Olevia 427V (Set Aspect ratio to 1:1 mode). Envision 37" (Set aspect ratio
to no scale). It's done different but the end results are the same.

Hmmm... My cousin has a Vizio 37" and I'm pretty sure it does. But it
isn't in the menu IIRC. Only on the remote.

Well, I just set both my HDTV's to normal aspect ratios. I watch
everything through my PC recorder system which will let me manipulate the
picture any way I see fit. Now I wouldn't want to make the image smaller,
but when I get a 16:9 picture in a 4:3 image I can just use 16:9 zoom to
take it right back to full screen. There's quite a few shows like this I
watch. I really haven't checked to see if the TV's will do this on their
own.... Well, the Envision zoom x2 mode does exactly that. Zoom modes are
1/4, 1/2, x1 (normal), x2, and x4 on it. Can't get to the Olevia to test
it now, but I'm pretty sure it will also do it.
