    WINDOWS 10 NOT RECOGNIZING 2ND MONITOR


    After installing Windows 10 I am unable to get my second monitor to work. The monitor says, "no HDMI signal from your device." This monitor and video card was working fine before the upgrade. I contacted support case number 1032675835 and after going through the instructions of this case I still can't access my second monitor. Also, how can I see what kind of video card I have installed without taking the case off?

    :)

    Windows 10 Not Recognizing 2nd Monitor After Updates


    Here's the Laptop I'm using, brand new:
    HP - ENVY 17.3" Touch-Screen Laptop - Intel Core i7 - 16GB Memory - NVIDIA GeForce 940M - 1TB Hard Drive

    I'm using a 2nd monitor that's worked since I've got them both a month ago brand new. I'm using HDMI to HDMI for input and after auto-updates, now nothing I can do will get it to recognize my 2nd monitor, which is this one:
    Acer - 27" LED HD

    Everything worked perfectly, now it's like I don't even have a 2nd monitor. Drivers are updated, I tried restarting. Nothing works. Any suggestions?

    Here's what it says:

    WINDOWS 10 NOT RECOGNIZING 2ND MONITOR

    Windows 10 will not recognize 2nd Monitor after upgrade.

    After upgrading to Windows 10, my 2nd monitor is no longer recognized.

    Monitor is Acer and laptop is Asus. Monitor is connected to docking station as VGA port will not connect directly to laptop.

    Have tried updating drivers and device manager will not detect my monitor either.

    What's the fix?
