A projector is a device, which can be connected up to a computer, laptop, VCR etc. It projects an image or clip onto a large screen or a flat surface. Although a data and video projector is rather powerful, it is simple to use. Here I shall explain how to set up and work a projector.
Locate the monitor output connector on your computer:
If you are using a desktop computer, this will be where the monitor connects to your computer at the back. You will need to unscrew the VGA (video graphics array) connecter which will then make this connector available. When you do this, your monitor will not receive any signal and will send the screen black.
If you have a laptop, there is no need to unplug anything. Instead you just need to look at the back or side of the laport to find a port. When finding it, you may find that it will have an image of a port or have words such as ‘Monitor,’ ‘VGA Output’ or ‘Video Output.’
Plug the data projector’s VGA cable into this connector:
After finding out where the Monitor VGA cable is, you will need to take out the VGA cable which is with the projector. You will be able to identify this cable, as it will look like this:
Take out one end of the cable, then screw it onto the Monitor Output connector, which is on the back of the computer, or at the side on a laptop.
Plug the VGA cable into the projector:
Locate the VGA input connector on the projector. Each model may be different, but in despite of this, the port will look the same as the Monitor Output Connector on the computer. It may be labelled ‘Computer,’ ‘Input,’ or ‘VGA Input.’ Plug the free end of the cable into the port of the projector.
Set up and turn on the projector:
Now you will need to point the projector towards a flat surface or white screen. If you find that the VGA cable is too short, you can buy an extension. At this point, you may now turn on the power for the projector.
Make sure the video signal is getting to the projector:
When the projector warms up, you may get a picture straight away. If not, there may be a number of things you can do to try and work out what’s wrong:
If you are using a laptop, try pressing the ‘Function’ Key, possibly labelled Fn, and F3 on your keyboard together. This will generally put you through three different video which are:
- Video to monitor only
- Video to both monitor and projector
- Video to projector only
If you are using a computer, you may need to press the source button, which will be on the data projector. Each time you press this button. The projector will cycle through a variety of video sources, until it finds one which works.
If all else fails, make sure that you have taken the lens cap off.
Adjust the projector so that you can get the best quality of image and sound:
You can raise or lower the feet of the projector, if you want the image to be raised or lowered.
If the image is blurry, you can adjust this by using the focus knob, on the back of the projector. It can be focused by the lens itself also. Some projectors also have a zoom lens, which can also be adjusted from around the lens.
This type of projector, also has built in speakers, which can have its volume altered, using the VOL – and VOL + buttons.
For more advanced settings, you can press the MENU button on the projector. This will fetch up an on screen menu, which will allow you to change the colour, brightness and contrast. This generally doesn’t need changing.
Now the projector is now ready to be used.
When you are done using the projector, you must do the following:
- a) Turn off the data projector.
- b) Unplug the VGA cable from the projector and the computer.
- c) If you are using a desktop computer, reattach the monitor’s VGA cable to the computer (the monitor will begin working again.)
- d) Pack up the projector’s VGA cable and power plug.
- e) If the projector is noticeably hot, give it five minutes to cool down.
- f) Pack up the projector in its case.
