Explanation/Solution
• Confirm the PC is correctly connected to the TV with either the PC IN (with an
HD15 cable) or with the HDMI IN.
• Ensure the output signal from the PC is one of the formats listed on page 14.
• Turn the PC off. Confirm the PC connection and restart the PC. Plug-and-play
will auto-detect the TV and correctly set up PC timing.
• Verify PC Power Management is activated (see page 52).
• Verify the PC is not in standby or hibernation mode.
• Adjust the resolution (see page 14).
• Adjust Pitch and Phase.
• The current Wide Mode setting is automatically replaced with the 4:3
Default setting when you change the channel or video input, if 4:3 Default in
the Screen settings is set to other than Off. If you want to lock in Wide Mode
selected with WIDE on the remote control, set 4:3 Default to Off in the
Screen settings (see page 44).
• Check the Auto Wide option in the Screen settings (see page 44).
• The picture gets smaller during the commercials due to the method in which the
provider broadcasts their content. When HD content channels switch to SD
content (commercials), the picture may be small with a black border.
• Auto Wide will not expand the picture during these content changes since the
content information is regulated by the channel signal provider. You can
manually change the Wide Mode if you prefer (see page 21). This setting will
remain in effect until you change the channel or input or manually change the
Wide Mode again.
• You have selected a text option and no text is available (see page 47). To turn off
this feature, set the CC Display option to Off. If you were trying to select
closed captioning, select CC1 instead of Text1-4.
• Some wide screen programs are filmed in aspect ratios that are greater than 16:9
(this is especially common with theatrical releases). Your TV will show these
programs with black bands at the top and bottom of the screen. For more
details, check the documentation that came with your DVD (or contact your
program provider).
• Programs in 4:3 aspect ratio will have bands on left and right sides of the
screen.
• Programs broadcasted in HD formats (720p and 1080i) with 4:3 content will
commonly have black bands on the left and right sides of the screen which are
added by the broadcaster (see image on left).
• Auto Wide will not expand the picture when the black bands on the sides of
the screen are added by the broadcaster. You can manually change the Wide
Mode to Wide Zoom, H Stretch or Zoom to fill the screen, which will
remain in affect until you change the channel or input or manually change the
Wide Mode again.
• This is due to the digital compression of the source content used by certain
digital broadcasts and DVDs which may cause your TV's screen to display less
detail than usual, or cause artifacts (small blocks or dots, pixelations) to appear
on your screen. These signal compressions are more visible and are dependent
on the clarity and resolution of the TV.
• To determine if the problem is with the remote control or not, press a button on
the TV.
• Check the polarity of the batteries or replace the batteries.
• Point the remote control at the remote control sensor located at the front of the TV.
• Keep the remote control sensor area clear from obstacles.
• Fluorescent lamps can interfere with your remote control operation; try turning
off the fluorescent lamps.
