I have a Dell 3007WFP monitor which features only DualLink DVI-D for video input. The computer I am trying to connect it to only features VGA, DisplayPort, and SingleLink DVI-D (via a docking station). The built-in DisplayPort supports up to my maximum resolution of 2560x1600, meanwhile the VGA and SingleLink DVI-D connections are insufficient.
I found the following device which purports to be capable of converting a DualLink DVI-D signal to DisplayPort. Will this converter indeed work to connect a DualLink DVI-D monitor output to the DisplayPort input on my computer at maximum resolution?

– Wuffers – 2011-05-13T23:02:55.6635@MarkSzymanski Not a shopping question. I'm asking if it would do what I need. I don't want to buy it if it won't work. – Nathan Taylor – 2011-05-13T23:05:43.587
3@MarkSzymanski this isn't a shopping recommendation per se, he's asking if the given product will work for his computer. – nhinkle – 2011-05-13T23:05:44.303
Agreed, this is a functionality question - "Is this the right sort of device to do this with" not "Which one should I buy", which isn't really a shopping recommendation, anymore than saying "What do I need to buy to program EEPROM chips with?" is a shopping recommendation. ("Which programmer should I buy?" would be one, though.) – Shinrai – 2011-05-13T23:09:25.953
