Lets look at the default case, that creates a 100x100 pixel image. The default target dpi is 72, so 100/72 = 1.388888.
If you set the target dpi to 204, then the image needs to be 283x283 pixels because 204*1.38888 = 283.3333. Then a 1 pixel line needs to be 2.83 pixels to keep the scaling correct. Since you cannot have 2.83 pixel thickness in the monitor, it defaults to 3 pixels. Is your goal to print (to paper) a line of a certain thickness? Then you need to talk about dimensions (say, mm) not pixels.
