What is output by `xrandr --verbose`? If EDID information is being reported properly, it should show you the possible resolutions for your monitor (presumably containing 1680x1050, since that's what you're expecting.) if not, It may be that your EDID information is goofed and you need to tell Xorg to augment that information with more resolutions by adding modelines to your Xorg.conf (or however the hell it's supposed to be done now)
