How to connect an external monitor/projector to a laptop?

Most of the laptops available these days can be connected to an external display. These displays can be of different types -  CRT monitor, flat panel display, or Projector. Connecting such display medium transfers the display to the connected device however the control remains with the main laptop.

Usually we would take the help of a tech troubleshooter in our office to get this done when needed. This at times becomes embarrassing, not because you don't know it, but because you are waiting for a presentation and the tech person takes his own sweet time. You do not know what to tell the people who are eagerly waiting for your presentation to begin. Besides that where would you get an IT guy when you need to do this at home. Let us today, learn to do this ourselves.

To do this you will need to connect the device to the laptop's 15-pin video connection on the side/back of the laptop. You will have to use a specific cable. It has 2 ends as shown.  One end of the cable will be connected to the back of the laptop and the other end to the external display. You need not worry to think about that which port do i plug it into as there will be only one such opening at the back of the laptop that will accept this. Besides this you don't even need to think that the end with the pin goes into the laptop or the display device. These  cables and devices are luckily designed in a standard way. You will be able to identify this just by looking at the available ports.. Once connected, your laptop will automatically switch to the new external display In some laptops you may need press certain keys in order to switch from the laptop to the external display.

The keys are different in different laptops. The common ones are : Fn + F3F4F5F8, orF9. You need to press and hold the Fn key and then press the appropriate key. The key is usally there on the upper number pad and will often be labeled as CRT/LCD or have a picture of a monitor on the key or close to the key. If such options are not present you need to refer to your manufacturers website or customer service.

Note - Some laptops have the capability to display on your laptop screen as well as external display simultaneously.
