Pros: Worked great out of the box.

Cons: none

Other Thoughts: Mike said if you use these cables other ones won't work. I have the MSI R7850 Twin Frozr 2GD5OC and it works with an HDMI cable to get me 2 displays but the DVI wouldn't work for a 3rd.
I'm trying to get 3 monitors to work. My vid card has 2 of these mini ports, 1 HDMI and 1 DVI.
I'm ordering another one of these. I figure if 1 of these works with the HDMI, maybe 2 will, giving me 3 displays. I'll post another review when the cable arrives.

Pros: Able to display from MIni display port to DVI no problem

Cons: Wasn't able to use 3rd monitor. maybe it isn't an active adapter? more information on this would be great.

DVI plug is massive, normally not a problem.

Other Thoughts: good for 1st or 2nd monitor, no problems, purchased for a 3rd monitor and it didn't want to enable. I feel my tech knowledge is lacking for this. all the same ratio, and size monitor... just didn't want to enable all three. ):

Pros: Works with the AMD Firepro W4100. I like the length of this cable because it avoided having any adapters. Also remember you have to use the same cables on all 4 monitors or the odd cables one doesn't work.

Cons: As with any Mini DisplayPort make sure your cables are supported physically coming out the back of the video card.
