FreeSync range understanding...

[dmab]

Greetings.

Explain to me, a beginner, about changing the FreeSync range.
Why do this and how to properly test validate what you did?

I understand that when, for some reason, the monitor / videodriver sets a smaller FreeSync range than stated in the documentation for the monitor, then it makes sense to force it to be corrected using CRU.

Another option is when we want a larger range than stated in the documentation for the monitor. Then how much to increase it and how to check if these changes work correctly?

Thanks.
