The picture is interrupted at the beginning of a DVD or Blu-ray disc playback.
IMPORTANT: Not all Blu-ray Disc® players or Blu-ray Disc home theater systems have the same capabilities. Manuals are posted on your model support page.
This may occur if an inserted disc has a different resolution than the disc that was previously played. It happens if the HDMI Resolution option in the Output Video Format settings of the Blu-ray Disc player is set to Original Resolution. To prevent this momentary picture interruption, change HDMI Resolution to Auto.
