Nah, you’re not the only one. 120Hz is a lot like 196kHz sampling rates. 120Hz is good for some things, especially professional video work (kinda like how 196kHz is good for studio audio work but makes no difference to sound quality), but you lose the benefits of it in almost everything else. 60Hz tends to be a perfectly fine refresh rate for most activities (though I did prefer 75Hz back in the days of CRT, as CRT had a bit of a flicker at 60Hz that was gone at 75Hz), and most people probably can’t sense more than 60Hz to 80Hz. But, like with studio audio work, when you’re doing professional work, it’s always easier to work with more data and render it down to 60fps (or 30, even) or to 44.1kHz for publishing than to try to master at the same specs that you’ll publish at. It’s always easier to have extra data that you can throw away instead of trying to extrapolate and interpolate data that isn’t there. I kinda wonder how the audio industry did it back in the early CD days, when 14 bit quantization and 44.1kHz was the max sampling rate, before DAT introduced 48kHz 24-bit audio to recording studios and before even 16-bit quantization came down in price for the pro market.
