If you do get a HDMI<-->DVI converter, don't get one with a male HDMI plug unless it's a cable. I got one of these converters to then plug a normal DVI connector into it, and the weight of the thing contorted the connector enough to do some interesting things, first droping green and blue, then going to a digital static screen. My low tech solution was to stack some legos below the converter, holding it in straight.

HDMI is a nice and simple connector, but it lacks screws or any heft to keep it in place well.
