I'm having issues with my HP w2007 monitor just constantly changing colors as soon as I plug in the power cord? I've tried to use use both the vga and dvi connectors to see if it comes out of that cycle to display what's on the screen, as the desktop is powered on. I have 4 buttons on the monitor itself "select/auto, menu, - and the + sign. I've tried hitting all of them, nothing happens. I've used another working power cord, vga, dvi cords all that work but the same problem. So I know it's with the monitor. Any ideas? refresh is 60 on windows 7 ultimate. Any help would be appreciated. Not sure if I just need a new monitor at this point or what?
