TECHNICAL SUPPORT (FAQ)
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 95/98/2000/ME/XP/Win 7 shut-
down mode pattern.
