    Still doesn't work.
    what I came up with is when I uninstall the intel HD graphics 630 driver and restart the system, the second monitor works fin till the pc detects the graphic card and installs the driver for it then the second monitor goes to sleep.
    I tried to install an older version of the driver and still not working

    The PC is detecting the second monitor as it shows under "display setting" but not sending a signal. Any idea why?
