I thought this cord was a DVI Female? http://vvware.com/cables/product_images/A0084_000-HDMI-...
But then when I got a Male DVI to VGA adapter, it doesnt connect, there are pins that block it from connecting. Heres the adapter I Got: http://www.mcmelectronics.com/content/productimages/s4/24-9350.jpg It has little pins next to the flat blade part, which prevents it from connecting to the first image?

What is this?

Thanks

That VGA to DVI adapter converts VGA to DVI-I (integrated), which offers backwards compatibility for analog devices. Those four pins surrounding the flat blade are part of the DVI-I pin out. The DVI cord you have is a DVI-D (digital) cable, and is incompatible with DVI-I as it lacks the four analog pins that DVI-I has. You may just have to buy a DVI-I cable and use that instead of the DVI-D cable you bought. What are you using this adaptper/cable combination for?

Damn it, that sucks, now I have to return this and re order. I was trying to connect my VGA monitor to my Graphics card, which has display ports on it. I have a Display port to DVI-D cord, then I was gonna use a DVI-D to VGA adapter so i coould connect the monitor, you see? or is that confusing or what

Hmmm, so we have a video card with Display Port connected to a Display Port to DVI adapter connected to a DVI to VGA adapter connected to a VGA cable connected to a monitor. I'm not sure if daisy chaining adapters together like that will work well. You may have to go with a Display port to VGA dongle adapter like this for your setup to work correctly. What video card and monitor setup are you using?

Im using a Sapphire 5870 eyefinity edition edition GPU, it has 6 MINI display ports, and came with a Mini display port to DVI adpater, so I bought a DVI to VGA adapter to connect to that adapter, you see? I would love to get something like the one you sent me on that link, but its way to expensive, I think ill just order a DVI-D to vga adapter its only $4....

I've seen other display port to vga adapters similar to that one for about $25-$30, but that's still a little pricey. Hopefully that other adapter works for you and it doesn't come to that. :)

As was pointed out in a different thread, DMI is a digital only interface. You can DMI to DVI pretty easy, but DMI to VGA is hard because VGA is an analog interface. You'll need an active (read as expensive) adapter if you want to do this. There is no analog in DMI for the VGA to use. You'll need something to convert it.

What is DMI, do you mean HDMI? And also, so are you saying I can not convert Mini display port from my GPU to VGA on my monitor? it wont work?

Yes, I usually drop the H. I forgot you were using mini DP, but the point is the same. I don't think DP has any form of analog for your VGA to pick up, so an active adapter will be needed. It works with DVI because there is DVI A/D/I. Only if you had a straight DVI-D would it not work.

So keeping the current DV-i Adapter i bought, but then also buying a DVI-i cord to replace the DVI-D cord would have worked?

This stuff is so confusing, I mean I get it, Its just lame that theres all these rules and models, I wonder why they sell it if you need an expensive adapter, Oh well, it will arrive in one day and I will learn my lesson if it doesnt work

I'm not sure what "current DV-i Adapter" you bought. You will need an active adapter in there at some point. Something to convert the digital DP signal to analog.

Odd. I wonder why they would make such a thing if it won't work. Perhaps I'm missing something. As I understand things the four pins normally found around that "blade" part of the DVI plug carry the analog info needed for a VGA signal. Why make a DVI-d to VGA adapter if it won't work? I find this part confusing. Let me know how it turns out.

hey wait, look at the description of it! Does this mean it will work? "25pin (24+1) DVI-D male port 15pin VGA female port Color: Black High quality plated pin less signal loss For Digital signal to Analog signal only"

Again, I don't see how. Your bolded statement is simply another way of saying DVI-D to VGA. Its the same thing.

I know, i thought that the bold part means their saying that it DOES work for DVI-D to VGA??

dvi to vga adapters work fine. i didnt know the extra 4 pins have to do with analog, i figured they were just a different version...but those dvi to vga adapters have always worked fine for me, ive never needed an active converter

Are you serious? You sure? So I can connect a Mini display port to DVI-D cord to a DVI-D to VGA Adapter? and it works? This one right here: http://www.newegg.com/Product/Product.aspx?Item=N82E168... ???

So you have used an actual DVI-D to VGA adapter, that exact type? I want to be certain before ordering this again?

oh well then that wont work, that is DVI-I, So how about this, a Mini display port TO vga cord? that should work

Do they make such a beast? If they make that cord, then perhaps DP does have an analog signal as well. I thought it was digital only.
