How to Use a Computer With a Projector

By Andrew Dewitt

  • Overview

    Presentations depend on effective communication, and often the best way to communicate is visually. This is why things like charts, graphs and other visual examples of statics are so important. It also helps to prevent boredom at at your meeting. Having a visual tie to the topic of discussion allows multiple brain connections to be made, which scientists now believe is crucial for effective learning and memorization to take place. Projectors allow you to present graphics along with a presentation. Setting up a projector for your meeting does not have to be a nightmare.
    • Step 1

      Make sure the computer and projector are turned off. Connect the VGA input/output cable to the projector. Screw the cable in place with the small nobs on the side. Check the power cord and make sure that it can reach a power source without getting in the way. Ideally the cord should run against the floor to a power supply under the table.
    • Step 2

      Turn your computer tower around and unplug the monitor from the VGA slot by unscrewing the nobs and gently removing the plug. Insert the VGA cable connected to the projector into the monitor slot and screw in place.


    • Step 3

      Turn on the projector and adjust the legs so that the image is projecting straight and level. Turn on the computer and after it boots up you should see your desktop displayed on the wall or screen. If it is blurry or out of focus turn the the cylinder around the lens until the image comes into focus.
    • Step 4

      Place the projector somewhere that is not directly interfering with your meeting. A good place is in the middle of the table, leaving enough room on all sides for people to take notes. You can also get a wireless keyboard and bring that to the podium with you so that you can change slides or PowerPoint pages easily from the place that you are speaking.
    • Skill: Moderately Easy
    • Ingredients:
    • Projector
    • VGA cable
    • Computer
    • White wall or projector screen
    • Extension cord
    • Tip: Try to get to the meeting at least 15 minutes in advance to set up and get comfortable with your projector. This will help to alleviate any panic that occurs from not only having to give a presentation but to also deal with technical specifics in a hurried manner.
    • Warning:
    • Never leave your projector on for an extended period of time. Projector bulbs are expensive and hard to replace.
