DVI-HDMI cable question on HD 4890

[Darthzin]

So here's the situation,

just got this new LED TV coming home which has HDMI (duh!) port. My GPU is Powercolor HD 4890 wich (from what I've read) support sound over HDMI but has two DVI port. Again from what I've read, converting the signal from DVI to HDMI will let me have both audio and video on my TV has long as I use the right cable. Something about have the right pin on the DVI connector.

Was looking at DVI-HDMI cable over monoprice and no mention if they can carry the sound or not.

I think I need some light here! :)

TIA

gpu should have a mini hdmi port

Your best bet is to buy a dvi-hdmi adapter instead of buying a cable with dvi on one end and hdmi on the other. The adapter sells for about $12-$15. You might get one cheaper if you place a WTB ad in our BST thread.

so, adapter + hdmi cable would work but not dvi- hdmi cable?

You need one of these: http://www.ebay.ca/itm/170730652821?...#ht_4097wt_846

I purchased one off of eBay recently from the same seller and it works great, though shipping takes a while. A regular DVI->HDMI cable will NOT work properly as ATI uses a special pin-out to get audio out of DVI.

Also, if you hook it all up and don't get sound, you might have to go into start>control panel > sound and switch default to hdmi.

Is an audio loop cable required, or is that only for older cards? I'm pretty sure that for my GTX 275, if I use an adapter from DVI to HDMI, I won't get sound unless I use an audio loop cable.

The ATI's have an onboard sound processor to feed the sound over HDMI. No other cables are required.
