   (The discussion was about plotting 2-high pixels in the 640X200 mode)
   No, you don't have 640 X 200 virtual pixels.  You have 640 X 399 screen
locations which can hold a pixel, which pixel is two lines high. For example:

Screen lines -->  X.........   Note the pixels are composed of two dots (what
                  X..X......   are normally called pixels), and that adjacent
                  ...X..X...   pixels can overlap by one line.  This means 
                  ......X...   that the ONLY structures on the screen which
                               will lose resolution are those which are 
made up of only one vertical dot.  I would like to see someone construct
a high-res font which uses this principle - I think it would look GREAT!
