I just got a Panasonic BD-80 player today. I have a Panasonic L-300U LCD
projector, so I didn't anticipate any compatability problems beyond the
physical. That is, the projector does not have an HDMI input. It has a
DVI-D input. I guess when they made it, that's where they thought the
industry would go. I got the projector back in... 2002 or 2003. Anyway,
I bought a cable that would connect HDMI to DVI-D and plugged everything
in. According to the projector specs, it should be able to handle up to 1080i.
No picture. So I hooked up the component video cables that I had been
using for the Sony DVD player that I used until today, and the picture came
through the components just fine. When I went into the setup menu and set
the component output to 1080i, there was an immediate and obvious change
in the resolution of the image. But my understanding was that the tech was
deliberately hobbled to prevent hi-def signals from going out over the
So I tried playing the one Blu-Ray disc I have so far: Dark City. When I
examined a particular scene (a close-up of a watch dial) the writing on
the watch face as well as the wrinkles on the person's hand were notably
clearer when the component out is set to 1080i as opposed to 480p. The
real revelation was when I put the old 1999 DVD of Dark City into another
DVD player (a Sampo, just for reference). It looked washed out and blurry
in comparison to either image on the blu-ray.
So I am very confused. Did I just waste the money on an HDMI cable?
Or are there untold riches of further blu-ray goodness that I'm not yet
seeing because I'm watching over the regular component video? Any
suggestions as to how I can get the projector and the player to talk to
each other over the HDMI/DVI cable? Obviously, I have set the HDMI
output to "on", and I tried several different output formats, from "Auto"
to "480p" to "1080i". I kept all the special settings like 24p off. Still
nothing comes through the DVI port. I know the port works because I
occasionally hook my computer up to it, and it can talk to computers
So why am I getting nothing from the blu ray? I suppose the cable could
be bad; I could take a voltmeter to it and make sure the pins are connecting
properly, but I have to think this is more likely to be a handshake problem
then a cable problem. The cable was definitely firmly seated. Audio came
through the optical port to my amplifier just fine (no HDMI on the amp).
I have not yet tried playing the 1999 DVD on the blu-ray player; I'll try
that tomorrow, just for comparison. I don't expect anyone here to know
the details of the projector, but if you know the BD-80 well, do you know if
it's really sending a 1080i signal down the components, or is it just that the
rendering of the 2009 blu-ray disc is so much better than the 1999 DVD that
even at 480p it looks much better. If that's the case, why did it look even
better when I manually set the component out to 1080i? And if it *does*
send a 1080i signal down the component lines, why does the manual say
that it won't???? Or does the Dark City disc not have the copy-protect
signal activated? That seems unlikely.
