How Can I Fix My Ps3 Hdmi Problem?

When I use and HDMI cable with my PS3, some of the screen gets cut off. I've tried setting the screen size so that it wouldn't be like this but it seems like nothing helps. Any suggestions?

Suggestion:

Depends what TV you have. I have a 42" Samsung LCD and had the same problem for a while. All I had to do was hit the "Picture Size" button on the remote and change it to 'Just Scan' mode.

Alternatively, check the TV options to adjust the screen's placement.
