Some other devices, DVD or Blu-ray Disc players, might
have their own picture quality processing. To avoid

should be disabled. The TV comes with Pixel Plus link
switched on and disables the picture quality processing of
a connected device.
To switch off Pixel Plus link, press h > Setup > TV settings
