If you have a TWC remote, press settings on your remote. A menu should appear. Use the left arrow that is near the top. Scroll the menu at the bottom of the screen to the left till you see high definition . A screen will appear one of the choices will be picture size. Use the blue select/ok button to select picture size. Another screen will appear and it will say zoom, normal and stretch . Scroll to normal and select it. This should solve your problem. Other cable companies remotes should be similar . You usually can do the same using your Tv remote. I hope this helps.
