How can you know the fps or 480p/576p/720p/1080p/1080i by looking at it?

I can tell the frame rate - differentiate even between 50hz and 60hz

But the resolution is tricky - Many Wii games look much better than some PS3 games - really you would have to see a multiplatform game, PS3 on 1 tv and Wii on another
