Hello all, This is something that has been bugging me for some time. Maybe someone out there can explain it to me. I have a 46" Widescreen Hitachi HDTV. It's screen resolution is 1080 vertical lines of resolution and 720 horizontal lines. But I also noticed that a 55" TV has the exact same amount of resolution. How can this be? If the screen size gets bigger, does this not mean that there should be a relative increase in the amount of vertical lines of resolution? The only thing I can think of that makes sense is that the physical width of the resolution lines are wider in a bigger set, than in a smaller set. Again, would this not mean that the picture quality gets degraded the larger you get because the lines of resolution are not as fine as a smaller set? Someone out there please explain this to me.
