Ah, now I see your argument. Just because we can't discern individual pixels doesn't mean the overall picture can't/won't look better at 1080p vs 720p, even at a great distance. For instance. Set up a computer at 720p, and then another at 1080p. Even on the desktop, the difference is obvious.
"Can you see 120hz, too? *giggles*
Just screwin' with ya."
Maybe not 120hz, but I don't think anyone here will argue if I say I can tell the difference between 30fps and 60fps. Depending on the source, I can tell the difference between 60fps and 75 fps. You probably can too. Try messing with your monitors refresh rates and see if you can notice a difference between 60 and 75 hz.
120hz TV's are a step toward different technology that can utilise 120hz. Technolgies like full frame stereoscopic displays (on a single screen).
Witty signature here...
Wii: 14 million by January I sold myself short
360: 13 million by January I sold microsoft short, but not as bad as Nintendo.
PS3: 6 million by January. If it approaches 8 mil i'll eat crow Mnn Crow is yummy.
With these results, I've determined that I suck at long term predictions, and will not long term predict anything ever again. Thus spaketh Crono.
