HDMI Adapter Questions.

[Jordan Bruce]

Hello, I'm considering purchasing a new TV for my family and myself but i have a few questions before I do. My first question is that if i purchase a DVI to HDMI adapter to play movies through a PCs Graphics card will i still receive the same quality HD as if i used a normal HDMI to HDMI port.

And my second question is would the audio "go through the HDMI cable" to the TV or will I need to find an alternative way to get the sound from the PC to play through the TV.

Thank you for taking the time to read my post

1. Yes dvi/hdmi no difference for 1080p

2. Audio won't go through DVI. You need to output audio via green speaker out (stereo) or optical port (5.1) on the back of the pc.

Yes, the quality will be exactly the same with the adapter and without it.

Most likely it will go through the cable, although some TVs don't support sound through HDMI.

@i7Baby: While the DVI standard doesn't include audio support, it's very common that DVI ports actually include sound output so that they can pass sound through them if they're used with a DVI to HDMI adapter.

I was looking at the pinout in http/en.wikipedia.org/wiki/Digital_Visual_Interface. Couldn't see any audio

Not in the basic pinout, but when DVI is converted to HDMI, the DVI actually outputs a HDMI signal.
From the same Wikipedia page:

So, DVI-D devices output HDMI signals, many including audio, (examples: ATI 3000-series and NVIDIA GTX 200-series video cards),[9] and some multimedia displays input that HDMI signal, including audio, by using a DVI to HDMI adapter. Exact capabilities vary by video card specifications.

Hmm needs updating - ATI 3000 and GTX 200. Also dvi-i vs dvi-d for audio.
