I have a new Dimension E521 purchased in Feb of 2007. When the computer goes into the sleep mode and I try to start it ,I get this message and have to reboot  "1:Analog Input cannot Display this Video Mode  Optimum Resolution 1680x1050 60 HZ".  My monator instructions say to set at 1680x1050.  If I go down in resoluton the screen looks diferent.
Can anyont help me!
