DVI-I - Single Link vs Dual Link

How do I know if my Dell Latitude E6420 has dual link DVI? It has a VGA output but the docking station has two DVI outputs?

Is there a VGA to Dual Link DVI adapter?

Is Dual Link DVI a computer spec or a cable feature?

It's a function of the port (and by extension, the video adapter) itself. The only way to be 100% sure is to look up the exact specs on the hardware in question. (Dual-link does have more pins but some single-link ports have the holes for those pins, just not connected to anything, so visual inspection isn't sufficient.) –  Shinrai Jan 10 '12 at 15:36

The product you are looking at appears to be Dell part number 430-3113. Although it is not clear, it appears that this docking port offers only a single-link DVI connector. The higher end docking port, Dell part number 430-3114, specifically lists that it supports 2560x1600 via the display ports. This implies that the included DVI connectors are still single-link, but at least you now would be able to run the higher resolution through a display port connection, assuming your monitor can support that.

A Dell Sales Rep said they're Dual Link. I'm not sure if he's a reliable source though... –  Bruno Jan 10 '12 at 16:13
