Hi,

I have AMD FirePro 2460 video card with 4 mini dp outputs & it came with 4 mini display port to DVI pigtail converters.

I have been using Four Dell U2412M High resolution monitors ( 1920x1200 )with it.

Now one of the mini DP to DVI converter doesn't works so I have been searching for it & came across similar converters but they all say it is for Apple Cinema Display, to a Mac Pro (2009), Mac mini (2009), iMac (2009), MacBook, MacBook Pro, and MacBook Air etc.

It looks almost identical to mine except the color, which is white & mine is Black.

I am also not sure if mine is an active conveter or not. Apple's isn't.

Here is what Apple's looks like :

So would Apple's adapter work in my Video Card ?

Thanks

What you need is a mini-DisplayPort to DVI-D active adapter. Single-link DVI-D is good for up to 1920x1200 @60Hz.

If you're running above 1920x1200 @60Hz, you'll need dual-link DVI-D.

You probably want to avoid the Apple cables because they are passive adapters.

First I use only 1920x1200 resolution.

Second, how do I know if mine is active ?

Active ones are very expensive & my Viddeo card is a $ 220.00 card that came with 4 of this adapters. So 4 active adapters themselves will cost over $ 100.00

Mine does play Video & sound if that is any indication of what kind do I have ?

Hi Many Thanks.

I did more research & found mine to be passive but I am using only 1920x1200, it works fine.

For information to others I found this useful too.
