HDMI vs DVI

by oneCNETuser / August 9, 2009 10:34 AM PDT

Hey ppl, I love the apple macbooks, and learnt that they support only DVI whereas the pc laptops support HDMI video output. Is having HDMI give higher quality picture when outputted to a tv or are the two formats (if that is the correct word, i`m not technical but i love learning about technology) pretty much the same. Also, someone told me that i need a DVI-to-HDMI adapter in order for sound to be outputted to the tv, but i thought that was what the av cables were for (the red, white and yellow), i ma not know what i am talking about, so please ppl help!! Thx, Happy

DVI and HDMI, as far as video goes, should be the same quality (they are actually the exact same signals, just a different connector). DVI does not support audio (just video), so you will need separate audio cables (either AV cables like you were mentioning, or optical out).
Because the connector is different, you will need to get a DVI to HDMI adapter.

They're the same thing

They're the same thing. HDMI is just DVI + toslink in one cable, and some completely pointless encryption garbage tossed in to complicate things needlessly... But that's Hollywood for you.

So long as you don't need audio, DVI will give you the exact same picture quality as HDMI, and so long as you don't need surround sound audio you can just get a 3.5mm to composite audio adapter cable for sound. Sure, it's not as tidy as the all-in-one solution of HDMI, but it will work just as well for non-surround sound audio. I forget if the MacBooks have an optical (toslink) audio output or not, but that would take care of the surround sound audio if they do.

And you should maybe check a bit closer. There are three kinds of DVI, and a lot of video card makers use one that normally can do either analog or digital video, and use the extra pins to transmit the audio portion for HDMI via a special adapter. I can't say for certain of the MacBooks do this, but I'd suspect the MacBook Pro probably would. But there has to be some way for the audio to be routed to that port, otherwise a DVI to HDMI adapter won't do you any good.

Check Apple's accessories for a DVI to HDMI adapter and see if it mentions both supported models AND whether or not it carries audio as well. And if in doubt, call up Apple's sales people and ask them. They overcharge like you wouldn't believe for that stuff, so the least they can do is track down the answer to your question.

Unlike the differences between HDMI and component HDMI vs DVI is more of the same. The only difference is the connection type and the fact that DVI can't carry audio.
