  1. Why is my third monitor greyed out and not working?


    Hi, I have a Windows 10 laptop HP Zenbook Studio G5. Via 2 Satechi adapters USB-C I have 2 DELL monitors connected. Both monitors work completely fine. However, when I connect both, only 1 of them will work. If I disconnect the working one, the other one then starts to work. I just cant seem to get both working at the same time. When all are connected, the display settings recognises my 3rd screen, but its greyed out see below. Please help me fix this! CheersRyan

    2560x1440 IPS 27" LED Monitor on the Cheap!

    With IPS panels they always seem to list ms in Black to white (or black to black) TN panels they use grey to grey. This particular monitor lists it as 6ms. That would be 2ms grey to grey. *Smile Why is my third monitor greyed out and not working? :) I'm currently using a 5ms g to g monitor.

    Hi,

    Thank you for writing to Microsoft Community Forums.

    I understand how it could be when the feature doesn’t work as it is supposed to. We will look into this. Please reply to the following questions:

    • Are you facing the similar issue when making the laptop monitor as the Primary monitor?
    • What is model number of your laptop?

    In the meantime, I suggest you to try updating the display drivers and check if that helps. Please follow the steps from the article

    Update drivers in Windows 10
    to update the graphics driver.

    Also, I suggest you to try removing the hidden monitor drivers and check if that makes a difference. Please follow the steps mentioned below:

    1. Press and hold the Windows + X key on the keyboard.
    2. Select Device manager.
    3. Click View tab.
    4. Select Show hidden devices.
    5. Expand Monitors and remove all the greyed out devices. To remove the greyed out devices, right click on the device and select
      uninstall.
    6. Restart your computer.

    Hope it helps.

    Please reply with the status of the issue, we will be glad to help you further.

    Why is my third monitor greyed out and not working?

    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
