I see "noise" or static on the screen.
• When your TV's digital capabilities exceed a digital
broadcast signal, the signal is up-converted (improved) to
match your TV's display capabilities. This up-converting
can sometimes cause irregularities in the image.
• If you are using an antenna, the signal strength of the
channel may be low. Ensure your antenna is connected
securely to the TV and move the antenna around the
room or close to a window for the best signal.
When I change input source, the display image changes size.
• The TV remembers the viewing mode on each input
source. If the viewing mode on the new input source
differs from the one on the input source you switch from,
the difference may be noticeable.
• See Changing the Screen Aspect Ratio on page 24.
