How to connect an external monitor to an HDMI or VGA Laptop easily

The monitor is one of the most important parts of any computer, and sometimes our work schedule requires that we have more than one. If we have a laptop, this is quite easy, so today we will see how to connect an external monitor to an HDMI or VGA Laptop easily.
