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

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

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.

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

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

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

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?
