I got a free computer from my work. It was completely erased, nothing on it. Bought the OS 10 and I am trying to install it but I get stopped by a message about unsupported video configuration. The model is optiplex 990. This is the message I get: " this computer has an add-in graphics card, but the monitor cable is not lugged into the integrated video connector. To attach the monitor cable to the add-in graphics cards:
Shut down computer
Plug monitor cable into add in graphics card connector ( this may require a video adapter or video adapter cable
Turn on the computer.
I have all cables, only one monitor, what is the issue here? Can anyone help?
Remove any cards from the slots its LFH and you dont have the connector.
You CANNOT have a video card in the X16 slot and use the onboard vga connector.
You cannot use the Built onto the system VGA connector when there is a card in the X16 Video slot.
