*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 fl at panel technologies when displaying non-native resolutions full screen. In fl at panel technolo-

gies, 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 specifi cations are subject to change without notice.
