I first noticed that my HDTV was cutting off portions of my DVDs' picture when I watched a 1.85:1 movie and was unable to locate the thin black lines that should be at the top and bottom of the screen. A little research showed that this was the result of something called "overscan". I'm anal retentive about seeing the whole picture, so I was wondering how to disable this overscan. A person at the AVS Forum suggested accessing the service (or factory) menu for an answer, but I have only located a single site with instructions on how to do this, and their methods do not give me access to the menu. Does anyone here happen to know how to access the service menu for a Vizio VX32L, and, if so, what to adjust to eliminate overscan? I understand the controls are highly sensitive, so I don't want to change something unless I know what it does.

Thanks in advance!
