I normally play my PS3 in 720p because my TV is 1366 x 768.

Today I used it on a standard def TV and when I took it back upstairs to my HDTV it automatically chose 1080p as the resolution. I was about to change it back when I realised that the image was slightly sharper, it was only slightly but the biggest difference was my avatar. My avatar of Nathan Drake looked so much sharper in 1080p, the quality of the avatar in 720p was pretty poor.

Is it just me? Is there some sort of glitch with my Avatar? What the hell is going on?
