Notes
• The selected item is shown in magenta color. Items shown
in gray color cannot be operated or set in the current mode.
• A dim screen could be caused by insufficient adjustment of
brightness and contrast. Before adjusting phase, make sure
that brightness and contrast are correctly adjusted.
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
