I would bet most people would fail a blind test.

Basically everyone who has played videogames on pc will notice the difference. I easily notice a drop from 360Hz to 240Hz.

I also use 60Hz screens just fine, saying that getting used to 120Hz ruins slower displays is being dramatic. You can readjust to 60Hz again within 5 minutes. But I can still instantly tell which is higher refresh rate, at least up to 360Hz.

Videogames also do the input every loop so there's a big difference there. It must be evaluated with a video only.

We're talking about monitors here, which usually have a mouse cursor on it for input. Of course it would be hard to tell between 60 vs 120Hz screens if you used both to play a 30FPS video.

Lots of games don't do input on every loop. Starcraft 2 has 24 hz input.

60 to 120? Generally there are tell tale signs. If I quickly drag a window around it’s clear as day at 120.

Most people who’ve used both 60 and 120 could tell, definitely if a game is running. Unless you’re asking me to distinguish between like 110 and 120, but that’s like asking someone to distinguish between roughly 30 and 32.

North of 120 it gets trickier to notice no matter what IMO.

I can live with 60 but 85+ is where I’m happy.
