Donald is dealing with a horizontal crop issue on his TV. He tried to change the aspect ratio, but all he seems to be able to do is zoom it in, which doesn't help. Leo says that there could be a fit screen option that's been enabled. It could be called Zoom or Stretch. Underscan may also be the option. Try looking for that and disable it. Also, look for 1-for-1 / 1:1.or 16:9. Some movies may end up with letterboxing however. If it does, then zooming it will distort the image and crop off the image like that. So check your aspect ratio settings.
If that doesn't help, it's likely a hardware issue and since Don's TV is 10 years old, it's time to get a new one.
