I agree, from memory windows will prefer a 60hz rate at the highest resolution until the user (or “monitor .inf file) overrides it.

I kind of feel MacaOS does the same - indeed a quick test shows my monitor at 60hz even though there is a free sync range from 40-90 in the refresh rate. But of course this is a weird situation since it’s a free sync thing too, so I couldn’t apply it to everything.

So on that note, I go back to my original theory that it’s the graphics driver (or xrand or one of those x-things) screwing the timings up.
