Thanks Stuart, It's a decent monitor, I think it was about $800 many years ago (Dell 2405 FPW I just checked). I can't imagine the image being better (except when it needs the downshift/upshift which happens only on startup [whether from sleep, hibernate, shutoff, whatever it is, once I get it sharp is stays that way for the session] --I suppose it's one of those "got used to it" things).
It came with two cables so I might as well invest $11 (shipped) and get the DVI-D adapter. I read the Wiki article on DisplayPort and came out more confused than when I went in. :( Is a passive single-link adapter all I need for my X220 and this display, or do I need something more? (Other's answers imply this is okay). >The DisplayPort signal is not compatible with HDMI or DVI. >Nevertheless, dual-mode ports marked with a DP++ logo can transmit >single-link HDMI and DVI signals through DisplayPort cabling; this >requires passive external adapters which convert to the higher signal >levels used by DVI/HDMI.

Can my (coming) X220 drive a bigger monitor at more than 1920x1200?
