    Radeon 6670 HDMI Output Stops Working After Driver Upgrade

    busterness

      I have a Radeon 6670 in a home-made gaming system.  I have been successfully using a dual monitor system with a small Dell 15" connected to the card's VGA port, and a large Olevia 35" TV connected to the HDMI port.   Worked perfectly until today when I responded to AMD's notification that I needed to upgrade my driver. and install Catalyst.  Once installed, the HDMI port is totally dead.  I've switched monitors and tested the cable on another TV, and both are fine.  Have verified the source on the TV is HDMI.  All I get is "No Signal" on the large monitor.  Tried rolling back the video driver, as well.  No help.  Any ideas?

       

      Thanks!
