    945GM Express Chipset - Dual Monitor Recognized, but Black

    3wide

      I've been using Dual Monitor with no problems on this system for 2 years with zero problems. It is an HP dv6365US wit the 945GM Express Chipset.

       

      It was working fine last weekend. I was travelling for 4 days not using the dual monitor, then, when I returned, and plugged the second monitor back in, it didn't show any graphic.

       

       

      The monitor is 100% recognized. I can move windows to it, Change its resolution, set it as main/extended monitor  - do Anything I want to it. However, the power LED just blinks green and the screen is completely black. If I unplug the VGA cable, the monitor change states saying it is not receiving a signal.

       

       

      The monitor shows black at startup as well.

       

      It is not a monitor issue, I plugged in another monitor and the same thing happened.

       

      I have already tried restoring factory drivers, then, reinstalling updated drivers, nothing worked there either.

       

      I've done power offs and let them set and nothing.

       

       

      Any other ideas?
