I just need something clarifying for me if you wouldn't mind. I have a Pioneer PDP434HDE and a DV-868AVi DVD player which are connected via the HDMI socket. I'm a little confused as to how this player scales the picture if I'm honest. Please correct me if I'm wrong but the Panel has a maximum resolution of 1024 x 768. So, on this basis is it fair to suggest that insofar as HDTV is concerned I should be able to display video at what is refered to as 720p. I believe this number refers to the vertical no of lines displayed. This makes sense as when I set the DVD player to 720p I get the two black bands at the top and bottom of the screen. What I'm confused about is that last night I was messing with the settings. The DVD manual states that if I select a HDMI screen setting that the panel cannot accept the panel will just be blank and no picture will be shown. This is true having experienced this on a few occasions, however, last night I set the DVD player's HDMI output to 1080i. When I played the DVD (the Incredibles) it played fine and the Panel reported the picture as being played in 1080i mode. How is this possible if my Maximum resolution is 768 lines. Is it that the 1080i is interlaced and really only showing 540 lines at any one time? This kind of makes sense but I couldn't notice a difference between 720p and 1080i if I'm honest. One would expect thaqt if my assumption regarding the 1080i is correct, this in theory should not be as good a picture as the 720p. Does any of this make sense? Still confused! Cheers all.
