How to Connect an LCD Projector Hooked to a Desktop

LCD projectors have replaced overhead projectors in many classrooms.

If you walk into a classroom these days, you will notice that LCD projectors and computers have replaced overhead projectors and transparencies. An LCD projector gives teachers more flexibility than standard overhead projectors. Teachers can create presentations that include slide shows, video and tutorials in advance and show them on the projector. LCD projectors and computers are simple to hook together.

Things You'll Need

• LCD projector
• VGA cable
• Power supply cord

Instructions

1. Unplug your computer's monitor cable. Plug in the LCD's VGA cable to the location on the computer where the monitor was plugged in.

2. Plug the other end of the VGA cable to the computer port on the back of the LCD projector.

3. Plug the power supply cord for the desktop into the wall.

4. Plug the power supply cord for the LCD into the wall.

5. Turn on both the computer and the LCD.

6. Size and focus the image that is being projected through your LCD by turning the ring on the lens.
