How to use a external monitor for your laptop

As we all know the laptop's advantage compare to Desktop is light and portable. Mst laptop's screen is between 12 - 17 inch. Generally the 17inch laptop is a little heavy (about 7 pounds), in the market 60% laptop are 15-16 inch wide screen. When we use our laptop to watch movie or play some 3D video game, the laptop small screen is the too small to work. So we use another 21-inch or bigger monitor as a external screen.

But how to use a external monitor for your laptop? The content below take Dell Inspiron 1545 battery for example to introduce the detail step.

1. Buy a External monitor. You can buy a suitable size monitor for your need. Usually watch movie need 21-inch or more, playing Video game 19 inch screen is enough.

2.Buy a connect wire. Most laptops built today include an external monitor connection. Most are VGA, but some are starting to include DVI digital video connections instead. You just need to buy a VGA or DVI wire to connect the laptop to monitor.

3. Connect one end of the DVI or VGA cord to the DVI or VGA port of your laptop and the other end to the monitor. Your laptop (XPS M1210 battery) should automatically identify the external monitor as a new hardware device.

4. Active the external monitor. They are not enabled by default. You need to take action to send video out that port. Typically, and this varies from laptop to laptop, however is often either: Fn + F3, F4, F5, F8, or F9. The function key will often be labeled as CRT/LCD and/or have a picture of a monitor on the key or close to the key.

5. Close the laptop screen. Some laptops also have the ability to have the display on both the laptop and external display and/or one or the other at a single time. Laptops with this ability can switch between these modes by continuing to press the same function keys until in the mode the user wants. Dell Inspiron 6400 battery also is Fn + F7.

6. Set the new resolution or "size" pixels in laptop Display setting. As the likelihood of the LCD and the external monitor being the same resolution or "size" in pixels is very low. Unless the monitor is detected or setup in the operating system, it may not work properly or will only display at the default resolution. If you wish to change the external display's resolution, make sure the monitor is detected by the operating system.

In the end I suggest you do not use your laptop battery when using external monitor. It may exhaust your laptop battery power in 1 hours or less.
