Screen Projectors - Analog Vs Digital

There is a war out there. It is not being fought on the battlefield it is being fought in the stores around the world. Well, actually it really is not a battle any longer. The war has been won and analog lost and digital won. Let's look at the difference and you will see why digital won.

We will focus on the analog and digital screen projectors. This is a topic that can be a bit confusing to some. With a few minutes of reading you will become an informed shopper so you will know not only what the hype is about but also what your options are and why you will want what you want. Notice we are not telling you what is best because that is an individual choice.

If you are in the market for a new screen projector you need to know what the option are and what the features are and what the benefits are of the features. When we are informed consumers we not only have a more vivid picture of what we want and need but we also become a much more interesting conversationalist. We can share our knowledge with others.

The Analog Screen Projectors

Screen projectors have been around for a few decades now. The older models are analog. These are CRT or Cathode Ray Tube screen projectors. There were a few great aspects to these projectors and there were a few drawbacks. Ironically we don't see the drawbacks until the next new invention comes along. That is how it happened with the screen projectors. The CRT was a marvel and a wonder. It has been used in the larger rooms such as conference rooms and arenas. The CRT was great for that because of it strong brightness, and the images were viewed as being very good quality with the deeper colors and rich color hues. The Analog or CRT screen projectors do not measure nor do they have pixels. That means that there are no dots per inch (DPI) just rich color. That is why the movie theaters used and many still do use the CRT screen projectors. While the DPI and pixels is not measurable with the CRT projectors, many believe the quality of the older analog color is being lost.

The cost for a CRT was between $50,000 and $70,000. Which was significant. The units were large and heavy and cumbersome. But they gave great presentations and as the new screen projectors these were a marvel. These units had some issues in that the set up had to be precise. The distance and the elevation had to be just right or the picture would be severely lacking. This was such an important aspect of running this type of screen projector that professionals would be hired to just set them up.

The Digital Screen Projectors

There are basically three types of digital projectors available today. They are the LCD - Liquid Crystal Display, DLP - Digital Light Processing and LCOS - Liquid Crystal On Silicon. Obviously each one has different advantages for the consumer.

Probably one of the most measurable differences between the analog and the digital is the DPI or pixels. The digital is promoted as better and it does appear so when one watches the HD TVs. However. There are some other factors about the digital screen projectors we need to present.

The digital screen projectors have some very good qualities, which also makes them good choices for use in home theaters. The units are lightweight, small and the setup is simple compared to the CRT or analog screen projectors. Then we also see that the digital projectors have bright and sharp images. The prices are rather affordable with a starting price at about $700 on up to $100,000. If you are using the unit exclusively for home theater use then make sure it was designed for that. The colors need to be vivid with great black color to accentuate the contrast to the vivid colors.

For the digital screen projectors one confusing quality of the unit is the resolution. Remember this, the lower the resolution the smaller the screen you can use without seeing the pixels on screen. Pixels are those dots that make up the picture. However, remember this, the lower resolutions do not support high definition TV. The magic number is 720. Anything over 720 will give true high definition TV. The DPL units have chips in them, some as high as 1920 x 1080. The digital screen projectors are emerging with some significant quality to offer the consumers. Also, these digital units are now coming with video processors to satisfy the needs of the home theater projectors.

When looking to purchase a screen projectors it is important to look at your needs, what the different types have to offer and investigate the different models and the benefits of each one.
