Summary: Unpacked the new Dell and found I couldn't plug the second monitor into the graphics card. I was used to getting a 2 way pigtail from Dell adapters. For this build I chose a better graphics card. I found out I was on the hook to ensure I had the necessary adapters. Went to Dell.com, found the adapter and placed the order in 2 minutes.
Summary: after using this adpater for less than one year with some minor issues, it failed completely. After being transferred four times Patrick finally explained there was no warranty. So buyer beware, you might want to consider buying this or a simular product with a warranty, or at least a company who wont transfer you for over an hour just to tell you, you dont have a warranty and transfer you to another department thats closed
Summary: I bought this about 6 months ago for an eyefinity setup. Like everyone else said, it would cause a flickering screen that would require a reboot every couple of days. It worked fine 99% of the time. The product is now outdated. There is a new ACTIVE DP adapter available that requires no USB power connection and doesn't suffer from flickering. It is about $25 and works flawlessly from what I've seen. Get that one, save some money and aggravation...
Summary: Been using for past 2 days on a new dell studio XPS 1645 to drive a dell 30" 3007WFPHC at max resolution of 2560x1600 without any problems whatsoever. Actually the picture is crisp, stable and quite amazing.
Summary: Because of a few mixed reviews I tried to confirm this adapter would work with my Precision M4500 laptop before ordering and the support agent insisted that it would only work with the docking station. After receiving the adapter and the M4500 I can confirm that it works just fine on my 30" 2560x1600 HP display with the built-in displayport connector on the laptop - no dock is necessary.
Glitchy, and now appears to have failed completely

Summary: This thing is okay when it works (and it's the only game in town anyway if you're stuck with a nice, large DVI-D monitor and a DisplayPort video card), but the problem is that it rarely works. On average about once a day there would be a problem with the sync/scan (one plane of the display would be shifted, so everything would be ghosted by several hundred pixels) that could only be fixed by switching to a much lower resolution and then back to the native 2560x1600 -...
Summary: Ordered on Wednesday and received 4 days later. The entire process of opening the package and installing adapter/monitor was under 2 minutes and seamless. Plug and Play! I am running a XPS 8100 with the ATI 5770 utilizing the DP port, the HDMI and 1 DVI. A little expensive, but I Highly recommend!
