For the better part of my career I mostly relied on transparencies and an overhead projector to visually explain ideas to groups. With the exception of using a printer to create color images on a transparency, there was little that could be done to improve the quality or efficiency of this training and presentation method.
About three years ago, I borrowed a computer projector and used it for a presentation. I liked it, and started inquiring about the features and costs of projectors. Computer and video projectors used to be big, heavy, and expensive with rather poor image quality. But not anymore. I recently purchased a projector, and I’ll share with you my experience. Now that the price has gone way down and the quality way up, you should consider adding a video projector to your arsenal of training and presentation tools.
