Just got a new phone (OnePlus Nord 3), turned refresh rate HUD in developer settings and I see some parts of the system and some apps display 120 Hz but I have problem noticing any difference, same with my wife’s Redmi Note 12, i have to look very carefully and maaaybe I notice some different, not sure
I find that I’m always perfectly happy with my current monitor or phone screen, until I see something better. Ignorance is bliss. For this reason, I deliberately try to never see any better screens, this way I always seem to remain endlessly impressed by my 75 quid Philips 1080p panel!
