Video projectors have commonly been used for many years in the education and business world to provide a visual aid to presentations and lectures. With home theatres also being a popular feature in many homes these days, video projectors are also commonly used as part of these. If you are looking for the best quality, then a digital video projector can be the best choice these days and these are available in a few different formats.
There are a number of options if you are considering using a digital video projector. There are a few different technologies used in their manufacture with the two most common being Liquid Crystal Display (LCD) and Digital Light Processing (DLP). An LCD projector is typically the simplest and most affordable of the projectors on the market and this makes it commonly available. It uses a light source and three LCD panels to project an image onto a flat screen. A DLP projector uses technology developed by Texas Instruments, the DLP chip. These types of projectors can either use one chip and a color wheel or the higher quality alternative tends to be three separate chips, each one dealing with a different primary color.
If you are thinking about purchasing a digital video projector there are a few things to take into consideration. The first is obviously the type of technology that is used to manufacture the projector. Both DLP and LCD projectors have their advantages and it can really come down to personal preference as to which you feel better suits your needs. DLP projectors have sealed chips which are less susceptible to problems with dust and can also work without air filters and this typically means there is less maintenance involved. However the more affordable one chip DLP projectors can suffer for a problem known as “rainbow effect” which is brief flashes of red, green and blue on the screen when people move their eyes across the screen. LCD projectors on the other hand tend to be more affordable and can produce the same quality pictures for a reduced cost.
Other considerations when purchasing a digital video projector include the resolution, with 1080p typically being the best quality available although other lesser resolutions are available. The brightness or Lumens is also a consideration with the greater this is the better the picture quality will typically be. The resolution and lumens tend to be the most common factors which will affect price. There are a number of manufacturers that produce digital projectors with some of those to consider including BenQ, Epson, Vivitek, Optoma and Sanyo.
In terms of cost LCD projectors typically start around $500 or slightly lower in price. An example of this is the Epson EX31 Multimedia Projector which costs $500 to purchase. This uses 3LCD 3 chip technology and has a plug-and-play USB connection for east set up. The better quality 1080p DLP projectors more commonly start around the $1,000 mark with the Vivitek H1080FD Projector being an example of this. This projector costs $900 to purchase and features BrilliantColor technology to provide an intense, high definition picture. In both cases, more sophisticated models will be more expensive, with costs of up to $5,000 being charged for some projectors.
A digital video projector can be a good choice for your home theatre, classroom or business setting. Whether you choose LCD or DLP technology you will be provided with good quality, high definition pictures. Taking your time to review the various options from the wide selection available should ensure that you get a projector that suits your needs and your budget.
