How Do I Configure ATI Radeon HD 4650 GPU to display on my HDTV?

What you will need to do is allow your computer to detect the settings and change the default display to your TV. The easiest solution I have for you is connect both your PC monitor and your TV to the computer. Once your computer is booted up, you can change the settings and set your TV as your default display. You can do this under windows display properties or ATI CCC.
