Not getting full refresh rate of monitor

I have a Samsung Odyssey G9 monitor, which can display 5120x1440 at 240hz - this works in Windows just fine, although in Monterey (and Linux) I can only get that resolution at a maximum of 120hz. If I lower the resolution I can get 240hz but of possible I'd like to get the full experience out of it.

So, for Windows and Linux, I use a 2080ti and under macos it's an rx570. Only Windows seems to do everything.

If I can provide any other information please let me know!
