How to use HDMI & DVI at the same time...

  1. I just built a new PC and installed a Sapphire RADEON HD 6670 1gb DDR5...

    I want to run two monitors (extended) using the DVI and HDMI ports. I just get a black screen on the second monitor??

    Which operating system are you using?
    Do you have an option to extend desktop in Windows display properties?

    If you are using Windows 7 try pressing "Windows Key + P" at the same time. This should bring up a projection menu with 4 options.
