 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 ß at panel technologies when displaying non-native resolutions full screen. In ß at 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. 

NOTE: Technical speciÞ cations are subject to change without notice.
