  • Enable local dimming.

Dark portions are pixelated

  • Enable noise removal settings.
  • Improve connection (if streaming) or source quality (if low-quality).

Grain on the picture

Note: Normal for movies.

  • For other content, enable noise removal settings.
  • Improve connection (if streaming) or source quality (if low-quality).
  • Reset colour space and white balance settings.
  • Try different HDMI cable and different HDMI input on the TV.

Picture looks out of focus

  • Disable motion interpolation.
  • Increase ‘Sharpness.’
    • This makes the picture a bit less accurate.
  • Adjust the aspect ratio setting.

Note: Low-quality media often looks fuzzy, so if those first steps don’t help, the only solution is to watch higher-quality video.

Sparkles/banding appearing on screen after calibration

  • Reset white balance and colour space adjustments to default.
  • Try a new HDMI cable.
  • Try different picture mode.
  • Return, or contact manufacturer support.

Stuck pixels on screen

  • Connect PC to TV, use this tool to fix the stuck pixels.
  • Try applying gentle pressure on the stuck pixel. Turn the TV on, and then off, then check.

No other fix. If many stuck pixels, return, or contact manufacturer support.


TV not outputting sound

  • Make sure HDMI or audio cable(s) are securely connected to both TV and receiver/headphones.
  • Make sure TV is set to output audio to your source device (sound settings).
  • Make sure source device is outputting compatible sound (PCM, DTS, Dolby Digital are safe bets).
  • Try different audio cable.
  • See if other devices can play on the receiver.
  • If the receiver does not work for anything, contact the receiver manufacturer’s support.
  • If the receiver does work for other devices, contact TV manufacturer’s support.
