Oh yeah for sure, it works great when I set my monitors to the same refresh rate, but I'd prefer to not have to do that because it's a pretty big difference between them. My secondary monitor is 165hz, but my primary monitor is 360hz, and trying to run them at their native refresh rates at the same time in X11 doesn't work at all. I'd have to set the 360hz monitor down to 165hz to match my secondary monitor before things become usable.
