Turns out Windows scales the resolution reported from GetDeviceCaps and GetDpiForSystem.

In addition, the so called "raw" resolution reported by GetDpiForMonitor appears to be
more inaccurate than the default Windows resolution. Therefore, Meazure will use the
default Windows screen resolution (96 DPI) as the default for the uncalibrated
resolution.
