    Assistance Connecting Three Monitors

    adamth

      Hello,

       

      I am trying to get three identical monitors to work. Usually I use one monitor, now I have a total of three.  I cannot get all to work at the same time.

       

      From what I can conclude, and am asking here, is that for all three to work I need:

       

      HDMI output ---> to HDMI input on monitor

      DVI output ----> to HDMI Passive Adaptor ---> to HDMI input on monitor

      DP output ---> to HDMI Active Adaptor ---> to HDMI input on monitor

       

      Currently I do not have the Active Adaptor and I am assuming that is what I need.  I would like to know if that is correct before I purchase one.

       

      Currently I have this arrangement and can only get a maximum of two monitors to work at the same time.

       

      HDMI output ---> to HDMI input on monitor

      DVI output ----> to HDMI Passive Adaptor ---> to HDMI input on monitor (I am assuming the adaptor here is Passive, it's just a little one inch female-male adaptor)

      DP output ---> to HDMI Passive Adaptor ---> to HDMI input on monitor

      Details/Troubleshooting History

       

      All monitors are Philips 216V6.  All have been tested independently and work.  All cables have been tested and work.

      I have updated BIOS.

      I have updated graphic card drivers.

      Graphics card is AMD HD Radeon 6800.

      I have Windows 10.  It is up to date.

       

      When the computer is restarted, the middle and right screen display the post screen/BIOS.  Then when the login screen appears only the middle and left screen display picture.

       

      When any monitor is connected, Windows makes that gentle beep/chirping noise.

       

      All monitors appear in device manager.

       

      When I go into AMD's Catalyst Controller, if I go to "Creating and Arranging Desktops," three monitor icons are there. Two of them have "1" and "2".  If I right click the monitor without a number and select Extend, I get a message that says "To extend the desktop, a desktop or display must be disabled."

       

      I hope I have provided enough details.

       

      Thank you!
