in the last paragraph. The source is only 1080i so that's what you'll see. You'll only achieve a 1080p picture through BluRay or a PS3. They're both 1080p. Not that you would see much of a difference anyway. With a screen size smaller than 50", you're going to see very little of the picture quality that a true 1080p source has to offer. I too have a 46" screen and the only difference I notice between my Up-converting DVD player and BluRay is the color may "Pop" a little more with BluRay, but it has to be a picture with a lot of color in it. Other than that...not much of a difference.
Enjoy your new TV.
I've got a rather stupid question about HDTV and de-interlacing.
I just purchased my first 1080p HDTV. It's an LG 47" LCD model 47LC7DF.
I've set my DirecTV HD-DVR receiver to display at 1080i and assumed, probably incorrectly, that my TV would de-interlace the signal to present it at 1080p. However, when I push the "Enter" button on the remote, it's telling me it's displaying at 1080i not 1080p. Which of course makes some sense because the program is being sent from the receiver at 1080i.
However, shouldn't the TV be de-interlacing the signal and presenting it in 1080p? Or is this not possible and TV programs will be presented in 1080i if that's the resolution I've got the DirecTV receiver set at?
