    Jobs showed the 3GS next to the iPhone 4 and was demoing the improved screen on the iPhone 4. He was showing the video output via a cable from both devices, and not a camera above each phone.

    How is this demoing the screen and not the video output? Would you need a camera above both to show differences in the screen?

    My guess is that they had two projectors with an iPhone connected to each.

    That wouldn't show the pixels though, my bet is that It was pre rendered video I don't know how else they could do it.

    Jobs said during the Keynote that they had to use special projectors for it.

    He doesnt mean this, its good a point however i think the demo was more about the resolution, which obviously could be displayed rather than the actual screen, therefore a video feed from the phone was fine.

    I'm pretty sure it's special software that he has on his demo iPhone's that allows him to output the screen captures through the dock and no, it's not available on any of the phone's we have.

    The projected images compared the relative resolutions of the two screens, obviously not the actual screens themselves. It did not show, for instance, contrast ratio, brightness, or the effects of IPS on the way the phone actually looks.

    Wrong. The projectors projected pixel for pixel.

    That is true, he did say pixel for pixel.
