Can read the content clearly while smoothly 120 Hz scrolling or moving windows around.

How often do you read text while moving the window containing it around? Does that justify the 2000$ expense for a 4K 120Hz monitor?

Personally, I find this 120 Hz endeavour pretty pointless when most applications have input lag that's way worse than a single 60 Hz frame.

You can do that just fine at 60 Hz, if there is no tearing (all screen updates appear during vertical sync).

You can read scrolling movie credits just fine at 24 FPS.

>You can read scrolling movie credits just fine at 24 FPS Honestly I actually struggle with that. But working and gaming at 60hz is still perfectly fine with me. I even purposely run my Valve Index VR headset at 90hz instead of 120hz because I don't need the extra frames

What do you mean you "don't need them"? The jump from 90hz to 120hz is huge. The jump from 60hz to 144hz is life changing.

Guess I never thought about that. Is the difference noticable. I always thought High refresh rate was for gaming.

High refresh rate has to do with reaction times in competitive multi-player gaming.

You absolutely don't need 120 Hz in any single player video game produced between 1978 and 2020.

Games at 15 FPS (even less) used to be perfectly playable and fun. At 30 FPS things are smooth well past giving a damn.

15 fps was never perfectly playable.

You can't play a game at 15 FPS. It's a moving slideshow. And it was never fun. 30 fps looks pretty bad, and even 60 fps is decently choppy. I'm not sure what your exact point is, but once you try 144hz or higher, you'll never, ever, go back.

Who is reading content while scrolling? That's like buying a $10,000 stabilization unit to be able to read a book while jogging.

It's very common on smartphone/tablet. Less common but also on PC.
