DVI issues

[The Sumerian]

Hi,

I wasn't sure what category to put this under but I have a GeForce FX 5200 graphics card with 64 MB VRAM. It has a DVI port which is hooked up to my Cinema display and there is a second port that looks similar to the DVI but it has more pin. It seems to have 30 pins instead of the 24 pins of the DVI and the port is a bit longer. What kind of port is this? I was hoping to hook up a second monitor but I'm not really sure what cable I want to get. I own an LCD screen with HDMI? Is there a cable has whatever this mystery port is with HDMI on the other end? I assume this thing is a digital port. Does anyone recognize this port by my description? A bit longer than normal DVI and 30 pin?

Maybe? M1 (also called EVC, or P&D)

Never heard of that M1 connector before!

Me neither! Just Googled "30Pin DVI"

That looks to be right! Thanks a bunch, found an m1 to hdmi cable for it too!
