I actually called Apple and asked about it. They were quite clear on that there was no difference, the screens are the same.jkandell said:I noticed this too, in a few ways. Colors better on 20", contrast greater, and text and pictures scroll smoother too (they flash on/off when scrolling the 17").
My question is why there is a difference. The graphics card is the same; the RAM is the same, the pixel pitch is the same. So from whence the difference?
