Since you don't mention how you're receiving the signal, I'm assuming you use a cable box or computer. Adjust the output settings (e.g. 720p, 1080p) on the box and then adjust your TV settings. If it's a computer, you'll need to adjust the video card settings to a compatible aspect ratio (e.g. 1366x768) for the desktop to display properly on the TV. Details can be found in the owner's manual.
