The cutoff of the screen is due to something called "overscan". While most TV's will automatically fit the input image to your screen, some TV's may cut off a little part of the screen - about 2-5% - and stretch the remaining image to fit the screen.
The solution for overscan will vary depending on your TV. If the below tips do not work or if you are not able to find a specific setting in your TV menu, please refer to your TV manual or contact the manufacturer of your television for further information.
