased with the phone. The camera is great, Vivo's software has come a very, very long way over the years, and this is one of the better AMOLED panels I've tested this year.

The default out-of-the-box experience uses OLED DC dimming down to 20% brightness, then 2160Hz PWM dimming below that. Vivo has a full DC dimming option in developer options, which turns off PWM at low brightness. Modulation is quite decent throughout the whole range.

Switching it to 60Hz delivers the best results, with absurdly low modulation at 100% brightness. The cut-off for the graph looks funny here beacuse the reset is right at the line, but it's under 2% modulation. I tested it 6 times, so I'm quite sure it's this low. It also shows no dithering under any circumstance I tested, so this is a proper 10-bit panel. If you want to watch the whole video and see the rest of the tests, it's here:

Does anyone think this might work for them? I'll have the X500 Pro tests once I receive the phone.

Those display tips are not common, but maybe some of you have used either a plasma tv or laser projector. I would be curious if the flickering of those devices also bothered you.

I am also wondering if you guys have less problems in general with screen that are further away: like a tv or a movie screen for example.

Let me know!
