CLOCK (pixel frequency) controls the number of pixels scanned by one

horizontal sweep. If the frequency is not correct, the screen shows verti

stripes and the picture has not correct width.

FOCUS adjusts the phase of the pixel clock signal. With a wrong phase

adjustment the picture has horizontal disturbances in light picture.

For FOCUS and CLOCK adjustment use ￿dot-pattern￿ or win 95/98 shut-

down mode pattern.
