Remedy
Check the position adjustment settings, and adjust the screen settings
accordingly.
Press the Aspect button on the remote control to select a different picture
image size.
If the image is from a PC DVI or HDMI connector, you may experience
over-scanning or under-scanning, where the image is larger or smaller
than the screen. Consult your PC manufacturer display drivers about how
to resize the image settings, if they are available.
Verify that the external device or PC resolution setting is correct. Adjust to
the appropriate resolution.
Press the Info button on the remote control. and read the station
transmission mode. Some stations transmit standard-definition
programming directly in the 16:9 aspect ratio, so the image has
embedded dark side bars. For that type of input signal, the Panorama
mode is not available, and the Zoom1 and Zoom2 modes do not
eliminate the side bars.
Film may be captured in many different widescreen ratios. When the
original film ratio does not match the TV ratio, the stripes appear above
and below the image.
