Hi all, hope this is the right forum?!?

I have a Scientific Atlanta 3250HD STB and a Samsung LN-S3251D LCD TV. I am using the upscaling function in the STB to upscale all 480i ---> 480p. And it also upscales all HD to 1080i.
My LCD supports 1080i and 720p. After viewing the HD channels in both formats, the 1080i is much sharper and more accurate as far as colors. When selecting 720p for the HD channels, the image is similar to 480p.
My screen is 1366x768, so I figured 720p would look better when i selected it through the STB since its closer to my native resolution.
Anyone have any suggestions as to why 720 does not appear sharp, and 1080 looks better overall? There is a significant difference. I have cox cable.
