Just received a U2412M via Amazon. At power-up, all I get from it are various color bands. Eventually they fade away.
When powered w/o any computer connection, just bands, no floating 'no connection detected' message. Can't get the menu button to display anything.
When hooked to the computer, just more and different bands.
So it seems to me to be broken, but I thought I'd pose this question to others before I see about sending it back. See below for picture of what I'm talking about.
