An HDMI HDCP question

[music fan SF]

I recently purchased a Samsung LN 3251D 32 inch LCD TV. It's beautiful. I use it for movies, for family photo slide shows (it's connected to a laptop) and for over the air digital TV viewing (I don't have and don't want cable TV)

My current DVD connection is component cables from my old 480i --> Denon 3806 receiver--> Samsung TV, both connections are component. The picture on the TV looks great, with the TV handling all the scaling and deinterlacing.

Here's my question: The Denon 3806 has HDMI, including analog to HDMI conversion. When I try to run HDMI from the receiver to the TV, the TV says 'Not Supported Mode,' which means it detects a signal but won't show it. The TVs HDMI interface supports HDCP (high def copy protection), and the Denon says it supports HDCP as well, but of course the analog video signals in to the receiver don't have these HDCP flags. Does HDCP rule out analog-HDMI conversions?

The TV has two HDMI inputs and I have tried them both, and I have tried the different HDMI out settings on the Denon. Denon is set to do analog to HDMI conversion. The Samsung TV takes 480i inputs over the air and from the component connections, the manual does not say that 480i over HDMI is not supported so I assume that it is supported.

So I'm just wondering: does HDCP mean only pure digital and copy protected sources can be shown over HDMI?

I don't have an HDMI source to use at the moment. I assume that the HDMI interface on the TV works as it is supposed to, since every other aspect of the TV that I can test is perfect.

Any thoughts? Have other folks encountered this problem?

I believe one of your initial assumptions is the one that I would go with as the issue: 480i over HDMI is often not supported by displays.

In looking at the manual for the product, the English page 25 version is the only indication of modes for formats and isn't specific, but it does seem to indicate that HDMI only supports 720p and 1080i. Not even 480p apparently.

Further reading says that PC fomrats are not supported over HDMI at all and must use the VGA connection.

I would bet strongly that this is the issue with your display - but because it is specifically NOT in the manual it can't be confirmed without calling them would be my guess.

Thanks

That seems like a reasonable suggestion. As I said above, I don't have an HDMI source at the moment, and the Samsung manual is not exactly a model of clarity. But if displays generally can't diplay 480i input over HDMI, doesn't that also prevent them from displaying SD digital cable signals over HDMI?

Did you make sure you setup the receiver to input the component and output via HDMI?

Yes - but most cable boxes will upconvert all signals to 720p or 1080i in the setup menus. So, 480i SDTV will be upconverted and will be sent out in a format the TV is happy with.

Yes, of course

Yes, I set the receiver to translate all analog video to HDMI...
