Okay say if I get the new sapphire hd 4870 and I use the s-video to component (they call it the hdtv cable) And I hook it to compoent 1 on my hdtv it will not produce sound because it is only the three video cables, BUT if I then get a 3.5 mm to RCA (Red & White for sound) and hook it up to the 3.5 mm on my mobo then I should be able to then get sound from my computer to my tv right?

And also will the picture coming from the s-video to component be as good as normal component, dvi, or hdmi?

I believe that in theory, your setup should work.

I don't think that the video or sound quality will be as good as if you use a dvi or dvi to hdmi converter and connect that to your tv.
Also, if you mother board has an optical output, that will be your best option for sound quality.

Now dont' quote me on this, but I believe that if you connect the dvi to hdmi converter to your video card, you would be able to get both video and sound to your tv.

Yes, the sound will work the way you propose.

DVI does not carry any audio, so it can't funnel audio through to an HDMI adapter.

You will not notice any difference in the video quality if all the components work as they should.

Then I stand corrected on the dvi to hdmi audio statement.

My hd4870 and hd4850 in the girlfriends case put sound onto our panasonic viera 42" plasm tv as well as video over the hdmi-dvi converter, full dolby sound pass through, easiest way, but not all hdmi-dvi adapters are equal, sapphire cards come with the correct adapter and other than that I am yet still to find one in shops that will work

Yes it will work, but you might end up with slight audio synch problems, but it's a hit/miss issue with that, and likely not terrible if even noticeable.

It's not S-Video it's a 7-8 pin HD Jack that caries the SV and Component information through the same connection, but it's Component out, or as you call it 'normal component' out.

Anywhoo, it won't likely be as good as a DVI or HDMI connection, only because of the nature of the singaling (D-A-A-D), but it might also be 99.44% as good depending on how well your TV handles the signal provided (where it's 1080i or 720P, etc).

DVI and HDMI have the advantage of being less susceptible to corruption and also being better handled by most HDTVs due to the digital nature and easier mapping. If you know what you're doing you can make both look close to similar with a little or a lot of work depending on the help from the Graphics card MFR and drivers/apps.

DB-15/VGA or DVI or HDMI are usually just easier to setup and get working, and on some TVs you are just limited by your inputs and how the TV handles them.

Yes it does & can , and you should really introduce yourself to the ATi HD2K, 3K or 4K series (like the HD4870 the OP mentioned) if you were unaware of that ! [:thegreatgrapeape:2]

Even some Geforce cards allow you to pass audion along the DVI and through an adapter, unlike the ATi HD series cards usually the Geforces have SPDIF inputs to feed back in the audio to the card, while the ATi cards use internal circuitry to pass-through the audio information (which is not limited to SPDIF formats either).

Then I was correct. Next time I will stand on what I know...

To the OP, the easiest thing to do is see if the dvi to hdmi converter came with your card. If it did, get a hdmi cable and connect that to your tv. That should be the easiest way to get the best quality video from your computer to your tv.

Also be sure to download the latest 9.9 Catalyst drivers, it makes HDMI detection at TV instead of DVI easier, and gives you better tweaking option straight out of the gate.
