Does a True HD (1080P) rating really matter?

[RMD68]

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.

if a TV has enough pixels to display a 1080i picture it will have enough to display a 1080p one so i can onlt imagine that the tv's that ONLY do 1080i are downscaling it anywat to a 720 pannel. If that is the case you would NOT notice a difference between 1080i and 1080p. but on a 1080p TV you can see a diference. i was given a demo in the sony style store in millenia mall in FL, they had a 60" true HD 1080p TV hooked up to a BD player and changed the BD players o/p through the other HD settings, 1080i, 720p and 720i, there was a noticable diference between the outputs.

but in the UK anyway prices of true HD 1080p TV's are falling fast, you can walk into a store and pick up a 42" Sony for arround £1600 GBP, with (as the title hints at) a 1920x1080 pannel, or you could pay £200 more and get a Tohsiba 46" HD Ready TV that only has a 1024x768 pannel (yes i did type in the right numbers) and pay more for a tv that actually can not display a high def image
