is there anyway to get more setting on zi8.. i wanna adjust 720p output scaling

. Because 1080P fits perfectly on my 40" screen pixel to pixel i have an option on my tv called "full pixels" using that option 1080p/i fits perfectly but 720 scales to small picture in the middles of the screen.. yes i understand that but that's not what i'm trying to say.. when 720p is scaled to the original size i can choose full mode instead of full pixels mode and 720p fills the screen but not perfectly some of the picture goes off the screen i was wondering if could adjust it. Thanks... if you don't get what i'm trying to say don't bother to understand it.. sorry for my broken English... still learning
