A WORD ON INTERPOLATED RESOLUTIONS:
When resolutions are shown to be lower that the pixel count of the LCD module, text may appear chappy or lines may appear to be bold.
This is normal and necessary for all current fl at display 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. When the interpolated resolution is not an exact multiple of the
native resolution, the mathematical interpolation necessary may cause some lines to appear thicker than others.
