    Black Screen after install, not detecting 2nd monitor, cannot use 1st


    Evening, folks.
    I am having a pretty critical issue with my laptop after installing Win 10 for the first time. It seems like it is not detecting my second HDMI monitor. I did see that this was an issue previously resolved, but my predicament is a bit different. I use my second monitor as the primary due to the laptop monitor not working. As it is, I have been sitting for close to an hour on a black screen due to my main monitor not being picked up and no way to visually walk through to make it my primary again... If that is even the only problem. Are there any ways I can switch to my main monitor (2nd monitor) worth no visual representation whatsoever? Hope I can get some assistance on the issue as this has rendered me computerless for the time being. *Sad
    (Typing from my phone, so excuse the awkwardness of my writing. *Smile )

    :)

    Windows 10 can't detect my second monitor

    Thank you for confirming. We can do the following:

    When the second monitor is not detected, we need to isolate if it's the monitor, the cable connecting them, or the port. We suggest that you remove your 1st monitor, then use the 2nd monitor as your 1st monitor. After that, connect the 1st monitor as the
    2nd monitor.

    Usually, this it's driver-related. Windows 10 won't be able to detect the 2nd monitor if the monitor driver is out of date or faulty. We recommend, rolling back to the previous installed graphics driver and monitor driver if it updated. Otherwise, update your
    graphics and monitor drivers on the Device Manager. To do so, follow the steps below:

    • Type Device Manager in the Cortana search bar and press Enter.
    • When the Device Manager window appears, click the Display adapters and right-click the item below.
    • Select Properties, then Driver tab, and click Roll Back Driver and follow the on-screen instructions.
    • Expand the Monitors, then right-click the second monitor and select Properties.
    • Click the Driver tab, and click Roll Back Driver and follow the on-screen instructions.

    If the issue persists, update the drivers. You can manually update the driver by visiting the websites of your graphics card and monitor manufacturers to get the fully compatible drivers for Windows 10. You can run the Find
    and fix problems with devices and hardware
    to automatically check for driver updates. Additionally, we'd like to know the make and model of your graphics cards and monitor?

    Post back anytime at your convenience.

  3. windows 10 creators build loses desktop icon overlays on 2nd monitor

    I have 2 monitors.

    After upgrading to windows 10 creators build the icon overlay for shortcuts on my desktop are missing from the 2nd screen.

    If I move a shortcut from the 1st monitor to the 2nd it still shows the overlay, after I press F5 it loses the overlay, moving it back to the 1st restores the overlay.

    Black Screen after install, not detecting 2nd monitor, cannot use 1st

    HI and welcome to the forum! *Smile

    Ohh, that is an annoying issue...
    If this happened to me inside Windows, I would try the usual keyboard combinations, which should switch the output device. E.g. on my make and model it would be Fn + F5, I believe. It may be different for you though. Maybe the manual or a search on the internet will tell you, what this combination is for your PC.

    Another idea might be to use a different monitor: Old and VGA should basically always work.

    Another aspect is: For these shortcuts to work, your keyboard must have been detected properly. Most likely it has been, however, there are a few cases, where people had problems with this Fn stuff after the upgrade. Also I don't know, where exactly in the installation process you are... In the worst case, which I don't know whether it's the case or not, such Fn stuff maybe generally is not working there, even if the keyboard got detected correctly.

    As a last resort, maybe it would be an idea to look at a YouTube video to find out, where in the install you have to hit which buttons and to use the keyboard to do that blindly?

    Thanks for the response!
    Sadly, none of the Function commands seem to issue a response. *Sad I also wish I knew where I was in the installation process. Finally up and got the courage to power the laptop down late last night. A friend of mine told me that this is a known issue with NVIDIA cards; that is, only being able to use one monitor at a time. Maybe trying different monitors will do the trick. I'm half tempted to crack the thing open and manually unplug the laptop monitor from the inside... Thankfully, I'm not that desperate. Yet. *Smile
