HiDPI unavailable on 5k monitor (5120x2880) (Not ultrawide)

[yonson2]

Hi!

I'm trying to configure my monitor but I'm unable to make it work as HiDPI on it's full resolution (its a 27in 16:9 5k monitor), the maximum resolution HiDPI option available is 2560x1440.

I'm currently plugging it to a MacBook pro m1, is it impossible because of the max vertical HiDPI resolution limits for m1/m2 chips?

I do have "Enable resolutions over 8k" enabled.

But unfortunately:

I'm I out of luck?

As it turns out, 2560x1440 HiDPI is 5k.
