CLOCK (pixel frequency) controls the number of pixels scanned by one
horizontal sweep. If the frequency is not right, the screen will show vertical
stripes and the picture will not have the right width.
FOCUS adjusts the phase of the pixel clock signal. With a wrong phase
adjustment the picture has horizontal disturbances on light pictures.
For FOCUS and CLOCK adjustment use "dot-pattern" or win 95/98 shut-down
mode pattern.
