I'm using a Denon 1910 into a Sharp GA4. I can select (using DVI) the normal res progressive as well as 720p and 1080i. However, all my aspect ratios appear to be absolutely normal. The quality is clearly increased within the picture on 720p and the screen is telling me that 720 p is being received. The reason I've asked is that some posts appear to suggest that the aspect ratios are zoomed a little (if that's my understanding) and others say that there is a border. On 1:85:1 the picture fills the screen in the same way. On 2:35:1 the normal borders are present. Can someone please explain?
