This happens because the default PointSize is smaller than 
the pixels on your display.

You can use the PlotStyle option to specify a larger point 
size (using the PointSize primitive). 

    ListPlot[{1,2,3}, PlotStyle -> PointSize[.05]];

You can also use SetOptions to change the default value 
(and if you place the SetOptions command in your init.m 
file the default will be changed for every Mathematica 

    SetOptions[ListPlot, PlotStyle -> PointSize[.05]];


The Technical Support FAQ area of Wolfram Research's web 
site includes a page discussing more possibilities for 
changing default PointSize options:

I hope this helps.
