Possibly. If you have the option to use DisplayPort instead of HDMI, that should also resolve it today.
I think it also depends on what distro you’re using. On Linux Mint Cinnamon, which still uses X11 by default, I haven’t been able to use the highest refresh rate of my monitor. But the experimental Wayland support did it without issue.
I can get 5k widescreen 120 on windows, only 1440p 60fps on linux, is this going to help with that?

I’ve gotten 280 fps with matching refresh rate on Linux and X11, as well as Wayland. All using DisplayPort of course. Works great.
