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
It’s harder to notice the difference at first. When I first got my 144Hz monitor I had trouble distinguishing between the two, but now I can immediately tell (and it’s made going back to gaming at 60fps really difficult lol).
If you keep using 120Hz mode, then after a while you’ll definitely feel the difference between the two.
That said unless you game on your phone a lot, I don’t know how useful it is to have it set to 120, especially if it drains more battery.
Even moving windows around looks and feels stuttery on desktop at 60hz, which is a pretty simple action. Basic desktop navigation I find more bothersome than 60 fps in a video game, since the system just feels and looks less responsive when it comes to animations and scrolling and moving stuff around.
I had to replace my old monitor that was 60 hz that I was intended to use as my secondary, since it was way too jarring having the two side by side. I avoided using the second one because of how suddenly it felt laggy entering that domain. Just the cursor movement looked bad.
