At least on the pre-'05's, that adjusting screw inside the fairing is the main vertical adjustment for the entire headlight. The knob on the dash is for fine tuning for load, two-up etc.
From the Service Manual:
• Set suspension preload to “LOW” (turn counterclockwise).
Make sure that the adjuster on the instrument-panel
cover is at the “UP” position (turned counter-clockwise
as far as it will go).
• If necessary, turn the adjuster on the instrumentpanel
cover counter-clockwise as far as it will go.
• Manually adjust the headlight beam throw by
turning the adjusting screw (1) beneath the fairing
upper section with the aid of the headlight
Setting for headlight beam angle adjuster
....... .-10 cm (-3.94 in) (from vertical) at a distance of 10 m (32.80 ft)
Turned to left............................ longer throw/higher
Turned to right ......................... shorter throw/lower
If necessary, laterally adjust the headlight beam
angle by turning the adjusting screw (2) at the top
left of the headlight with the aid of a cross-recessed
