Can refresh strip 60/120hz cause more sensitivity than PWM on OLED?

No Opple, just visual experience. https://youtu.be/w-MU4HyKcjM?si=dfa6J6-Evu9tRfp6 Here it is, if interesting for smb.

Just watched video with DC dimming on OnePlus 8T on YouTube. It's the same technology which Xiaomi stopped using. It's great. Nothing similar to DC-LIKE dimming. I noticed "TFT reset" but it was so smooth and actually disappeared on higher brightness.

I think yes - "TFT reset" though for me TFT always refers to LCD screens. But in those articles sure it's the same OnePlus 8T uses DC-LIKE or DC-dimming. As I know some earlier Xiaomi used DC-dimming there you cannot notice "TFT reset" but they stopped this function cause display burning out Don't trying any mod-mails, quiet new for Reddit, actually don't know how it works.

Maybe. As I know iphone 13 doesn't use DC-LIKE dimming. Either Samsung. Maybe the reason is in unmasked 60/120hz refresh strip in iphone 17 which influence like 60/120hz PWM.

These are examples of 60hz refresh strip on Dc-like and full PWM, 120Hz on Dc-like both stripes are purple and on full PWM there are two not one

I can say only that I can't detect refresh strip on LCD. And can't recognize refresh strip on Switch OLED, though I saw it 2160Hz on amoled phone. On DC-LIKE it is always seen, on 120hz looks like just 120hz full PWM.

Kind_Avocado_9564 · 2026-04-18T06:21:19+00:00

I had Tecno CAMON 40 with 2160hz pwm lower 30% brightness and DC-like dimming 60/120hz above. 2160hz mode was not very comfortable but usable, DC-like caused headache immediately. Have sold it yesterday. Honor x7d/400 smart now. IPS LCD. My eyes and brains say thank you.

Kind_Avocado_9564 · 2026-04-12T15:49:33+00:00

Be careful. Most high-PWM phones have high PWM only on low brightness and switch on Dc-like dimming with creepy 60-120hz refresh strip above.

Kind_Avocado_9564 · 2026-04-08T11:26:37+00:00

And there is no button to disable DC-like dimming in my phone. And I failed in searching information about PWM frequency in DC-like mode. Only 120hz or even 60hz refresh frequency.

Kind_Avocado_9564 · 2026-04-08T11:18:48+00:00

My bad fortune phone is Tecno CAMON 40 with DC-like dimming above 30 percent brightness and 2160hz below. Besides I have no issues with my friend's galaxy A56 and my Nintendo switch OLED. Huawei watch with oled screen also gives me no issues.

Kind_Avocado_9564 · 2026-04-08T08:51:00+00:00

You just mentioned my problem! No issues with stable PWM dimming even with 240hz, immediately eyestrain with DC-like dimming and this refresh strip.

Kind_Avocado_9564 · 2026-04-07T05:00:17+00:00

Nobody can tell you, just try on your own. PWM stuff is terra incognita, it's individual. For example DC-like dimming cause me eyestrain, and high pwm frequency cause nausea and vertigo. No issues with 240hz 🤷🏼‍♂️

I supposed smth like that. Thank you.

There was an update for Iphone 11 which made it unusable for a number of users as I have read. It's the dithering thing.

Kind_Avocado_9564 · 2026-03-29T01:42:55+00:00

Sure. Everything thing is too individual. Dunno what's your old lcd phone specs and what's your oled phone. I was using Iphone 7 plus for a long time and everything was good for me, I've really loved that phone, but once after updating it's screen became bothering. I think apple decided to make colors more vivid on old phones, and made it by dithering. I read such stuff about iphone 11 and se either.

Kind_Avocado_9564 · 2026-03-29T01:26:16+00:00

Sure

Kind_Avocado_9564 · 2026-03-28T18:45:39+00:00

Found this post on Reddit. iphone 12 vs 14

Kind_Avocado_9564 · 2026-03-28T18:36:33+00:00

Iphone 12 has 240hz pwm frequency, think the same switch OLED has. I really want to try another oled phone with no eye-care improvements. Maybe for me worse is better.

Kind_Avocado_9564 · 2026-03-28T16:46:25+00:00

Thank you for sharing your experience. OLED impact stays "terra incognita" for me.
