    Second monitor not waking up


    I am new in Ten. Regardless I use daily a remote machine with Windows 10 I just installed it on my own local computer a couple days ago (I had Windows 7 on it before).

    My PC has a dual monitor setup both plugged to the onboard adapters of my Gigabyte mobo. The main monitor is plugged to a DB-25 and the second to HDMI.

    Today I left my computer alone for a while and when I returned both monitors were blacked out. As I shook the mouse the main monitor came back to life but the second monitor didn't. I tried to click around to see if it would wake it up but didn't get any response. When I entered "Display settings" instead to have two rectangles side by side representing my two monitors there was nothing meaning that Windows was seeing only one monitor.

    Long story short I had to reboot the PC to fix the issue. I use exactly the same two monitors that I used in Windows 7 and I NEVER had such scenario before. Now I am anticipating that it will happen again any time my screen sleeps.

    Any idea?

    Thanks!

    :)

  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.
