DVI vs HDMI

[1Boner]

I have a new system coming in a few days.

From what I've read, there's not any video quality differences between dvi and hdmi.

However if I plug the hdmi into the output for the graphics card will the sound quality be affected?

Does the graphics card get its audio from the computers THX audio or does it have its own lower quality sound on board?

Thanks, Boner

short answer is you need hdmi to play blueray dvds on your computer.

The only difference between DVI and HDMI, is that HDMI has audio.   The picture quality is the same.   But your post is completely incorrect.

Both are digital video signals, and for the most part, both are somewhat compatible with each other (just need a converter). But, as Karaya said, the primary difference is that HDMI can also transmit audio signals, DVI does not.

hmm sorry. always thought you needed hdmi for blueray to play for copyright reasons

The only way to benefit from BD, is to have a BD player and a 1080p TV.   The connection (even Analog) does not matter.   HDMI is simply an excellent way to keep an HT "clean" with fewer wires (connections) and eliminate the spaghetti normally associated with it.

my esteemed collegue has once again cleared the fog from my brain.

Where does the sound originate from if I am using a hdmi cord directly to the graphics card?

Does the graphics card have its own sound processer build in? Or is it somehow connected to the computers on board sound?

Or, would it be better to run dvi from the graphics card and run the sound with simple component cables.

you need to connect the GPU sound in to the mobo SPDIF Out, if your GPU has HDMI you should have been supplied a small cable to do this.

Even if the GPU has an onboard sound chip and he's using HDMI?  Wouldn't it bypass anything onboard then?

That's HDCP

That solely depends on DVI type. DVI-A for example, carries analog signal. DVI-D digital, DVI-I both. DVI-A is rare though...

I used HDMI on my TV and the difference was significant or seemed that way. At least it was from component to HDMI. Not sure about computers.

The GPU has a built-in audio device (some have more than one). Usually the high-definition link passes from the motherboard to the GPU and I think the whole purpose is syncing video and audio so that the display and the display speakers as well as external speakers are all in synch. Otherwise you would probably experience audio lag from monitors to external speakers. So if you want to use just a monitor that has its own speakers then you want DVI or HDMI (either one) and if you want to use the monitor plus external speakers then you will need the HD-S/PDIF connection.

I have never tried to use the monitor audio because it just doesnt seem realistic that it would be high quality.

My 5850 doesn't require an additional cable for sound.  In fact, it doesn't have a plug for an audio cable like you're mentioning above.  Is this something on older cards (older being very relative here...)?

I thought BD wouldn't play on connections that don't support HDCP?  Does DVI support HDCP (like HDMI obviously does)?
