LG monitor is detected but doesn't function

I just bought a new LG monitor to use as a second monitor with my HP laptop (Intel Integrated graphics) running Ubuntu. In my Settings > Display I can see my monitor detected in the GUI but on the monitor itself it says check your HDMI connection.

I searched a lot, and found LG has Dual Monitor software, but it is not provided for Ubuntu. I tried to use xrandr tool but it did not help.

So far on my another Laptop having ubuntu and VGA port its working over there so the problem is with my HDMI driver. I have looked for intel drivers on this but don't know will it solve my problem or not.

xrandr --verbose

I wanted to install a second monitor to my desktop via HDMI. In the boot process-the HDMI-port died. I fixed this by disabling the X.Org X server Nouveau display driver and to install and select the NVIDIA binary driver 340.96 in the Ubuntu Software & Updates -> Extra drivers menu.

Now I got a dual screen configuration.
