The most important aspects of a home LCD projector are its feasibility and efficiency, combined with its usefulness. Compared to the CRT projectors, an LCD chip is amazingly small. An LCD projector is also a viable option in terms of power consumption, which is quite low.

LCD home theater projectors are ideal for business presentations, since they operate successfully in rooms where light is inadequate. An LCD projector is also the most viable and admirable choice for home theater use. One of the key features that make LCD projectors popular is that they are reasonably priced compared to CRT types.

However, the home theater LCD projector is not free from limitations. An LCD projector can frequently display “”the screen door effect”". As the screen consists of separate pixels, the pixels can be evident on a big screen, thereby giving the illusion of seeing the image through a “”screen door”".

An LCD chip consists of a section of different pixels, and in the event of one pixel burning out it presents an irritating black or white blotch on the projected image. Separate pixels cannot be restored, and if a single pixel burns out or the number is greater, the complete chip has to be changed.

One of the crucial factors that should be given adequate emphasis is the fact that the LCD light source in an LCD projector must be substituted from time to time according to the use of the projector. The ideal time to effect the necessary change should be after every 1,000 to 2,000 hours of use. However, the cost can be quite high, going up to a few hundred dollars. Changing the bulb also has its own advantages, since a fresh lamp refreshes the brightness and contrast, and the user can fit bulbs without much difficulty.

LCD projectors are the modern equivalent of the slide and overhead projector. LCD projectors use a small and usually colored LCD panel placed before a bright lamp, with the images on the screen provided by sources such as a DVD, VCR or a computer. LCD projectors are generally smaller in size and more easily transportable than former systems. Armed with a lens capable of projecting the images on any surface with a flat plane and not requiring supporting furniture like a big-sized television would, LCD projectors are getting increasingly viable with each passing day.

There are certain things to take into account when purchasing an LCD projector. The projector’s resolution generally determines the price; the higher the resolution, the greater the price. If the need is for minute details to be precisely displayed, then higher resolution projectors are the way to go. The LCD projector’s light output depends on the lumens rating, i.e. the higher the lumens rating the brighter the light output. For classrooms, projectors of 1000-2000 lumens suffice; for big conference rooms, the ideal projectors would be those between 2000-3000 lumens.

The ratio between the brightest and darkest spots of an image is called the projector contrast. When purchasing LCD projectors, it is feasible to go for contrasts of 400:1 or higher. This way the best and the clearest pictures are achieved.

If the projector is to be carried around to different locations, then it is best to purchase a light projector. Many LCD projectors today weigh below five pounds. The lighter projectors generally cost more though. Also, it is viable to get an LCD projector with multiple ports, in the event that you want to connect multiple video or computer sources to the projector simultaneously. Another factor that should be considered is the durability of the lamp. Replacements can be an exorbitant deal. A lamp life of 2000 hours is just about ideal.
