Authored by: Support.com Tech Pro Team

  1. Use the Up and Down buttons on your remote, then push the central OK button to select one.

3. Check Input Device

Sometimes, it's not a problem with your TV, but rather with the device sending pictures and sounds to your TV.

  • Try testing another device, first. For example, if you're watching cable, try switching to DVD or Blu-Ray, and play something there. If that works, it's most likely not a problem with your TV, but rather the device that's sending the programming your TV is showing.
  • Try turning your cable, DVD, or Blu-Ray player off, waiting a few moments, then turning it back on, and try again.
  • If one device works fine (say, your DVD or Blu-Ray player), but another does not (say, your cable box), it would be best to contact the provider of the device that isn't working.

4. Exit Menu

To exit the menu, push the 'Return' button, or wait about 30 seconds for it to disappear on it's own.

To go any further, we need to determine the type of video issue you are experiencing.

8. Aspect Ratio

Your Smart TV has a 16:9 aspect ratio; some older programming was created in a 4:3 aspect ratio, and many movies have a 21:9 aspect ratio. This will cause black bars to appear on the top and bottom, or left and right. You can zoom, stretch, or restore these with theFormat button, as well.

  1. Push the Format button on your TV remote. You can push this a couple times to cycle through the options quickly.
