It uses DDC to download your monitor's specs from the monitor itself, then
matches it up to a set of builtin modelines at the given bitdepth. I
think it prefers resolution over refresh, but it depends on the limiting
factor, the card's clock or the monitor's frequency ranges. Looking at
the output in /var/log/Xorg.0.log should illuminate its choices.
I generally end up adding a DefaultDepth and a Modes line at that depth to
force the resolution a specific way. I haven't ever tried Xorg -configure
-depth 24 and see if it spits out a DefaultDepth line...
