      <p>This dialog contains a number of tabs, each with a number of fields. Note that beneath the tabbed sections is a
        non-editable field that presents your selected options, command-line style, as they will be passed to the
        emulator when it is started. See <xref

        <strow>
          <stentry><uicontrol>Screen Resolution</uicontrol></stentry>
          <stentry>A DPI value that represents a scaling factor to be applied to the emulator window. This allows you to
            alter the emulator's screen resolution to match the screen size of an actual device. By default, this value
            is 165. Click the <uicontrol>Calculate</uicontrol> button to calculate screen resolution and scale values
            that result in a life-sized image given the screen size of the device being emulated (in inches) and your
            development computer's display size (in inches) or density (DPI).</stentry>

        <strow>
          <stentry><uicontrol>Scale</uicontrol></stentry>
          <stentry>A value ranging from 0.1 to 3.0 that represents the scaling factor to be applied to the emulator
            window. To specify the scale as a DPI value, include a suffix of "dpi". Click the <uicontrol
            >Calculate</uicontrol> button to calculate screen resolution and scale values that result in a life-sized
            image given the screen size of the device being emulated (in inches) and your development computer's display
            size (in inches) or density (DPI).</stentry>

          <stentry>Hides the "skin" that makes the emulated device look more like a specific handheld. Note that the
            skin includes the device keyboard (if the emulated device has a physical keyboard); hiding the skin makes
            this keyboard, along with any other physical controls presented by the emulated device, inaccessible. Also
            note that if you change this option on a running emulator, you will need to stop and restart the emulator
            for the option to take effect.</stentry>
