[Kiva]

Hi there

Putting together that computer order for the friend in Kabul. I got her a Mini DVI to VGA adapter. I also want to get her a Mini DVI to DVI adapter so that she can connect to a newer monitor. However, the discussion on the product page about the thing not working (DVI-D vs. DVI-I??) is confusing me. Can somebody explain which DVI adapter to get to maximize the # of DVI monitors she will be able to connect to?
