so Julio, what you say is Tosh user manual is wrong that 1080i isn't the best resol to get best PQ out of this HM(X) DLP? instead 720p gives you the best overall PQ.
a guy told me what he got when talked to Tosh CS rep. this DLP converts all signals (480i/p, 1080i/p) to 720p. if this is true, then what printed on manual is really wrong.
is there any method can check what the input resol is? 62HM84.

Let me indicate that Toshiba Customer Service did call my house, which I found impressive, but the lady, although very kind, didn't seem to understand the nature of the issue. She offered advise based on the User Manual and also catalog advertising for this and other units, and her answer was that the HDMI input was designed with 1080i as the best signal and even indicated that DLP units upconverted the signals to 1080i if image quality was high.
I told her to take the issue to the next level and also e-mailed again, this time with a shorter version of the issue and including our observations of the Manual. This is their final answer:
Thanks for writing!
The recommendation in the owners manual was an out take from or CRT HD TVs but it does not hold true with the DLPs. DLP TVs have a native output of 720p which would be the best signal to run on those units.

As you can see, many people here was correct indicating there was something wrong with the Manual and that they were like cutting-pasting indications; something that, to say the least, is shameful for a high-tec company.
Also all that said that 720p was the best were correct, at least from the technical and specs point of view. It would be nice if someone could explain definitely why some sources look better at 1080i (better digitalization, better de-interlacing?) Maybe it's just a matter of taste, but probably maintaining the 720p output on the sources will give the best average image quality for all programs.
I admit I was wrong in some of my previous answers, although I still believe that the system does something like a re-size for the 1080i signals; but that's just me.
I hope this message from Toshiba helps everyone here.
