    Here are some sites that should help you understand.....

    Any resolution source you play right up to 1080P will work on your LCD TV but it will downscale or convert to 720P. So if you plug in a 1080P blue ray player and play a 1080p disc via HDMI into your LCD it will display it at 720P. Yes it is normal for this to happen.

    If you have a DVD player that 'upscales' or converts to 1080i your player basically takes the normal dvd picture (576i or P if the player is a progressive scan player) and a chip inside the player simply multiplies the number of lines and pixels up to 1080i. Your screen will then downscale this image to 720P as that is the maximum resolution it can handle. The picture will be good, although some upscaling dvd players are better than others and it all depends on the chip(s) inside the player as well as the quality of the TV and how well it converts down.

    I hope this makes more sense and answers your questions
