I run Linux on my gaming PC, single monitor, 1440p w/ FreeSync. I'd like to get a second monitor (most likely 1080p) so that I can chat in Discord or look something up on a game's wiki without Alt+Tabbing out of the game (or at least without having to bring up the browser on top of the game itself).

I've searched the internet, and I see that I'm not the first to ask this question. That said, I see some conflicting information out there—some responses claiming it works out of the box, or it works but "oh I didn't check the refresh rates tho." ~ archived Reddit thread from 2020

Here's another example of a forum post from 2023 where responders claim it doesn't work.

But other people claim it does work, so.... does FreeSync work with multiple monitors on Linux? Does it matter if I'm using Wayland or X, Gnome or KDE, AMD or NVIDIA, etc?

EDIT: I want to thank everyone for their input. Over the weekend, I got a cheap (under $100) 1080p display to use as my second monitor while gaming, and so far, I couldn't be happier. Thank you!
