on TFT displays, fuzziness usually is a result of displaying a 
resolution that is not native to the display.  For example, if your 
displays native resolution is 1600 by 1050 and you send it 1280 by 768 
video, it will be fuzzy because the display circuitry interpolates what 
is given to the native resolution of the display.

RTFM, determine the native resolution of the display and adjust your 
video accordingly.
