*1 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.
