Vista - Poor Sharpness Of Photos In Windows Photo Gallery

Hi,
Please has anyone found a solution to the poor sharpness of Photographs in
the windows Photo Gallery and the slideshow in Windows Media Centre. My
Camera image software produces fine sharp Photos. I was wondering whether the
problem was with my monitor as it is analogue SVGA and vista may be designed
for digital monitors. I don't know, can anyone shed any
light..............thanks
