Can Hdmi Be Converted To Dvi-d Dual Link?

[vizskywalker 0]

I currently have a PS3 that is outputting using HDMI. The HDMI is converted to DVI-D and connected to a Dell 20 inch flat panel. This works nicely, except that I can do a maximum resolution of 780p, and I would like to do 1080p. So I am thinking about upgrading my monitor, and I was thinking, why not go for a 30 inch monitor? But the 30 inch monitor requires DVI-D Dual Link. I was wondering if HDMI could be converted to DVI-D Dual Link or whether I would be wasting my time (and money). The adapter I have has the slots for a Dual Link DVI-D cable, but I don't know if they are actually used, or just available so that a DVI-D Dual Link cable could be connected, since DVI-D Dual Link cables can also carry single link information. Apparently the tech spec for converting between DVI and HDMI is EIA-861 DTV, but I have been unable to find a copy. Any help on this matter would be appreciated.~Viz
