The pixel clock should be adjusted mainly for computer-
related inputs. (Normally, it does not need to be adjusted for
video inputs.) If a wide stripe appears on the screen, adjust
the lateral size of video image and the display area (tracking
adjustment) so the stripe disappears.
Also, if text on the video screen appears flickering or dim,
make adjustment so it becomes clear (phase adjustment).
