I noticed this on Samsungs exellent tutorial site @ http://product.samsung.com/cgi-bin/n...module_6_1.jsp
Quote:
HDMI is a relatively new interface that will eventually replace DVI. Unlike DVI, HDMI will also carry digital audio signals and data, and HDMI connectors can be daisy-chained from one component to another in your TV or home entertainment system
That's news to me -- about the daisychaining - Is that implemented on some devices or is it a "lost" feature - I have a HDMI switch - but daisychaining would be preferable.

A Red/White dual cable is an 'analog stereo pair'. Not digital audio compatible.

I've never seen a daisychainable HDMI setup... no HDMI pass thru outputs. Now, FIREWIRE is daisychainable...

Default Cable question

I posted this over in the Dish Network forum, but perhaps it would have been better here, so I'll post it again. I apologize for the added noise.

I have an 811 and my TV is a Sony KDF42WE655. I have the DN HD package. I am using these cables- Monster Cable Component Video Cable (MV2CV-2M). If I switched to HDMI would I really see improvement in picture puality? And I am under the impression there is no reason to upgrade from component with my DVD player. Is that correct?

And with HDMI I could stop using an additional digital audio cable, as I understand. Would I lose anything on audio quality?

I will admit I notice the better picture from DVD w/hdmi to tv but my cable box w/hdmi to tv seems no different than components from cable box to tv...guy at cable company told that since all cable,albeit digital,is still converted from analog to digital even before getting to your tv since all cable is transmitted into our homes via coaxil,which is simply not a carrier of "TRUE" digital signal,the box itself converts the analog signal to digital,although if this is true,then i guess it could save you one conversion but not really sure....anybody know?

At a Radioshack store I saw a "VGA to DVI converter". Will this convert to DVI-A? And would I be able to connect this type of DVI output to a Digital HDTV

Had a similar problem with my Sony KD34XBR960
Read the MANUAL, & it specifically said, to use input 7, ONLY for HDMI
Perfect!

Default why is video+audio in one connector "better"?

Dumb newbie question: A supposed "advantage" of HDMI is that digital audio is on the same cable with the video. But don't you need to send the video to the display and the audio to the sound system, which are typically separate boxes?
If the signal always needs to be split between boxes, what's the point of a single cable/connector?

Default DVI-I to DVI-D converters

Okay, okay, I know the difference. I thought it would be a simple matter to find a DVI-I to DVI-D converter dongle, like the DVI-I to VGA dongles that come with every video card nowadays.

I understand that the DVI-I is a superset of DVI-D and know to expect that only the digital signals would need to be passed. But all I can find online are custom cables. No converters. Seems like a business opportunity to me. Or am I the only guy with a drawer full of DVI-I cables that are worthless?

That was exactly the question i originally asked myself when the HDMI links launched. if you are a high-end audio craver, the signals will almost always run to seperate components.
I realized that the majority of the market would prefer a single link for convenience though.
My issue with this is that surely there would be a loss of sound quality in a link like this as opposed to a proper seperate AES EBU or high quality Coax link for the audio.
has anyone actually tried to compare the sound in a high-end system over HDMI vs Coax/AES?

Does the HDMI just eliminate the 5 wires or does it really make a difference in picture quality?
