Screen Projectors - Be a Wise Consumer

Technology can be confusing. Knowing the correct screen projector to purchase can be a bit daunting. Some of us, if we are perhaps older, may not keep up with the newest and greatest technology so we can blink and get left behind.

Here is a little history to take you through memory lane. A few years ago, it seems like only yesterday but perhaps it has been 10 or 20 years ago the screen projector industry was embarking on new territory. It was an exciting time because the screen projectors were coming of age and the technology then was a marvel to behold. Now, look at what we have. We have gone from what used to be called a marvel, the analog screen projectors to the now popular digital screen projectors.

The home screen projectors have changed significantly over the last few years. Here is what we used to have and how it has evolved.

The CRT

The dramatic improvements made in the picture quality of screen projectors have been significant. The CRT is the Cathode Ray Tube projectors. These screen projectors give a film like image. That is a nice way of saying it is not crystal clear and sharp. These screen projectors do not measure the structure of the images in pixels. These type of screen projectors were invented before pixels were invented. In the days past the CRT were considered to deliver stunning picture quality. There are many CRT screen projectors still around. To operate these projectors efficiently the projection screen needs to be of high quality. The level of grain needed for these projectors is a 1.3 to a 2.5-grain. This will depend on the size of the screen and the size of the desired picture. These type of projectors used in the film industry are not typically cheap. The cost used to be around $35,000 - $50,000. The advantage of this type of screen projectors is that they could be used for a good quality large picture in a large room such as a conference room or arena. These were typically very large and heavy weighing about 150 to 200 pounds. This required a substantial structure to support the projector. This was not a card table type screen projector.

Another aspect of the CRT was that the placement of the projector to the screen was crucial. To get optimum results one would have to take care to be precise in the placement, with the correct distance and elevation. Many times it would take a professional to set these up right so the picture quality was there. The CRTs have been known for the amount of light they can put out, hence their standard use in larger rooms. However, the actual picture that was put out was considered, perhaps in retrospect, as a dim picture. With the need to recalibrate them every six months or so, these were really high maintenance projectors.

With the invention of the digital screen projectors the prices on these CRTs have begun to plummet. You can pick them up for much less than $5,000 and even as little as $2,000. It is all about supply and demand. The demand is just not there and it is dwindling fast. The production of CRT screen projectors has dropped off drastically. Many if not most companies are no longer making these types of projectors because they simply are not in demand.

The Digital Screen Projector

The digital screen projector is the new kid on the block, so to speak. However, digital projectors are in use everywhere, from the commercial use to the home theaters to the home living room. There are a few reasons for the popularity of these screen projectors.

Compared to the CRT units these are much quieter, of course much smaller and lighter in weight but the pictures are not only brighter but also much sharper and clearer images. The new screen projectors come in different quality units. Some are being sold for home theater use when they are just presentation units that are repackaged with different labels. When the units are not made for digital movie screen projectors the quality is sacrificed. The digital screen projectors can be purchased for $700 on up. Some of the most popular brands are: Sony, Runco, InFocus, Vidikron, Marantz, Benq, Panasonic, Sharp, Optima and Sanyo. Make sure you know what your needs are and what you expect of the unit. Then when you go to purchase the unit, search until you find what you need. It is out there.

The difference between presentation units and home theater digital screen projectors is that the presentation units will have the brightness but not the picture quality. Digital screen projectors will have dpi, which is dots per inch and these will have pixels. The greater the pixels the better the quality of the picture. If you are giving PowerPoint presentations it is important to have the brightness but the clarity is not essential. When in the marketplace the rule of the day is buyer beware. Know what your needs are and what the unit will be used for primarily and buy accordingly. Make sure you test out the make and model you purchase. Test it out for the brightness and the picture quality. Make sure you know what type and the quality of the screen projectors you are buying.

Now you are an informed consumer. With this type of information you should be able to walk into the store as a more informed consumer ready to ask some serious questions and expect some serious answers before you plunk down your money.
