Poor picture
Picture quality not as good as

(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.

Signal Diagnostics

Product
Support
settings (page 31). Then select
Sample Image

Additional
