Do to the fact that LCD's are progressive scan by nature does it really matter to have a True HD (1080P) LCD? Wouldn't a LCD with a 1080i rating naturally convert the signal to progressive. How much of a difference would there be in viewing and up-converted 1080i picture and a true HD 1080p signal. I know there is a major difference between 480i and 480p so I was wondering if the difference in the 1080 signals are the same? From what I hear up-converted signals lose some quality. Thanks in advance for any help.
