Multimedia LCD and DLP Projectors
What to Know
Clients often ask, “What should I look for when shopping for a multimedia projector?” In many cases, budget will be the most important factor in determining which projector is right for you. Yet, there are a few other aspects to consider when finding your ideal model.
“How large should the projector be?”
• Today’s projectors are much smaller and lighter than ones of the past. Ultra-light portables can weigh less than four pounds and have wireless capabilities. Although ideal for small-group presentations, they are often bright enough to handle much larger venues.
“How can I determine what the aspect ratio of the projector and screen I need should be?”
• For business applications we generally recommend a projector and screen that match the aspect ratio of the laptop you will be using. The default ratio on most new laptops is 16:10. However, to determine what your computer’s aspect ratio is, you can simply divide the width of your screen’s resolution (found in the appearance section of your computer’s control panel) by the height.
• Will your projector be installed in a facility with a local network? If so, you may want to consider a projector with network features to provide remote access to control functions, or to monitor and maintain your projector from a remote location on the network.
• Tracking the hours of lamp usage or programming the projector to automatically turn off at certain times can greatly reduce your cost of ownership.
Other key factors to consider before making a final decision on your projector include:
• Image quality
• Fixed or interchangeable lenses for short or long throw distances
• Native chip resolutions and aspect ratios to match and/or accommodate the format(s) of your sources
• Transitive or reflective light engine technology
• Image chip type – LCD (Liquid Crystal Display), DLP (Digital Light Processing)
• LCOS (Liquid Crystal on Silicon)
• Multi-screen, zoom, mouse, control and digital features
• Intended application and message content
• Projection environment (room size, ambient light, seating arrangement, etc.)
• Intended audience and anticipated user knowledge
