How to Connect Laptop to a Projector or a Projector to a Laptop

Many of us like to sit back and enjoy a movie or a game on a big screen and this can be easily done if you know how to connect projector to your laptop.  Traditionally a VGA cable is used to establish connection between a laptop and a projector.  Connecting a projector to a laptop is really simple once you try to do it.  Follow the step by step instructions given below:

Step 1: First make sure that your laptop and projector are switched off. This is an important safety precaution and it is highly recommended to power down all appliances before connecting the projector to the laptop.

Step 2: Locate the VGA port or connector at the back of your laptop. It is designed to take in 15 pins and this is the output port that allows you to connect to an external monitor or projector.  In some new models the VGA port is replaced by the HDMI port which is exclusively used for high definition connection.

Step 3: Connection Ports Including VGA and HDMI

Step 3: Next locate the VGA port or connector at the back of the Projector or LCD screen. This is the input port which allows you to connect to a laptop. This usually has the same number of pins if it is the same port. Sometimes in certain advanced models of projectors an additional HDMI port is provided. This is used for High Definition Media Interface which means you can use this option for playing videos in high definition with better clarity and detail.

Step 4: Insert the respective ends of the VGA cable to the corresponding ports on the laptop and the Projector or LCD. Make sure that they have been inserted in the appropriate ends firmly and tighten the screws on the either sides of both the receptacles. This is quite simple to do and can be tightened using your bare fingers. But it should be noted that in case of an HDMI connection the screws are not present. In this case it would suffice if the wire is plugged in as far as it would go on both ends. However it is necessary that establish a proper connection because there is a possibility of a poor connection to result in a distorted display. Sometimes a loose connection may cause trouble to your computer so make sure the connection holds good.

Step 5: Now it’s time to switch ON your projector and then switch ON your laptop. At this point, most business projectors and laptops will sync automatically but you might have to wait until the laptop is booted. If you still don’t have an image, most likely it requires toggling to activate the VGA port. Activation of the VGA port can be accomplished by using the specific buttons on your laptop. You are required to simultaneously press on the function (Fn) key and F8 or the LCD button on your laptop. This button will have to be pressed multiple times to scroll through the list of available options and the most apt option can be selected. Options to turn off your laptop screen and display only the projector will be present in order to conserve power. For some applications, both the laptop screen and the projector can be turned on for dual viewing. The LCD button can be identified with the picture of two squares on it or having the letters “CRT/LCD”.

A point to be noted: Although the basic operations are the same in all the laptops and computers, minor differences are noted with different brands according to the way they are programmed. If necessary, consider referring to the Operation manual which comes along with your laptop. There you will find step by step instructions specific to your model which will be of great help. Sometimes the laptop may require some special drivers to make connecting projector to laptop relatively easy. In most cases this driver will be pre-installed when the computer arrives but in rare exceptions you might have to download it from the internet.

Some projector brands come with “plug and play” connectivity that works with a USB cable.

Before you begin your presentation, you may want to adjust the picture being displayed. Adjustments in terms of brightness, contrast, focus, size and sharpness of image are possible. The adjustments can be made on the LCD projector. Usually the focus and zoom options are present as sliding options near the lens. Other options such as contrast and brightness can be done on the control panel of the projector. Once an option is selected it will remain the same unless it is explicitly changed the next time. Though most issues are covered in this passage you might want to have a quick look at your instruction manual before connecting projector to laptop.
