I’m trying to understand what is the range of the variable refresh rate implemented by AMD FreeSync, and information is pretty vague about the minimal value:
The range of refresh rates supported by the standard is based on the capabilities reported by the display.

Q: What is the supported range of refresh rates with AMD FreeSync technology and DisplayPort Adaptive-Sync?
A: Compatible graphics cards support a wide variety of dynamic refresh ranges with AMD FreeSync™ technology. FreeSync capable graphics cards can detect and set the appropriate maximum and minimum refresh rate based on the capabilities reported by the display. This means FreeSync supports up to the maximum refresh rate of the display itself.

Additionally i’d like to mention Freesync typically has a bottom range of 40Hz, not allowing you to have native 24Hz support. I’m unsure of wether it will switch to 48Hz as a best alternative.

The maximal value is just the maximal refresh rate of the display.
But what is the minimal value? Let’s say that I use a 120Hz, can I play games that run from something like 30 to 90 FPS and benefit from Variable Refresh Rate?
If there is no standard value, what are the minimal values for some examples of screens?
