“COARSE” (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 does not have the correct width.

“FINE” adjust the phase of the pixel clock signal. With a wrong phase adjustment the picture has horizontal disturbances in light picture.

For “FINE” and “COARSE” adjustment use a dot pattern or Windows 95/98 /ME/XP/2000 shutdown screen.
