DLP Projectors Tips

The Way DLP Works

DLP, short for Digital Light Processing, is powered by a single semiconductor called a digital micro-mirror device (DMD). This semiconductor, invented by Texas Instruments, contains almost 2 million tiny, hinged mirrors. Red, green and blue light is filtered and directed onto the DMD, which switches on and off up to 5,000 times per second. The various streams of light are reflected by the 2 million mirrors and onto a screen, which creates the image. Some high-end DLP devices use three DMDs, one for each stream of light. DLP offers a high-contrast, high-quality image that clearly beats traditional CRT and rivals LCD.

DLP Projectors

If you've decided on a DLP projector, look at the leading brand names: NEC, Sanyo, Hitachi, Mitsubishi, InFocus, ASK-Proxima, Sharp or Epson. Other things to think about include the following:

* Resolution – Are you going to be projecting simple PowerPoints, spreadsheets with lots of numbers, or detailed images and video? Each of these requires different levels of resolution.

* Portability – Do you need to bring the projector on the road or is it going to stay in one place?

* Price – This is going to depend on how you answer the above questions first. But if you need to stay within an overall budget, this is going to be among the most important considerations.

* Brightness – Are you going to always be in dark rooms? How much detail do you need to show? Generally, DLP projectors will run between 1,000 to 3,000 lumens, with the higher numbers brighter and more expensive.

Digital Light Processing

Here's how digital light processing works: Simply put, the white light of a projector lamp is passed through a color wheel, which turns the white light into colors of green, red, and blue. These colors are then transferred to the DLP chip, creating as many as 16 million colors.

ROI on a DLP Projector

ROI on a DLP projector depends on how much use you get for the money. If ROI is particularly important to you, consider any of the following:

* Get a portable projector – It will get much more use than a projector that sits in one room permanently.

* Get the brightest projector you can afford – That way it can be used in more places and won't always require a dark room.

* Make lamp life span a consideration – Try to get a rating of at least 2,000 hours.

* Also, remember that DLP projectors can be used longer and do not run as hot as LCD projectors, potentially giving them a longer overall life.

DLP Pricing

Pricing on DLP projectors varies depending on what type of features are needed. If you are looking for something to use in the home, DLP projector prices will fall within the $1,000-$3,000 range for a new projector. There are many manufacturers who offer refurbished models for as low as $800. If you need many features for a business or school, the cost is considerably higher, reaching up from $4,000 to $7,000 for the brightest projectors on the market. However, the investment can be worth it if you can cut costs for otherwise-needed supplies with a regular projector.

Lamp Replacements on DLP Projectors

The cost of replacing your projector lamp can be expensive -– from $150 to more than $500, depending on the projector type. When you're looking to buy a DLP projector, this can be one of your purchasing decisions. Different projectors are rated for different life spans on their factory-installed bulbs. For example, some projector lamps are expected to last no more than 1,000 hours. If you plan to use the projector a lot and replacement cost is important to you, make this part of your purchasing considerations.
