I've had the above monitor successfully working (via a VGA cable) to a Dell Optiplex 3020 base unit for a year or so. Today I decided to do a gentle internal dusting out inside the base unit, which means disconnecting everything from the pc. After putting it back together, I am left with a problem. When I switch the pc on, it boots up fine and there is output on the screen. When I click power==>sleep, the pc switches down and the monitor goes off. Quite normal and what I have been used to. A single left click on the mouse powers the pc back on again but I am getting nothing on the screen - it remains black. The only way I can then switch off is to hold the power button on for 3 or 4 seconds until the pc shuts down.
I understand something has been upset in the power save mode settings somewhere - as a result of taking the VGA cable out of the back of the pc but I just don't know how to resolve the issue. Can anyone help??
