Poor picture
Picture quality not as good as

• Picture quality depends on the signal content. See Quick Setup Guide
(supplied) to display the best possible picture for that signal.
Broadcast HD formats have
poor quality
• Content and signal quality are regulated by the signal provider. Many HD
channels and content are actually upscaled versions of standard-definition
broadcasts. The picture is affected by the quality of the signal received, which
varies between channel and program.
• Confirm the picture quality by selecting
Signal Diagnostics
in the
Product
Support
settings (page 31). Then select
Sample Image

Additional

it is most likely due to the signal provided by the broadcaster.
