 Interpolated Resolutions: When resolutions are shown that are lower than the pixel count of the LCD module, text may

appear different.  This is normal and necessary for all current flat panel technologies when displaying non-native
resolutions full screen. In flat panel technologies, each dot on the screen is actually one pixel, so to expand resolutions to
full screen, an interpolation of the resolution must be done.
