We have had this Vizio P42HD for 2 or 3 years. Suddenly, the picture has shrunk. There are two settings which control picture size: Zoom and Wide. We've always had Zoom=normal and Wide=aspect. We can now get an HD signal to fill the screen only by setting Zoom=Zoom2 and Wide=Wide. This fills the screen, but it seems like there is some distortion and, I think, picture degradation.We've tried every setting we can find on the TV and had the cable guy out at well. I'm fairly certain it's not the signal because the picture has shrunk from all sources (cable box, dvd player, XBox).The only guess we've come up with is that in the Setup menu it shows the resolution as DVI: 480P. This is labeled as "Info" and doesn't seem to be changeable. The specs say that the TV is capable of 720P. Can anyone suggest how we could change the resolution to 720P, or why we can't? Can anyone suggest a different cause for our shrunken picture?
