Re: Strobed Motion Blur Reduction Is Same As PWM (but good kind of PWM)

I have a question about this (please feel free to delete or move if appropriate).
The new iPhone 14 is measured by some reviewers as having a 60Hz PWM rate with a 60Hz refresh rate. When those reviews were published, PWM sensitive users were furious that Apple went with such a low PWM refresh rate.
If I understand this correctly, this should actually be much better for PWM sensitive users as opposed to the non-synced rates of previous iPhones.
Interesting! The decision of framerate=Hz PWM is a tough decision, which is a pick-poison between PWM flicker and motion blur. Some people are more sensitive to motion blur, and some people are more sensitive to PWM.
Alternatively, it might be a confusion with the OLED brief black flicker (less than 5% refreshtime), which has no discernable effect in motionblur.
Are you able to tell me if there's some motion blur benchmarks with the iPhone 14? I have not been paying attention to iPhone 14's motion blur performance at various brightness settings, although I have been itching to buy an iPhone 14 Plus later this year.

The two best, which appear lacking, are probably these two:

Thank you!
I guess I will find out when I get an iPhone 14 Plus later this year to upgrade my old phone.
