  1. Second monitor not waking up


    Hi,


    I'm running 2 HP monitors, through DP connection, on an HP Elitedesk 800 G4, W10P 1909. This is a clean install with all updates applied. When the screens go to sleep, the secondary screen does not wake up automatically. When i go into display settings -> Multiple Displays, i can select "extend" from the drop down and after doing that 2 or times the secondary display comes on. This makes me think there's no issues with the DP cables themselves, I've also tried swapping DP ports but that doesn't make a difference. I've rolled back the driver for the Intel UHD 630 but it's not helping either.


    At this point it's just an annoyance factor and workable as long as i'm working on it and don't let them go to sleep for to long.


    Any help would be appreciated

    :)

  2. Second monitor screen resolution problem

    Hi,

    For us to properly isolate the issue with your second monitor screen resolution, we would like to know the following:


    • Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?

    • When did the issue first begin?

    • To make sure that we have not missed on anything, what troubleshooting steps have you done so far?

    In the meantime, we suggest that you try resetting your monitor settings, and check if the issue still persists. You may refer to your monitor on how to reset it.

    We look forward to your response.

  3. Issues while installing a second monitor in Windows 10

    Really? I get a canned answer and nothing else? I posted that I had tried everything that I could find posted online. I did read the post that Andre suggested multiple times prior to posting this request for help. None of it helped.

    My computer does not recognize that there is a second monitor is plugged in. The small step of changing the settings so I can put stuff on the second monitor ISN'T the issue. I am not that dumb. in the device manager there is only the single monitor listed
    at one point there was a unknown device listed but my computer did not know if it was a monitor or a printer.

    There has to be someone out there that knows how to fix this

    Please Help

    issue with second monitor

    Hi,

    Thank you for posting your query in Microsoft Community.

    I understand the inconvenience caused. I will be glad to assist you with this.

    I would suggest you to download the display driver from the manufacturer's website. If there are no driver for windows 10, download the latest driver and install it in compatibility mode by following the steps below:

    After you have downloaded the driver:



    a) Right-click on the setup file of the driver and select "Properties".

    b) Select "Compatibility" Tab.

    c) Place a check mark next to "Run this program in Compatibility mode" and select the

    appropriate operating system from the drop down list.

    d) Let the driver install and then check the functionality

    I would also suggest you to refer to the link below for steps to set up dual monitor in your system.

    Connect a second monitor or projector (Applies to windows 10)

    You can also refer to the suggestion by Karthik from this link
    for more information.

    Hope this helps. Do let us know if you need further assistance. We will be glad to help.
