Eli5: Why can’t we choose a specific screen refresh rate on phones?

Question

Why is it always 60 or 120 or 144? Why can’t I input the value I want (for example, 90 or 100 or even 87)?

Edit: FYI, my phone is a Motorola Edge 40.

Answer 1

It’s an artificial limitation, and so the reason for it can only be speculated. Which I’d reckon goes something like why expose a configuration option that isn’t meant to be reconfigured.
