The bug wouldn'taffect VGA+DVI  as this would be 2 digital outputs.
The HD 6450 only support analog output on the VGA and only Digital on the DVI/HDMI.
I wanted to use to monitors and wanted to use one of my existing analog monitors and my new HDMI.

The VGA monitor will not work plugged into a VGA->DVI convertor as the
DVI doesn't ouput anything other than a Digital signal.

Check Hardware specs on card to see how this is achieved:  2 sepereated
display loops for analog and digital.
