Yes, I switched cables. Same thing. Yes, I tried the monitor by itself. I am now using it as a VGA device - same thing. Except it doesn't know the name of the device and it doesn't allow the proper resolution.. I guess it doesn't matter. I just use it for viewing databases, and having all the dialogs and stuff from visual studio on there to clear up my main monitor. I think it'd be better just to have a big 32" LCD or something
