Would 90Hz work with the older Thunderbolt 4 devices? Can't really think of any other reason they would go for 90 over 120Hz otherwise.

In a way I can understand it though, why release a 120Hz monitor that only works with like 2% of Macs out there at the moment? Once market share of TB5 is higher, we'll see 120Hz 5k devices take over.
 
One does: the CMF-1. The most common refresh rate for android phones is 60Hz. 120Hz is mostly reserved higher-end phones costing $800 and above. Nothing, maker of CMF-1, is the outlier who could push the industry in the right direction. However, they are a relatively new player with a minuscule market share. While their displays are excellent, their cameras have been criticized for color inconsistencies, poor low-light performance, exposure instabilities, and limited dynamic range. So, for $200, you can get a good display, but you are going to get a lousy camera. TANSTAAFL.
And tiny or negative profit margins.
 
How much noticeable difference between 90Hz and 120Hz? I already don't notice anything different between 60 and 120Hz unless I'm looking for it, but I'm not gaming.

Would there be any benefit to going halfway to 90Hz? Is that enough bandwidth savings that a MacStudio would be able to drive three 27" displays at 90Hz instead of two at 120Hz?
It's a personal thing, I can definitely see a huge difference when using my mother's 50Hz MacBook Air 13 vs my MacBook Pro 14, now I can never go back from 120Hz. I'm pretty sure I could see 90Hz vs 60Hz. The question is whether it bothers you or not.
 
I already have a reasonably priced 5K2K monitor ($725), and it has 120Hz refresh rate and a zero dead pixels guarantee. Some gamers have groused about the pixel response rate being "low" (i.e., not 2ms), but I haven't noticed any ghosting or blurriness, so I suppose it's well-matched to 120MHz. Anyway, I mainly do Microsoft Word, email, and light video editing of a guy mainly sitting in the same place and talking. If it were NASCAR or UFC maybe I'd be dissatisfied.

Apple Studio Display at 90Hz is a Don't Buy! for me. A shame, as I have heretofore been a pretty solid customer for Apple displays.
what model display do you have?
 
Hey look, I twisted this apple stem many times and it broke at 90 - let's make a monitor with that refresh rate!

Yeah, in 4 years they will decide the refresh rate based on the radio frequencies: 114.8Hz...
Can't innovate my.....

Good observation. Thunderbolt 4 is 40Gbps and can support a 5k or 6k monitor at 60Hz. A 90Hz 5k monitor requires 31.85Gbps and a 120Hz 5k requires 42.36Gbps. So 120Hz 5k is just out of range for Thunderbolt 4.
 
I doubt this rumor (from a random anonymous source...) is valid. Simply too much 60Hz content out there which do not scale nicely to 90Hz (every second frame needs to be doubled or interpolation/telecine is needed, both are awkward and result in a substandard experience). 90Hz is certainly not an ideal choice for a computer monitor.
 
VFR, please. 24fps video can’t play back smoothly on static 60Hz or even static 90Hz screens — it has to be subjected to pulldown techniques. And it causes a visible wobbliness that you can’t unsee once you’ve noticed it.

Ideally a screen would be capable of variable refresh rates that are multiples of 23.976, 24, 29.970, and 30.
 
With Thunderbolt 5 there's no reason to make it less than 120hz

Ummmmm, it's Apple Inc. Hype & sell lots of monitors at 90hz in 2025, then roll out 105hz in 2027 and 120hz in 2029... and 120hz Model B in 2030. Can also work 27", 28", 29", 30" evolutions too. Extract that 💰💰💰 Feed them shareholders families. ;)

Well, that’s been the default for other display manufacturers for 10 years now, so - Ah yes, now I see your concern…

😜
 
I’d be excited for this simply because there would probs be some good close out sales at best buy or amazon on the previous model.
