Display connector: HDMI

The computer has a build-in LCD screen. The driver fails to recognize an
external monitor connected through HDMI. The HDMI connection is working because
I can see a mirror of the screen (LCD Panel + HDMI) before booting into Ubuntu
and also inside the BIOS. The problem is still there in Ubuntu 17.10.

According to this:
https://ark.intel.com/products/91832/Intel-Celeron-Processor-N3060-2M-Cache-up-to-2_48-GHz
My Graphic Card is: Intel® HD Graphics 400

I tried installing the INTEL GRAPHICS UPDATE TOOL FOR LINUX* OS V2.0.2 but it
did not solve the issue.
