ô__ô ! Holy pluck, I didn't know that!
... I don't think it'd work on my monitor, though. From my understanding, it looks like only newer G-sync monitors made since 2020 or maybe mid-2019 support Freesync. But I bought mine (Acer Predator XB271HU) in January 2019. I'll search a little more, just to be sure...
In any case - thanks so much for letting me know, and for the link! Much preesh. : )
