I have a Radeon HB6450 1GB DDR3 graphics card. My monitor is plugged into the VGA port. I recently purchased a projector (BENQ MW 519) which I plugged into the HDMI port.
When turned on the computer, it went through the bios boot with both the monitor and projector showing the screen(s). After passing the bios, the monitor went black and the projector indicated that it had and HDMI source but displayed nothing.
I want to have the monitor as the primary display (via the VGA output) and use the projector as a secondary (duplicate screen) output on a casual basis.
I presume that what is happening is that the graphics cards is giving the HDMI output primacy and perhaps something with the resolution is preventing either one displaying.
I can not configure this in Catalyst Control Centre / Vision Engine Control Centre as it only sees one monitor when I plug in the VGA monitor and neither screen displays anything when I have both plugged in.
