Proper Channel

• If you are watching television and you see black lines on the left and right sides of the screen, check to see if you are watching an HD broadcast or a standard definition broadcast. You can do this by bringing up the TV guide menu on your remote. If the show is in HD, it should take up the full screen. However, if it is not HD, bars will be present on the left and right of the screen. That is because standard definition programing is in 4x3, which will not take up the entire screen.
  
  

Zoom

• If the picture you are watching not only has black bars on the sides, but on the tops and bottoms of the screen as well, your "Zoom" mode has somehow gotten off-kilter. Press the "Zoom" button on the Mitsubishi's remote until the image appears correct. If this does not work, power down the television, wait a few moments, and power the TV back on. The image should be correct now.
  
  

Stretched Image

• If the image on the screen looks stretched or squished, this is because your HD cable receiver is not set up properly for your Mitsubishi HD widescreen television. Press the "Menu" button on the receiver's remote. Navigate through until you find "Options." Under the options you will find "Aspect Ratio." Select this, then choose the proper resolution that matches your television (such as 720 or 1080). Once this is selected, press "OK." The image on your Mitsubishi widescreen television will now be correct.
