I doubt that the upcoming update of the 24-inch iMac (expected this year with an M4 processor) will offer a display with 120Hz, but if Apple upgraded it to 75Hz that would be nice.
And it would help make the all-in-one a better gaming computer. The current 24-inch iMac has a 60Hz display. But, as Tech Guided notes, the difference between a 75Hz and 60Hz monitor is more noticeable than you might initially think, meaning 75Hz should be opted for over 60Hz whenever possible.
From the article: Monitors with a 75Hz refresh rate are quickly becoming just as common and inexpensive as 60Hz ones, so price is becoming less and less of a reason to opt for 60Hz over 75Hz. And, for this, you’re getting a monitor that feels noticeably smoother than a 60Hz one, making it a solid go-to option for budget, non-competitive, or high resolution gamers. 75Hz is even a formidable refresh rate for the more casual end of competitive gaming—pro gamers are unlikely to game at 75Hz, but casual gamers can play competitive games at this refresh rate without suffering too great a disadvantage.
That said, if the next gen 24-inch iMac “only” has a 60Hz display, it would still be a decent-if-not-great computer for gaming. Again from the Tech Guided article: Even though higher refresh rates should provide a better gaming experience than 60Hz in all use cases, 60Hz is still good for gaming. It should be reiterated: a game running at 60fps on a 60Hz monitor still gives just as smooth of a gaming experience as gamers have had for years before the shift to higher refresh rates.
In many games, in fact, the difference between 60Hz and a higher refresh rate like 120Hz or 144Hz isn’t very noticeable. For example, if you tend to play 3rd person games with a controller, sitting a little away
