    Only one monitor works at a time


    I just built my first pc, and I connect both monitors but only the first monitor connected displays anything and the other will just go idling to sleep. I updated the display driver I've tried to detect other monitors but nothing has seemed to work for me. Please help me

    :)

    Overclocking / Undervolting guide for Vega 56 or 64?

    Here's a quick laundry list:

    List of software to use for overclocking and testing
    Examples:
    Wattman (and how to find and use it, like an overview, including profiles)
    Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
    How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

    Step-by step overclocking in Wattman
    Fan speeds
    Power limit
    Temp limit
    Voltages
    Core speeds
    Memory speeds

  3. Windows 10 Update - Now my dual monitors do not work

    Hi,





    One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:



    • Which Windows 10 build are you using?
    • Have you already tried performing the troubleshooting steps suggested by
      Mauro Cavallin on June 16, 2017?
    • Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
    • What troubleshooting steps have you done so far?


    We will be waiting for your response.
