This is basically the cheapest projector available, however the technology is older. Some other advantages to CRT projectors are that they last; the tubes retain their luminosity. More professional CRT projectors should be able to display graphics at large dimensions. They present a richer black compared to LCD or DLP projectors. Also, CRT projectors should not have what is recognized as a “rainbow effect”, which can develop with DLP projectors. Just like any projectors, CRTs have their downsides at the same time. CRT projectors are generally bulkier and heavier than LCD or DLP projectors and at first demand extra adjusting and time to correctly arrange. They are also a larger energy drain, and will have a higher operating cost.
  • LCD Projector: A LCD or liquid crystal display projector works by sending light through a prism to make the red, green and blue lights needed to show the image. Benefits In LCD projectors are generally their compact sizing and ease of portability. They are able to project the graphic upon any sort of flat surface. They maintain contrast, even in vivid places and are usually not affected by glare. They may be wall mounted and do not require a great deal of energy to use. A few drawbacks are the washed out blacks they project, image warping can happen, pixels can die and ghosting may occur.
  • DLP Projector: A DLP or digital light processing projector is a trademarked technology owned by Texas Instruments. They function by using mirrors that represent pixels in the projected picture. The more mirrors that are present, The greater the resolution. DLP projectors are usually preserved for higher end theaters. They’re more costly, and can encounter what is known as “rainbow effect”.
  • Plasma Projectors: The benefits of plasma projectors are that they are smaller, can be mounted on walls, are more lightweight and less awkward than CRT projectors, they provide truer color in comparison with a LCD projector, they supply a wonderful, vibrant black, can be watched at broad perspectives, they also usually do not suffer from what is known as motion blur. There are draw backs, however, which include things like: they may be susceptible to screen burn in, the intensity may lower gradually, may be susceptible to glare in lighter spaces, they require a lot of power to work, they are bigger than LCD projectors as a result of manufacturing of the technology.

What could I project the graphic onto?

On the list of most common questions people have when considering home theater projectors is whether or not to project the picture on a screen or a wall, and what sort and shade of screen to purchase.

  • 3D TVs: Many are top-of-the-line and high-priced TVs, but 3D is fast-becoming an essential element of many home theater systems. The major downside of a 3D TV is the fact that viewers need to wear special glasses to properly watch the 3D screen. There are models which will operate in either 2D or 3D, eliminating the need for always wearing the glasses.
  • OLED TVs: these are organic light emitting diodes, and give you a stunning screening experience. They supply sharp contrast and vibrant colors. OLED TVs also tend to be energy-efficient and quite sleek. At the moment, these TVs are nevertheless costly.
  • Plasma TVs: Plasma TVs have vivid colors, come in sizes up to 150″, and deliver abundant blacks. The screens are made from glass, however, and glare could be or worry. The do provide wider viewing angles as compared to LCD TVs, however. They are thin and can be wall mounted. They are heavier than LCD TVs due to the glass in their screens and are less energy efficient.
  • LCD TVs: LCD TVs are the standard, and are generally the least expensive option. They are far and away the most prominent TV implemented when building a home theater. They are smaller and much lighter weight than CRT TVs and may have screen sizes much larger. You will find down sides in that LCD TVs do not possess the picture quality as some of the costlier options. They’re also less energy efficient. Nevertheless, they are far less costly and a great option for those with limited funds.
