This is used as the minimum refresh rate in the variable refresh rate range. This value is expected to be found in the DisplayPort and eDP EDID of every monitor that supports variable refresh rate. It is also found in the HDMI EDID of some monitors that support variable (FreeSync), but most likely not all of them. The rest require parsing the AMD vendor extension which libdisplay-info doesn't support. No fallback is implemented for cases where libdisplay-info support is disabled.
