I'm looking for a DVI to VGA cable. I was just wondering if this was a DVI-I cable. And are DVI-I single link and dual link interchangeable?
(Update) Thanks guys! Wouldn't say it works great... The size difference is throwing me off a bit. But at least it works :)

Single link DVI is able to transfer 1920 x 1080 resolution vs dual link 2048 x 1536.
If your display is more than 1920 x 1080 then you need DualLink.
1920 x 1080 or under you need Signal.
The "-#" at the end are just the types of DVI cable.
Off the top of my head.
is the normal most used one that transfers digital only video.
is send digital and analog video in the same cable.
In the case of DVI to VGA, you want a DVI-A cable. That takes the video from a DVI graphics card to an analog device.

Digital and Analog are carried over the same cable, but in different streams. There are different version of DVI cables that allow one or both of those streams to be transmitted.
DVI-D is digital only even if you have an analog stream available on your DVI connector on your video card. DVI-A is analog only. This will take your analog stream from your DVI connector on your video card and pump it to another device that either has a DVI-A connector on it or to a DVI to VGA adapter. DVI-I is both at the same time. This is regardless of dual link or single link. The link type only applies to the digital signal. Again, you would need a DVI to VGA adapter to plug into a VGA monitor. The digital signal will be terminated at the adapter.
The key here is if your video card supports analog through DVI. Quite a few of them do, but it is becoming more and more common that they don't due to LCD's being digital and CRT monitors are on the way out.
If you are planning on putting a CRT/analog monitor onto a DVI video card, first make sure the video card supports analog over DVI then get a DVI to VGA adapter and plug into that the VGA cable going to the monitor.

Actually, that is a DVI-A adapter. That means it can only carry the analog signal from your computer to a monitor. (DVI-I can carry both analog and digital signals).
DVI single link cable can display a resolution of 1920 x 1200, while a DVI dual link can display a resolution of 2560 x 1600. As long as you don't go over the max resolution, you can use a single link cable instead of a dual link cable.
