I think the DPI of the monitor would still be valid in the vmware window, just set it to that of your physical monitor and I think it should be the same. The size of 1 pixel in the vmware window should be the same as the size of 1 pixel in your monitor normally. If your two monitors are not the same DPI then things could be complicated though. I don't use multi-monitors so I'm unfamiliar with how that would work. In my Xorg.0.log I see these lines among others from the Nvidia driver initialization: (II) NVIDIA(0): Virtual screen size determined to be 2048 x 1152 (--) NVIDIA(0): DPI set to (101, 100); computed from "UseEdidDpi" X config (--) NVIDIA(0): option Not sure how it works for other video drivers. On this one, at least, the DPI is set automatically.
