I think you will find that the flip out screen does not show the whole picture on the AF100. It has actually been a complaint of mine about Panasonic products since the DVX 100. More than a few time I have been nailed by frame boundary issues when relying on the flip out screen alone. A mappable function to a user button for under scan would be a genius move on the part of Panasonic.And what is up with the black text on a dark slate colored back ground for this site. At least that's how it looks on. My iPad. Talk about not being able to see what is going on!
