Pros: -works as advertised up to 2560x1600 on my hp z30 display (highest res display I had available to test it on) -says "Dual Link" on it, which is actually nice to help me keep track of it separate from the dozen other DP -> DVI adapters I have

Cons: -Didn't work with an Apple 30" cinema display (the very thing I bought it for). While it did seem to recognize the display as capable of up to 2560x1600 (native) resolution (unlike all my other adapters which only show it as having a max native res of 1280x800), if I specified a resolution above 1280x800, even with this adapter, the display just went dark and wouldn't show anything :-(. And yes, I do know it requires a dual-link cable. Note that the Apple 30" cinema display has the cable built-in. And yes the Display works fine with an nVidia card that has a dual-link dvi ouput in a newer Dell workstation desktop.

Pros: -Very nice to have a single adapter and be able to connect to pretty much anything -Does seem to work with the DVI & VGA ports (didn't test HDMI)

Cons: -I could not get it to drive a 30" display at 2560x1600 as advertised over dual-link dvi. It only recognizes the display when connected through this adapter as being capable of a max (native) resolution of 1920x1200. This would be the typical max for a single-link DVI connection. Yes I was using a dual-link DVI cable. I have another 'Active' DP -> Dual-link DVI adapter that works just fine in this setup. Tried two different laptops, and two different screens, same result.

Overall Review: -If you don't need the high (2K / 4K) resolutions, this thing is great and very handy. I have another one with a mini-DP connector that I keep in my bag with my laptop. However, that one was not advertised to support more than 1920x1200 over DVI/VGA or 1920x1080 over HDMI. -I believe the specs for this device are simply listed incorrectly.
