You mean the Dell didn't come with a DVI cable? I would have thought it should, my Dell 24" I got a year and a half ago came with both.
I don't know what the 20" panels are like, but my 24" is a lot better with DVI than it was on VGA. Granted I went from a laptop with integrated Intel graphics to a nVidia Quadro which probably helped too.

I will move forward as though all 3 adapters are compatible. Yes, I still operate in the analog video modes because my KVM switch will only switch the old 15-pin DSub type of cable(s). My new Dell 20in WS panel does have the DVI connector, but I do not have a DVI-DVI cable to play with yet................ :) One day soon, I may start a search for KVM switches that use USB (kbd/mouse) and digital video switching. Thank you so much. The Collective does rule!! Happy New Year!!!!
