Since stroboscopic effect was mentioned, I thought I'd add this article.
Using a higher refresh rate (and get rid of PWM/flicker) is the only way to make the stroboscopic effect less apparent and to reduce motion blur (a big culprit which a lot of people here do not discuss enough here), the same way you alleviate PWM dimming / multi-strobe flicker issues (if not accounting for the good kind, single strobe, which doesn't work for some people either)
I'm very sure there are more people which have eyestrain issues due to motion performance issues (LCD artifacts, slow response times on OLED displays due to 'burn-in' algorithm, low refresh rate, PWM flicker causing 'stutter-like' motion, potential VRR flicker due to bad implementations of variable refresh rate which are also a thing on desktop monitors) and calibration issues (bad gamma, color temp being way off / too cool for some, font rendering, pixel layout, irregular SPD graph) than due to dithering.
There are a ton of outside factors at play as well and one cannot pinpoint the culprit without ironing out all potential causes.
A matter of trial and error sadly, considering how undocumented smartphone display reviews are in the western part of the world. (even Russians don't seem to test fully , just compare monitor display reviews compared to smartphone ones)
Smartphone display reviews should be approched the same way as desktop monitor displays are approached.
Finding a properly calibrated LCD smartphone display with fast response times is extremely challenging sadly, as most people testing this lack the equipment. Not even gonna go into the lack of the 3.5mm jack, microSD slot, removable battery and software quirks devices can have.
I'm very surprised that display manifacturers aren't making VA LCD displays for smartphones. They could easily do >3000:1 contrast ratio and VA can definitely be fast enough to not have black trailing on 120hz. Would make for the perfect technology till OLED's successor, microLED releases (probably not in this decade sadly :/)
1440p 240hz VA <6.5" phones, when? D:
Oh, and a plea to people which mention that software updates give them headaches.
Can anyone of you get any colorimeter devices with which you could verify your findings? I just find it hard to believe a single software update can ruin a display for some individuals. Very interested what the culprit is behind the scenes.
