DVI to HDMI adapter

I've got a m570-ru with the DVI-I port on the back. I want to hook it up to my LCD via hdmi. I know I need to get a DVI male to HDMI female adapter. What I'm wondering is what is the difference between the 24+1 pin and 24+5 pin DVI plugs? From what I can find it looks like the extra pins are for analog colors.

Would either one work for me? Here are pics of each.

 

Actually, all you need is an 18+1, but either will work fine because the extra pins will simply be unused. Of course, I would strongly recommend an actual DVI(female) to HDMI(male) cable, and forgo the adapter because one: it's one less connection to slow down the video feed, two: you only have to pay for a (high quality) cable and three: ten-cent adapters are inherently low-quality and suck.

 

dude it's digital signal, zeros and ones, if the signal goes through it goes through 100% if it doesnt you get nothing. there's no such thing as quality with digital signals... the only thing that can happen is that if the signal is really bad it'll drop now and then

buy the cheap adapters and cables at monoprice.com, all these high quality cables are rip-offs. you should only need high quality cables (also available for less at monoprice.com) if you have a long distance to cover or you're working in a harsh environment where you can expect a lot of wear

 

I have personally bought one of the cheap adapters on Amazon and it worked GREAT unit it BROKE (i.e. just plain stopped working after a month). It is true that Monster Cable and the like are huge ripoffs because digital is digital, but buying cheap will always be exactly that, buying cheap.

 

well you pretty much nailed it... for digital signals cheap works great until it breaks.

the more you have to plug/unplug often the faster it'll break. if you never have to touch your cable setup the cheap hong kong ebay stuff will do just fine... but if you want more durability i would recommend buying the premium cables from monoprice.com instead of the major rip-off brands. you'll get the same quality for a fraction of the price

 

Yeah, I know a paid a little more getting the $24 Belkin cable (I linked to above) vs the $10 generic ones, but it has lasted countless connect/disconnects and also comes with a limited lifetime warranty. Also, I don't have to worry about a stupid adapter.
