Mine supports variable refresh rate, which means for most desktops tasks (I.e when nothing is moving), it runs at 48Hz.

Incredibly, Linux has better support than windows for it on the desktop: DWM runs full blast, while sway supports VRR on the desktop. Windows will only enable it for games (and games that support it). Disclaimer: Wayland compositor required.

It’s not enabled by default on e.g. sway because on some GPU and monitor combos, it can make the display flicker. But if you can, give it a try!

Windows 11 idles at around 60 Hz in 120 Hz modes on my VRR ("G-SYNC Compatible") display when the "Dynamic refresh rate" option is enabled, and supports VRR for applications other than games (e.g., fullscreen 24 FPS video playback runs at 48 Hz* via VRR rather than mode switching, even with "Dynamic refresh rate" disabled).

* The minimum variable refresh rate my display (LG C4) supports is 40 Hz.

I use KDE + Nvidia, and last I looked into it, it only worked if you had one monitor enabled. That's fine for gaming, not for working.

But it has been a while since I've tried it, maybe I should look into it again
