    Installing Secondary Monitor HDMI (LG brand) Windows 10

    Hi all, trying to setup up a secondary monitor (LG 24MP58) for my Lenovo Yoga 900 tablet...to no avail. Everything seems to be assembled correctly, but absolutely no response from the LG. Doesn't even light up or appear to be "trying" to work. There are no physical buttons or controls of any kind, on the monitor. Win 10 generated a Generic PnP monitor in Devices. HDMI is connected to Type-C USB port on tablet via Insignia adapter. Would eventually like to have a duplicate of my tablet screen on the LG.
    Any help or suggestions greatly appreciated.


    Additional info:

    HARDWARE tab

    Generic PNP Monitor properties

    Device Functions:
    EP-HDMI-RX Intel Display Audio
    Generic PnP Monitor

    Manufacturerr: Std Monitor Types
    Location: On Inte; HD Graphics 520
    Device Status: This device is working properly (yeah...right)

    Press the + P keys and select Extend or Duplicate and see what happens. You stated "HDMI is connected to Type-C USB port on tablet via Insignia adapter." Did you install the drivers for that adapter? I have a portable USB 3 monitor I use on my laptop, I have install Display Link for it to work VIA USB.

    AlphaN, thx for the reply and suggestion. I tried the Win Key + P several times and nothing seemed to change. The Insignia adapter cable is about 7" long. The HDMI cable plugs into one end and the other into the Type-C port on tablet. Don't think it needs a driver, I know nothing about it.
    On another thread, someone stated that the Windows 10 graphics driver doesn't allow for secondary monitors. I don't have a clue if this is true or not. There was also a CD included in the packaging for the LG that looks like it contains drivers and software program for on-screen control. When all else fails...read the manual. Guess I'll get a lesson in driver installation. Thanks again for the help.

    The CD with the monitor is a monitor driver, typically not needed for the most part, at least I haven't had the need to specify a monitor for a while. sometimes it's needed to specify to the system a specific range of resolutions the monitor is capable of. Now it could have the display link SW on it, refer to below.

    Sounds like you may want to check the installed display driver (Graphics card) for the tablet, or, hearing as alphanumeric did, I think you need something to enable the USB like display link.

    Natively, hooking a monitor to a USB is not going to get a response from windows, it doesn't know a monitor is there, hence the additional software like display link.

    I'm pretty sure your USB to HDMI adapter is going to need a driver. Windows doesn't see it as a Monitor, it see's it as a USB device. My portable monitor is USB by design. It doesn't need an adapter. In my case Windows knows what it is and installs Display Link all on its own. I'd go to the manufacturers web site for instructions on use and setup of your USB to HDMI adapter..
