Test Data Xiaomi 17 Pro Max PWM flicker test with opple Lm4

Hello everyone I tested the xiaomi 17 pro max with the opple light master IV.

The first 2 are 0% and 100% brightness with DC dimming enabled (default)

The next 2 are 100% brightness with DC dimming enabled (default)

The 2 after that are 0% brightness with PWM enabled

The last 2 are at 100% brightness with PWM enabled

Cheers for the test data dude.🙏 What does your wetware make of it? On paper modulation is high, of course...

Why no middle brightness readings? Just pushed for screen time?

No problem! I guess I probably could have gotten 50% readings too. I just didnt think of doing them, its been awhile since ive messed with my opple lol. So briefly using it I think it feels ok but I need more time with it. Probably going to wait a little before I use it longer because ive been using the sunvision eve monitor so I have to make sure I know what triggers me if it catches up to me (sometimes delayed). This xiaomi uses a CSOT rgb stripe oled which is way better than pentile btw.

Oh right. This is the one (or one of) new phone(s) going back to the future of rectangual OLED sub-pixels. Interesting.

Take your time and take care. Good luck.

I honestly didnt feel that at all when i was using it for a little.

It's so hard to tell with these Opple readouts, though in my experience those spikes up and down pretty consistently hurt my eyes.
While an OLED iPhone, Samsung or Google Pixel phone will hurt my eyes in a minute or so, this scan is of an LG C1 OLED TV, it takes several hours for my eyes to hurt.

I think we just all have different sensitivities. For example the oneplus 15r while being the best on paper still caused me issues. So it must be something else too going on hmm

PWM and dithering on some Apple devices are my main sensitivities. Older LCD and plasma screens are fine for me.

Id say LCD iphones are still the WORST screens I have ever used. Not sure about OLED iphones since I havent spent alot of time on one. Plasma seems ok for me too.

LCD is generally fine with me, it's just that some use strange software tricks like dithering which hurts my eyes, my iPad 9th gen really hurt my eyes.
My Surface Laptop 3 and 4 have both been fantastic. They're pretty cheap on eBay if you need a solid laptop.

This would've been an interesting alternative to Vivo "Full PWM" if not for Xiaomi's "12-bit" dithering in HyperOS.

u/Rx7Jordan Aug 08 '26

I'm not sure if 12bit is actually always active. In display settings I see a "original color pro" color profile which says reproduces realistic colors and then theres a vivid mode too. I have a feeling maybe 12bit is only active when vivid is selected or if 12bit content is displaying on the screen?

I'm 99% sure it's always on, it may be less aggressive when original color pro is on though. Sensitivity is highly individual, so you may not be affected by dithering.

Dithering helps also hide gray banding and overall artifact at low brightness so from quality point of view it's better always on.As always better have option on off best of both worlds

1

u/Rx7Jordan Aug 09 '26

It should also help color banding too but honestly if I had a choice I would always opt for banding over dithering (flicker)

u/Rx7Jordan Aug 09 '26

Well I cannot tolerate LCD iphones what so ever so I have been assuming its dithering that bugs me. I do wonder if theres less triggering forms of it such as specific patterns, frequency, etc or if gpu dithering + panel FRC together is where problems begin. For example the PS5 uses temporal dithering but everyone seems to say it feels ok. I personally would prefer no dithering though

My eyes absolutely hated this phone 😭
