Additional Information
Possible remedies
• When connecting a Macintosh computer, use an
adapter (not supplied) if necessary. Connect the
adapter to the computer before connecting the video
signal cable.
• Using the menu system, select "Adjust Pixel" option in
the "Screen Control" menu and adjust "Dot phase" or
"Total H Pixel" (page 30).
• Try connecting the Plasma TV to a different AC power
outlet, preferably on a different circuit.
Problems caused by the connected computer
• Check your graphic board manual for the proper TV
setting.
• Confirm that the graphic mode and the frequency of
the input signal are supported by this Plasma TV
(page 63). Even if the frequency is within the proper
range, some graphics boards may have a sync pulse
that is too narrow for the Plasma TV to sync correctly.
• Adjust the computer's refresh rate (vertical frequency)
to obtain the best possible picture.
• Using the menu system, adjust "Bright" and "Picture"
in the "Picture adjustment" menu (page 26).
• Using the menu system, select "Adjust Pixel" option in
the "Screen Control" menu and adjust "Dot phase" or
"Total H Pixel"(page 30).
Problems caused by the connected computer
• If the resolution is more than the numerical value
specified in "Specifications" on page 61, the picture is
reduced in size and the picture quality may be less than
the original. This is not a malfunction.
• Eliminate the use of video cable extensions and /or
video switch boxes.
• Check that all plugs are firmly seated in their sockets.
• Using the menu system, select the "Screen Size/Shift"
option in the "Screen Control" menu and adjust "V
Size" (page 30).
• Using the menu system, select the "Screen Size/Shift"
option in the "Screen Control" menu, and adjust "H
Shift" or "V Shift" (page 30). Note that some graphic
modes do not fill the screen to the edges.
Problems caused by the connected computer
• Set the resolution of the connected computer to the
same as the Plasma TV.
• Using the menu system, select the "Adjust Pixel"
option in the "Screen Control" menu and adjust "Dot
phase" or "Total H Pixel"(page 30).
• Using the menu system, select the "Adjust Pixel"
option in the "Screen Control" menu and adjust "Dot
