I want to use 2 LCD Monitors with my PC. Both have VGA and DVI Ports.
I alredy use one Monitor over a VGA-Adapter on the first slot of the Radeon HD.
Now i want to plug in the second Monitor with a DVI-Cable and on the DVI-Slot of the Monitor.
When i plug in the second Monitor my main Monitor goes black and the second one doesn't get any signal.
I have searched in the Control-Center of the Radeon-HD but found nothing tha seemed helpful to me.
