When Renting or buying an DLP or LCD Multimedia Projector you need to match the brightness of the projector to your audience and room size as well as consider your projector video.
(PRWEB) January 5, 2005 -- Larger rooms and audiences require higher bulb
strength brightness. Projector bulb strength brightness is measured in ANSI
lumens or lumens. You also need to take into account the primary use of the
projector, full motion video vs. static data.
Projectors range from around 650 to 5000 lumens in brightness. Presentations where the lights are on are the most desirable, because you can interact and demonstrate off-screen with your audience.
Another consideration is portability of the projector. Lower lumen units are the most portable. As a general rule, as you increase bulb strength brightness, you reduce portability. High lumen projectors are larger and weigh more than low lumen projectors.
Less than 1000 lumens -good for low ambient light, presentations.
1000 -2000 lumens -These are the most popular units being sold and rented today. Very practical and will work with some ambient light.
3000 lumens -Much Larger unit than the1000 to 2000 lumen units. Good for audiences of less than a hundred with ambient light.
5000 lumens - For audiences of 100 or more under brighter lights
6000+ lumens - For large events like conventions, conferences and tradeshows where thousands of people need to view a presentation at the same time.
LCD Projectors vs DLP Projectors
LCD stands for Liquid Crystal Display and DLP stands for Digital Light Processing. LCD is an analog-based display technology employing 3 fixed panels of pixels (one panel each for the RED, GREEN, & BLUE components of an NTSC video image).
LCD also delivers a somewhat sharper image than DLP at any given resolution.
LCD projectors work better for static Microsoft PowerPoint® presentations or detailed financial spreadsheets. DLP works better for full motion video.
LCD projectors usually produce significantly higher ANSI lumen outputs than do DLP projectors with the same wattage lamp.
DLP projectors have a much higher pixel “fill factor” than LCD. DLP-based projectors generally produce a much smoother looking image compared to LCD-based projectors of similar resolution.
DLP-based projectors have a high contrast ratio and efficient use of light. Contrast ratio is figure of merit that compares the ratio between the brightest white and the darkest black that a projector can produce. Generally, a better contrast ratio leads to better black levels and, therefore, a more realistic presentation of darker scenes in movies and TV programs.
DLP projectors consists of a single chip rather than three in LCD projectors. DLP projectors tend to be more compact because they have fewer components.
All of the current 3-pound portable projectors on the market are DLP projectors. Most LCD projectors are five pounds and up. The higher lumen models are significantly heavier and larger. High lumen projectors are not considered portable.
Should I buy or rent a projector?
LCD and DLP projectors are available for rent or purchase from Rentacomputer.com.
So should you buy or rent? That depends on how often and where you need the projector. If your presentation is in another town, lugging a projector thru airports can be a high risk hassle. You can easily damage a projector by dropping it out of a luggage compartment. Never check a projector thru baggage at airports either. Baggage handlers will treat your expensive projector like a suitcase.
If you are planning on using a projector at a fixed location over a long period of time, then purchasing a new projector is a good idea. Never buy a used or refurbished projector unless it comes with a new bulb. Bulbs are very expensive. Projector bulbs cost between $200 to $500 for the more portable units. They cost up to $2000 for the higher end projector units.
