I was given a 23-inch diagonal monitor and desktop that has all three
colors (blue white & hdmi) and the desktop can output blue white or hdmi
but the owners who gave it to me couldn't find the cables.

Does it matter in the "quality" of the end result which cable I buy?

I interpret "white" as being DVI and "blue" as being VGA, since those seem
to the industry-standard colours for the plastic insert with the pinholes in
it (in the socket) and the plastic shroud (on the plug).

Good question: faced with a graphics card that can produce all three outputs
(at the same resolution) and a monitor that can accept all three inputs, is
there a preference for HDMI over DVI over VGA? I'm assuming digital, not
analogue, outputs on DVI and VGA, so different contact resistance will not
cause colour cast or missing colour, and cable capacitance will not cause
ghosting/blurring.

I suppose one advantage of HDMI is that the same cable can also carry the
sound.
