    Computer boots up with only one monitor on


    Whenever I boot up my computer or restart it, only one monitor comes on. I have to physically click on/off the power switch on the other monitor for it to be fixed. Any ideas?

  2. Unable to boot the computer.

    Hi Samid,

    Thank you for posting your query on Microsoft Community.

    Before we proceed, we would require more information to assist you further.


    • What is the make and model of your computer?

    I suggest you check if you are able to boot into Windows Recovery Environment using installation media. Follow the steps provided below and check.

      • Insert the installation USB and boot Windows 10 from it.
      • In the ‘Windows setup’ page select the ‘language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.
      • Click on ‘Repair your computer’ and select ‘Troubleshoot’.
    Check if you are able to boot to this window. If you are unable to boot to this window, I suggest you to contact the manufacturer and check.

    Hope this information is helpful. Reply us with this information to assist you further.

    Thank you.

    Computer boots up with only one monitor on

    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
