TECHNICAL SUPPORT (FAQ) (cont.)
CLOCK (pixel frequency) controls the number of pixels scanned by
one horizontal sweep. If the frequency is not correct, the screen shows
vertical 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.
