It's mind-boggling that Apple is considering the base 27 inch Studio Display with the same 4 year old panel, but with some new accessories slapped on an "upgrade".
The 5k iMac was introduced in 2014. There was one change in 2015 that added P3 color gamut, so it appears to have been the exact same LG-manufactured panel for at least 11 years.
Oh, and if you want to utilize 120Hz on the XDR display, you're going to have to replace your perfectly functioning Mac.
> Mac models with M1, M1 Pro, M1 Max, M1 Ultra, M2, and M3 support Studio Display XDR at up to 60Hz. All other Studio Display XDR features are supported.
Can you point me to said list? All I could find was:
> Mac models with M1, M1 Pro, M1 Max, M1 Ultra, M2, and M3 support Studio Display XDR at up to 60Hz. All other Studio Display XDR features are supported.
And The Verge reports:
> There’s also support for adaptive sync that can adjust between 47Hz and 120Hz (if it’s connected to an M4 Mac or later, or the M5 iPad Pro)
I got an M3 Max and was strongly considering upgrading my old monitor, but if I can't do 120hz, I'll just wait until I upgrade my laptop as well.
It’s quite possible this is running with a reduced color space (chroma subsampling). Degradation happens automatically based on available throughput and most people don’t notice.
There’s no list per-se. The MacBook Pro (2021 and later) is listed as supported. The M3 Pro and M3 Max are not listed as only supporting 60Hz while the M3 and M1 Pro are.
I don't really see your point. The chips mentioned do not have enough bandwidth on display outputs to support the monitor at 6K@120Hz. If anything, I find it surprising that Apple supports running the display in 60Hz mode instead of telling people to go pound sand and buy new Macs.
