Connecting Your Computer to a Classroom Projector

Introduction

This page explains how to make a classroom projector show your computer's screen.

Video Connectors

Before connecting, make sure you know what the different connectors look like.

VGA HDMI

If your computer doesn't have a port to match one of these connectors, you'll need to use the video adapter that IT gave you when you received your Biola computer.

Audio Connectors
