Know that you are thinking about creating the ultimate home theater, but not sure where to begin? Determining how bright your home theater projector should be is dependent on many factors. With business projectors, lumen output is of primary importance, and contrast (difference in brightness between maximum white and deepest black in an image) is a secondary concern. Using a home theater projector will allow you to bring cinematic quality right to your living or family room. Although a good portion of home theater projectors can be ceiling mountable, not all are. Some other features to consider in order to give your home theater projector installation that “wow” factor include picture-in-picture, automatic keystone correction, rear projection capability, and long lamp life.

Looking to buy an LCD or DLP projector, but don’t know where to begin in your buying decision? We have compiled a list of common first-buyer questions that are geared to steering you in the right direction and help you find the right presentation projector for your needs. LCD and DLP technology offer different benefits. Depending on how portable you want your LCD or DLP projector to be, there are a variety of options concerning the size of presentation projectors. How bright your projector should be is determined by the setting that you are going to be using it in.  Brightness is measured in ANSI lumens (or just lumens), and the more lumens produced by the projector, the brighter the projected image will be. Many projectors will accept higher or lower resolutions by expanding or contracting the image to its native (standard) resolution, but what you sacrifice in this flexibility is image quality.

It is important to consider what kind of room should operate for a Board of Home Theater. We can use a family room for this purpose, but we must take into account several points in order to know how viable it is. The type of seating is important not only for comfortable, but also that seat should not as such that you will fall asleep. This is known as 5.1, 6.1 or 7.1. If room size 4x4 meters or less the 5.1 audio system is adequate, it is recommended only 6.1 or 7.1 when the room is large and with enough space behind the seats, the speakers for surround back. The placement of the Speaker is an important point to consider, as this will depend on which of us really sound the surround effect of multi-channel equipment.

This photograph is an example of a family room, It has a High Definition projector PANASONIC A700 1000 lumens WXGA (1280x720). The screen is 2.13m wide x 1.19m high, electric. The sound equipment is an Onkyo 5.1 channel Receiver. The DVD player is from LG with component video and progressive scan, Satellite Receiver and VCR.

Liquid crystal display is one of the two technologies behind flat-panel displays, with the other being plasma technology. LCDs use two sheets of polarized material with a liquid crystal solution between them. Digital Light Processing is a product of Texas Instruments which uses a single chip that is made up of up to 2 million microscopic mirrors to project light. This chip is called a Digital Micromirror Device (DMD). Each of the microscopic mirrors that make up the DMD represents a single pixel. Most people use the term plasma in reference to any flat-panel display, when they are only correct a percentage of the time.  Plasma technology is very different from liquid crystal display technology, although the final product generally looks very similar.

The conventional projectors or handle a format called 4:3 ratios, i.e. have 4 units wide by 3 high. The home theater projectors to handle the so-called Wide Screen or 16:9 format, which is a ratio of 16 units wide by 9 high. The contrast ratio is the comparison between Black and white, with forming this relationship is greater black colors will be more blacks. This contrast ratio is more important for home theater projectors that use of boardrooms. Most projectors for home theater have a more sophisticated video processor that they handle conventional projectors. In most conventional projectors that handle the Zoom can cause the image size between 20 and 30%.

Whether you are an on-the-go presenter working in unknown environments regularly or a home owner that needs a little more flexibility when it comes to designing your home theater, keystone correction is a must-have feature for screen projectors. Many of today's screen projectors, when they receive data from the data source, digitally manipulate (or scale) the image to compensate for keystoning. This allows the projector to digitally correct the problem before the image even reaches the projector lens. Although keystone correction is a great feature for those tough situations, it is still a better choice to make sure your home theater or presentation projector is perpendicular to the projection area to obtain ideal picture quality. Because keystone correction occurs within the projector internally, some image quality is compensated to scale the image so that it is square.

The use of screen projectors previously was plagued with the absolute need to have the projector centered vertically and horizontal on the projection screen to avoid having otherwise great looking rectangular images and graphs turn into unattractive trapezoids.  Lens shift was developed to eliminate this problem, add flexibility in presentation projector placement, and let presenters focus more on the content of the presentations rather than figuring out how to make the equipment cooperate.

Properly caring for your projector is the easiest way to ensure that it lasts and lasts and performs flawlessly when you need it. Some simple steps that you can take include:

• Take the time to thoroughly read your owner's/user's manual that came with your presentation projector. Model-specific information for your projector can be found there which may include special care instructions for your particular make and model.
